Detection & IOCsextracted from sources · hover to see the quote
- →Exploit sends a GET request to /cgi-bin/downloadFlile.cgi with a shell command injection payload in the 'payload' query parameter (QUERY_STRING). Look for backtick-wrapped OS commands in this parameter. ↗
- →Successful exploitation results in a file being written to the web root; a follow-up GET request to the created file returns HTTP 200 with Content-Type: application/octet-stream and directory listing artifacts (.sh, .cgi filenames) in the body. ↗
- →The vulnerability is unauthenticated (no session/auth required). Any GET request to the vulnerable endpoint with a command in the payload parameter should be treated as an attack attempt. ↗
- ·Affects only TOTOLink A950RG firmware versions V5.9c.4050_B20190424 and V4.1.2cu.5204_B20210112. Detection rules should be scoped to these specific firmware versions to reduce false positives. ↗
