  • Detect exploitation attempts by matching HTTP POST requests to the vulnerable licenses.php endpoint with a body containing shell metacharacters in the 'package' parameter (e.g., semicolons used for command injection).
  • Successful exploitation responses will contain all four strings in the body: '"license":', '"name":', 'uid=', and 'gid=' — indicating OS command output (id command) embedded in the JSON response.
  • Identify WAGO devices exposed on the internet using Shodan by searching for HTML content containing '/wbm/' and 'wago'.
  • Identify WAGO devices exposed on the internet using FOFA by searching for body content containing '/wbm/' and 'wago'.
  • The vulnerability is unauthenticated — no session cookie or Authorization header is required in the exploit request. Monitor for POST requests to /wbm/ paths from unauthenticated sources.
  • ·The path segment 'pfcXXX' in the vulnerable URL is a placeholder representing multiple WAGO PFC device variants; actual exploitation paths may vary by specific device model (e.g., pfc100, pfc200).
  • ·The CVE affects multiple WAGO products; the CPE listed covers Compact Controller 100 firmware but the vulnerability scope is broader across WAGO product lines.
