url /imcat/root/tools/adbug/binfo.php?phpinfo1↗

path /imcat/root/tools/adbug/binfo.php↗

• → HTTP GET request to /imcat/root/tools/adbug/binfo.php?phpinfo1 returning HTTP 200 with phpinfo output body strings indicates successful exploitation ↗
• → Response body containing both 'PHP Extension' AND 'PHP Version' strings confirms phpinfo page exposure ↗
• → Extract the PHP version from the response body using regex pattern '>PHP Version ([0-9.]+)' to fingerprint the server ↗

• · The vulnerable path assumes imcat is installed under the /imcat/ web root subdirectory; installations at the web root or other paths will differ ↗
• · Vulnerability is unauthenticated and requires no prior privileges (PR:N, UI:N), making it trivially exploitable from the network ↗
