Detection Guidance

This vulnerability involves the /cgi-bin/tools/ajax_cmd endpoint on Panabit PAP-XM320 devices, which allows authenticated users to execute arbitrary shell commands with root privileges via the action=runcmd parameter.

To detect this vulnerability on your system, you can monitor HTTP requests targeting the /cgi-bin/tools/ajax_cmd endpoint, especially those containing the action=runcmd parameter.

Suggested commands include using network monitoring tools or web server logs to search for suspicious requests. For example, using grep on web server logs:

• grep "/cgi-bin/tools/ajax_cmd" /var/log/httpd/access_log
• grep "action=runcmd" /var/log/httpd/access_log

Additionally, you can use network traffic analysis tools like tcpdump or Wireshark to filter HTTP requests to the vulnerable endpoint.

Mitigation Strategies

Immediate mitigation steps include restricting access to the /cgi-bin/tools/ajax_cmd endpoint to trusted and authenticated users only.

Ensure that only authorized personnel have authentication credentials to the device, and consider disabling or restricting the vulnerable CGI component if possible.

Monitor logs and network traffic for any suspicious activity targeting this endpoint.

Contact the vendor or check their official website for any patches or updates that address this vulnerability.
