CVE-2025-66571
CriticalSummary
UNA CMS versions 9.0.0-RC1 through 14.0.0-RC4 contain a PHP object injection vulnerability in BxBaseMenuSetAclLevel.php where the profile_id POST parameter is passed to PHP unserialize() without proper handling, allowing remote, unauthenticated attackers to inject arbitrary PHP objects and potentially write and execute arbitrary PHP code.
Risk Assessment
An unauthenticated attacker can execute arbitrary PHP code on the server, potentially leading to full system compromise and data access.
Recommendation
Update UNA CMS to a version that includes a fix. Additionally, sanitize input parameters before passing to unserialize() and consider using safer deserialization methods.
