• → Look for shell metacharacters (e.g. semicolons) injected into the 'f' parameter of the 'filediff' endpoint, particularly referencing CVSROOT/rcsinfo, as this is the injection vector for CVE-2004-1456. ↗
• → Monitor HTTP requests to the 'filediff' endpoint containing semicolons or other shell metacharacters in query string parameters (v1, v2, f), as demonstrated by the PoC payload 'v2=1.2;last;'. ↗

• · The vulnerability is exploited via the 'filediff' CGI endpoint in CVStrac; ensure web server logs capture full query strings for this endpoint to enable post-incident analysis. ↗
