] | #### Description
The frame counter used with ieee802154_security is initialized with 0 at startup. While it is protected against overflow, it is not protected against being reset, and that reset happens whenever the device restarts.
As the key is flashed into the device in ieee802154_security's normal operation, and the sender LL address is constant per device, the same nonce (varying only through the resetting frame counter) is used in the AES encryption multiple times. Reuse of the same (nonce, key) breaks confidentiality guarantees.
(AES-CCM is used here, so AIU it's [not as bad](https://crypto.stackexchange.com/questions/26790/how-bad-it-is-using-the-same-iv-twice-with-aes-gcm) as if GCM were used, when there'd be key leakage).
#### Steps to reproduce the issue
(All done on microbit-v2; I have high confidence in this working on any 802.15.4 encryption capable device).
* Sniff for packages, eg. by building the default module.
* Build the gcoap example with `USEMODULE+=ieee802154_security`
* Send out a GET request to the sniffer module, path `/hello_world/coap`
* Repeat the request a few times (to cancel any jitter in the number of messages sent during startup)
* Reboot the device, eg. by power cycling it
* Send out GET requests to the same address, path `/.well-known/core`
#### Expected results
* Requests after the reboot use different sequence numbers.
#### Actual results
* Requests after the reboot start from the same zero sequence number again.
* Requests have byte-wise identical requests in regions of equal content, eg. (asterisks mine)

(Note the `20` in the second row where the shared "l" of "hello" and "well" is, as well as the "\x04co" of the "core" / "coap" option; variation is in MIDs (first row bytes 12-13), token (second row, first 4 bytes) and the diverting texts).
#### Versions and cross-references
All since introduction in 2021.01 until current HEAD.
Since #16841, the module in question has been marked as experimental.
Disclosing this has been discussed in the [closed security list](https://forum.riot-os.org/t/security-issues-with-ieee802154-security/3348/11), and was deemed responsible given the overall circumstances.
[CVE-2021-41061](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41061) has been assigned to this issue.
#### Road forward
This is not trivial to fix, as we don't have any committed persistence inside generic devices, and even with 6TiSCH minimal security the problem is just shifted (for [section 4.6](https://www.rfc-editor.org/rfc/rfc8180.html#section-4.6) requires monotony of ASNs on the device which is equivalent to this problem, although it'd shift the attack difficulty to an active replay of old beacons). Likewise, most advanced modes need persistence, until (with [ace-ake-authz](https://datatracker.ietf.org/doc/html/draft-selander-ace-ake-authz-03)) asymmetric negotiation comes into play.
Off my head I don't know any standard solutions that can do with neither asymmetric cryptography nor local persistence; some randomness based scheme could possibly be deployed but it'd be very ad-hoc, custom and eventually not easier than the existing solutions.
I think that the discussion in #16730 can serve as a starting point. | ieee802154_security: Nonce is reused after reboot | https://api.github.com/repos/RIOT-OS/RIOT/issues/16844/comments | 10 | 2021-09-14T07:24:59Z | 2023-04-19T22:54:35Z | https://github.com/RIOT-OS/RIOT/issues/16844 | 995,683,197 | 16,844 | 2,484 |

] | Hi OS4ED Team!
I believe I've discovered a reflected XSS and a local file inclusion vulnerability in openSIS V7.6. I don't think they have been reported yet.
Since I feel like the 2 vulnerabilities are relatively impactful, I've sent the detail and the POC in an email to info@os4ed.com last week. Is that the correct place to report it?
Thanks in advance! | Possible new vulnerabilities in V7.6 | https://api.github.com/repos/OS4ED/openSIS-Classic/issues/158/comments | 3 | 2021-02-22T16:47:11Z | 2021-07-25T01:39:18Z | https://github.com/OS4ED/openSIS-Classic/issues/158 | 813,672,744 | 158 | 2,492 |

`/coreframe/app/promote/admin/index.php:42-60`
```php
public function search() {
$siteid = get_cookie('siteid');
$page = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1;
$page = max($page,1);
$fieldtype = $GLOBALS['fieldtype'];
$keywords = $GLOBALS['keywords'];
if($fieldtype=='place') {
$where = "`siteid`='$siteid' AND `name` LIKE '%$keywords%'";
echo $where;
$result = $this->db->get_list('promote_place', $where, '*', 0, 50,$page,'pid ASC');
$pages = $this->db->pages;
$total = $this->db->number;
include $this->template('listingplace');
} else {
$where = "`siteid`='$siteid' AND `$fieldtype` LIKE '%$keywords%'";

$pages = $this->db->pages;
$total = $this->db->number;
include $this->template('listing');

}
```
The `$fieldtype` parameter is controllable and the direct filtering of the `$keywords` parameter is not rigorous.

