Summary
Evolution CMS 3.1.6 contains a remote code execution vulnerability that allows authenticated users with module creation permissions to execute arbitrary system commands by injecting PHP code into module parameters. Attackers can send POST requests to /manager/index.php with malicious PHP code in the 'post' parameter to create modules that execute arbitrary commands when invoked.
Risk Assessment
An authenticated attacker can gain full control over the server, leading to compromise of data confidentiality, integrity, and availability, and enabling further attacks.
Recommendation
Immediately upgrade Evolution CMS to the latest version. Also restrict module creation permissions to trusted users and apply input validation.
