The Network Analysis tab (Main_Analysis_Content.asp) in the ASUS RT-AC68U and other RT series routers with firmware before 3.0.0.4.374.5047 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the Target field (destIP parameter).

  • Monitor HTTP GET requests to /apply.cgi targeting Main_Analysis_Content.asp with shell metacharacters (e.g., semicolons, encoded as %3B) in the destIP parameter, indicating command injection attempts.
  • Look for the Referer header value 'http://192.168.1.1/Main_Analysis_Content.asp' combined with injection payloads in the destIP query parameter in HTTP logs.
  • Detect URL-encoded semicolons (%3B) or shell command sequences (e.g., ls, wget, curl) within the destIP or SystemCmd parameters of requests to /apply.cgi.
  • The exploit uses a default credential Base64 value 'ZGVmYXVsdA==' (decodes to 'default') in the Authorization header; alert on Basic auth with this value against router management interfaces.
  • ·Vulnerability only affects authenticated users; exploitation requires valid credentials to the router's web management interface.
  • ·Affected firmware versions are below 3.0.0.4.374.5047; devices running firmware at or above this version are patched.
