Testing Methodology
Validate this detection against 3 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-2025-54068 Basic eval() Injection via Livewire Message Endpoint
Expected signal: HTTP POST to /livewire/message with base64-encoded payload containing system() call; PHP process may log eval() warning; web server logs capture anomalous request body.
- Test 2CVE-2025-54068 Shell Command Execution via Livewire Injection
Expected signal: Process creation event: php or php-fpm spawning /bin/sh with argument 'id > /tmp/pwned'; file creation event at /tmp/pwned; web server access log entry for the crafted POST.
- Test 3CVE-2025-54068 Webshell Deployment Simulation
Expected signal: File creation event for shell.php in public/ directory initiated by php-fpm or web server process; subsequent HTTP GET requests to /shell.php with command parameters.
