- →Exploit requests use HTTP POST method to /cgi-bin/mainfunction.cgi with body parameters: action=commandTable, command=, and parameter= containing OS command injection characters (;, newline, backtick, pipe, $) ↗
- →Injection payload in the 'parameter' POST body field contains shell metacharacters: semicolon (;/%3B), newline (\n/%0A), backtick (`/%60), pipe (|/%7C), or dollar sign ($/%24) — match with PCRE against the parameter value ↗
- →Attack targets DrayTek Vigor2960 web management interface; traffic is expected in plaintext (not TLS), making perimeter and internal network inspection viable ↗
- →Attacker must be authenticated with network access to the web management interface prior to exploitation ↗
- ·This vulnerability only affects DrayTek Vigor2960 v1.5.1.4, a product that is end-of-life and no longer supported by the maintainer; no patch will be issued ↗
- ·Exploitation requires prior authentication; unauthenticated access to the web management interface alone is insufficient to trigger the vulnerability ↗
