Recommendation: Monitor — no exploitation signal at the moment.

Gila CMS versions prior to 2.0.0 contain a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary system commands through manipulated HTTP headers. Attackers can inject PHP code in the User-Agent header with shell_exec() to run system commands by sending crafted requests to the admin endpoint.
