UNA CMS 14.0.0-RC - PHP Object Injection

ID: CVE-2025-32101

Severity: critical

Author: iamnoooob,rootxharsh,pdresearch

Tags: cve,cve2025,una-cms,php,rce

Description

Section titled “Description”

The vulnerability is located in the /template/scripts/BxBaseMenuSetAclLevel.php script. Specifically, within the BxBaseMenuSetAclLevel::getCode() method. When calling this method, user input passed through the “profile_id” POST parameter is not properly sanitized before being used in a call to the unserialize() PHP function. This can be exploited by remote, unauthenticated attackers to inject arbitrary PHP objects into the application scope, allowing them to perform a variety of attacks, such as writing and executing arbitrary PHP code.
