### Summary There is a vulnerability in `Joplin-desktop` that leads to remote code execution (RCE) when a user clicks on an `<a>` link within untrusted notes. The issue arises due to insufficient sanitization of `<a>` tag attributes introduced by the `Mermaid`. This vulnerability allows the execution of untrusted HTML content within the Electron window, which has full access to Node.js APIs, enabling arbitrary shell command execution. ### Details In the markdown preview iframe, `Joplin` only opens `<a>` links internally within the same Electron window if they contain the `data-from-md` attribute. While Joplin successfully sanitizes the `data-from-md` attribute in user-embedded `<a>` links from the `.md` file to prevent the execution of untrusted HTML content, it fails to sanitize the `data-from-md` attributes of `<a>` tags introduced by `Mermaid` (e.g., the code snippet shown below). Since `Mermaid` allows the rendering of certain scriptless HTML elements, an attacker can embed `<a>...

Multiple threat actors have been found taking advantage of an attack technique called Sitting Ducks to hijack legitimate domains for using them in phishing attacks and investment fraud schemes for years. The findings come from Infoblox, which said it identified nearly 800,000 vulnerable registered domains over the past three months, of which approximately 9% (70,000) have been subsequently

### Impact s2n-tls uses the Linux atexit function to register functions that clean up the global state when the process exits. In multi-threaded environments, the atexit handler may clean up state which is still in use by other threads. When this occurs, the exiting process may experience a segmentation fault or other undefined behavior. Customers of AWS services do not need to take action. Applications using s2n-tls should upgrade to the most recent release of s2n-tls. **Impacted versions**: < v1.5.9. ### Patches The patch commit [493b771](https://github.com/aws/s2n-tls/commit/493b77167dc367c394de23cfe78a029298e2a254) is included in s2n-tls v1.5.9 [1] ### Workarounds The atexit handler may be disabled by calling `s2n_disable_atexit()` prior to initializing s2n-tls. The atexit handler is off by default in the patched versions.

Proof of concept remote code execution exploit for PHP-CGI that affects versions 8.1 before 8.1.29, 8.2 before 8.2.20, and 8.3 before 8.3.8.

This is a bash script that is a vulnerability checker for CVE-2024-4577 designed to scan multiple domains for an argument injection vulnerability in PHP-CGI. This tool allows security researchers and system administrators to quickly assess whether their systems or a list of domains are potentially vulnerable to this specific security issue. This issue affected PHP-CGI versions 8.1 before 8.1.29, 8.2 before 8.2.20, and 8.3 before 8.3.8.
