MetInfo CMS versions 7.9, 8.0, and 8.1 contain an unauthenticated PHP code injection vulnerability that allows remote attackers to execute arbitrary code by sending crafted requests with malicious PHP code. Attackers can exploit insufficient input neutralization in the execution path to achieve remote code execution and gain full control over the affected server.
