  • Exploit targets HTTP POST requests to /cwi/ajax_request/get_data.php?store=1 with a fixed URI length of 38 bytes; filter for this exact URI pattern.
  • Command injection payload is injected into the request body via the 'Acsl-interface-tools-traceroute-destination' or 'Acsl-interface-tools-ping-destination' parameters using shell metacharacters: semicolon (;/%3B), newline (\n/%0A), backtick (`/%60), pipe (|/%7C), or dollar sign ($/%24).
  • Exploitation is performed over plaintext HTTP (not TLS); monitor perimeter and internal network segments for unencrypted traffic matching this pattern.
  • Successful exploitation allows arbitrary OS command execution as root via the ping or traceroute field on the TCP/IP screen of the 2wcom IP-4c web interface.
  • ·Exploitation requires authenticated access as an 'admin' or 'manager' role user; unauthenticated exploitation is not indicated by available sources.
  • ·Vulnerability is confirmed on firmware version 2.16 of the 2wcom IP-4c device; other versions are not confirmed affected.
