other cmd↗

• → Look for unauthenticated HTTP requests targeting /exec_raw.php with a 'cmd' query parameter — any such request is indicative of exploitation attempts against CVE-2010-20059. ↗
• → PHP/Meterpreter reverse shell payloads are the preferred post-exploitation tool per the Metasploit module; monitor for outbound connections following requests to exec_raw.php. ↗
• → Affected versions are FreeNAS 0.7.2 prior to revision 5543; identify unpatched instances via banner/version enumeration and prioritize for patching or network isolation. ↗

• · The vulnerability is unauthenticated — no credentials are required to reach exec_raw.php, meaning network-level access to the web interface port alone is sufficient for exploitation. ↗
