Testing Methodology
Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1CVE-2025-32432 PHP Info Probe via Craft CMS Action Endpoint
Expected signal: HTTP POST to /actions/test with 'phpinfo()' in request body; web server access log entry; potential 200 response with PHP environment disclosure
- Test 2CVE-2025-32432 Base64-Encoded Command Injection
Expected signal: HTTP POST to /actions/users/login with 'base64_decode' in POST body; web server log capturing encoded payload; potential process spawn of 'id' command from php parent
- Test 3CVE-2025-32432 Webshell Drop via File Write Injection
Expected signal: POST to /actions/ with file_put_contents payload; new file 'shell.php' created in web root with anomalous timestamp; subsequent GET to /shell.php with cmd parameter; process execution of 'id' spawned from PHP
- Test 4CVE-2025-32432 Reverse Shell Payload Simulation
Expected signal: HTTP POST to Craft CMS action endpoint with bash reverse shell command in body; outbound TCP connection from web server to attacker IP on port 4444; process tree showing bash spawned from php parent; network flow anomaly for web server initiating outbound connection