`/coreframe/app/order/admin/card.php:21-45`
```php
public function listing() {
$page = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1;
$page = max($page,1);
$batchid = isset($GLOBALS['batchid']) ? $GLOBALS['batchid'] : 0;
$keytype = isset($GLOBALS['keytype']) ? $GLOBALS['keytype'] : 0;
$keywords = isset($GLOBALS['keywords']) ? trim($GLOBALS['keywords']) : '';
$where = $batchid ? "`batchid`='$batchid'" : '';
if($keytype==0 && $keywords) {
$where = "card_no LIKE '$keywords%'";
} elseif($keytype==1 && $keywords) {
$r = $this->db->get_one('member', array('username' => $keywords));
if($r) {
$uid = $r['uid'];
$where = "uid = '$uid'";
} else {
MSG('用户不存在',HTTP_REFERER);
}
}
$result = $this->db->get_list('order_card', $where, '*', 0, 20,$page,'cardid DESC');
$pages = $this->db->pages;
$total = $this->db->number;
$status_arr = array('<b>待发送</b>','未预约','已预约');
include $this->template('card_listing');
}
```
In the `card.php` file, the `$keytype` parameter and the `$keywords` parameter under the `listing` method are controllable, and the `$keywords` parameter is not strictly filtered, causing SQL injection vulnerabilities!

] | Hi,
We found that `static/main-preload.js` introduces dangerous API openShellExternal for arbitrary access on unsafe renderer process.
This may lead to remote command execution.
We suggest that a URL check should be enforced at L15, which enforces an allowlist on trusted URLs.

## Wuzhicms v4.1.0 /coreframe/app/order/admin/index.php hava a SQL Injection Vulnerability
Someone has submitted a `SQL` injection vulnerability in the file `/coreframe/app/order/admin/index.php` before (https://github.com/wuzhicms/wuzhicms/issues/175), but I found that in addition to the `$flag` parameter, it can be injected In addition, the `$keyValue` parameter can also be injected!
## Vulnerability file:
`coreframe/app/order/admin/index.php 22-87`
```php
public function listing() {
load_class('form');
$fieldtypes = array('订单ID','标题','下单会员','物流单号');
$flag = $GLOBALS['flag'];
$status = array();
$status[1] = '待发货';
$status[2] = '已发货';
$status[3] = '订单完成';
$status_arr = $this->status_arr;
$page = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1;
$page = max($page,1);
$keyValue = strip_tags($GLOBALS['keyValue']);
$fieldtype = intval($GLOBALS['fieldtype']);
$where = '1';
if($keyValue) {
switch($fieldtype) {
case 0:
$where .= " AND `order_no`='$keyValue'";
break;
case 1:
$where .= " AND `remark` LIKE '%$keyValue%'";
break;
case 2:
$r = $this->db->get_one('member', array('username' => $keyValue));
$uid = $r['uid'];
$where .= " AND `uid`='$uid'";
break;
case 3:
$where .= " AND `snid`='$keyValue'";
break;
}
}
if($flag!='' && $flag==0 || $flag) $where .=" AND `status`='$flag'";
$starttime = '';
$endtime = '';
if($GLOBALS['starttime']) {
$starttime = strtotime($GLOBALS['starttime']);
$where .= " AND `addtime`>'$starttime'";
}
if($GLOBALS['endtime']) {
$endtime = strtotime($GLOBALS['endtime']);
$where .= " AND `addtime`<'$endtime'";
}
$result_arr = $this->db->get_list('order_point', $where, '*', 0, 20,$page,'orderid DESC');
```
Set `$fieldtype`=1 and `$keyValue` to be controllable.
the `$keyValue`parameter is not strictly filtered, causing `SQL` injection vulnerabilities!
## POC
```

```
```
