  • →Detect base64-encoded PowerShell payloads passed via the search_file_type parameter, specifically the -enc flag combined with -ep bypass -NoLogo -NonInteractive -NoProfile. ↗
  • →Alert on POST requests to /components/user/controller.php?action=authenticate followed shortly by requests to the filemanager search endpoint — this sequence indicates authenticated exploitation. ↗
  • →On Linux targets, look for nc (netcat) pipe to /bin/bash in HTTP POST body parameters, specifically the pattern: newline-encoded nc <ip> <port>|/bin/bash injected into search_file_type. ↗
  • →Detect outbound TCP connections from the web server process (e.g., php-fpm, apache) to arbitrary IPs/ports, consistent with a reverse shell established via TCPClient or nc. ↗
  • →Flag Content-Type: application/x-www-form-urlencoded requests to the Codiad filemanager search endpoint where search_file_type contains %0A, ||, or %22|| sequences. ↗
  • ·The exploit targets Codiad <= 2.8.4 and requires valid credentials (authenticated RCE). The injection point differs between Windows and Linux targets, and also between old vs. new versions of escapeshellarg on Windows — two separate payloads are tried automatically. ↗
  • ·This CVE is distinct from CVE-2017-11366 and CVE-2017-15689, which are prior Codiad RCE vulnerabilities. Detection rules should not conflate these. ↗
