The ABB Cylon controller suffers from an authenticated path traversal vulnerability. This can be exploited through the 'devName' POST parameter in the ethernetUpdate.php script to write partially controlled content, such as IP address values, into arbitrary file paths, potentially leading to configuration tampering and system compromise including denial of service scenario through ethernet configuration backup file overwrite.

Mirai and Keksec botnet variants are exploiting critical vulnerabilities in D-Link routers. Learn about the impact, affected devices, and how to protect yourself from these attacks.

The ABB BMS/BAS controller suffers from an authenticated blind OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'variant' HTTP POST parameter called by the clearProjectConfigurationAjax.php script.

The ABB BMS/BAS controller suffers from an authenticated blind OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'instance' HTTP POST parameter called by calendarUpdate.php script.

The ABB BMS/BAS controller suffers from an authenticated reflected cross-site scripting vulnerability. Input passed to the GET parameter 'name' is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML/JS code in a user's browser session in context of an affected site.

### Impact The malicious user is able to commit and edit a crafted symlink file to a repository to gain SSH access to the server. ### Patches Editing symlink while changing the file name has been prohibited via the repository web editor (https://github.com/gogs/gogs/pull/7857). Users should upgrade to 0.13.1 or the latest 0.14.0+dev. ### Workarounds No viable workaround available, please only grant access to trusted users to your Gogs instance on affected versions. ### References n/a ### Proof of Concept 1. Create two repositories, upload something to the first repository, edit any file, and save it on the webpage. 2. In the second repository, create a symbolic link to the file you need to edit: ```bash $ ln -s /data/gogs/data/tmp/local-repo/1/.git/config test $ ls -la total 8 drwxr-xr-x   5 dd  staff  160 Oct 27 19:09 . drwxr-xr-x   4 dd  staff  128 Oct 27 19:06 .. drwxr-xr-x  12 dd  staff  384 Oct 27 19:09 .git -rw-r--r--   1 dd  staff   12 O...

The ABB BMS/BAS controller suffers from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through POST parameters, including REMOTE, IP1, IP2, IP3, IP4, and NAME, called by the syslogUpdate.php script.

### Summary An **Improper URL Handling Vulnerability** allows an attacker to access sensitive local files on the server by exploiting the `file:///` protocol. This vulnerability is triggered via the **"real-browser"** request type, which takes a screenshot of the URL provided by the attacker. By supplying local file paths, such as `file:///etc/passwd`, an attacker can read sensitive data from the server. ### Details The vulnerability arises because the system does not properly validate or sanitize the user input for the URL field. Specifically: 1. The URL input (`<input data-v-5f5c86d7="" id="url" type="url" class="form-control" pattern="https?://.+" required="">`) allows users to input arbitrary file paths, including those using the `file:///` protocol, without server-side validation. 2. The server then uses the user-provided URL to make a request, passing it to a browser instance that performs the "real-browser" request, which takes a screenshot of the content at the given URL....
