CVE-2019-25687
Pegasus CMS 1.0 contains a remote code execution vulnerability in the extra_fields.php plugin that allows unauthenticated attackers to execute arbitrary commands by exploiting unsafe eval functionality. Attackers can send POST requests to the submit.php endpoint with malicious PHP code in the action parameter to achieve code execution and obtain an interactive shell.
