url/index.php?page=/etc/passwd%00

  • Look for GET requests to /index.php with a 'page' parameter containing path traversal sequences or null bytes (e.g., ?page=/etc/passwd%00), indicating LFI exploitation attempts.
  • Detect responses containing 'root:.*:0:0:' in the HTTP body, which indicates successful /etc/passwd disclosure via LFI.
  • Use Shodan/FOFA queries to identify exposed Car Rental Management System instances: Shodan: http.html:"car rental management system", FOFA: body="car rental management system".
  • ·The LFI payload uses a null byte (%00) to truncate the filename. This technique is only effective on PHP installations where null byte injection is not mitigated (typically PHP < 5.3.4). Verify target PHP version before assuming exploitability.
  • ·The vulnerability is exploitable by unauthenticated users, meaning no session or credential is required to trigger the LFI.
