Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for access to system resources, directly mitigating the missing capability check that allows unauthorized data modification and privilege escalation.

AC-6 Least Privilege good match

prevent

Implements the principle of least privilege, ensuring functions like add_capto_img() require appropriate capabilities to prevent unauthenticated attackers from updating arbitrary options.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of flaws such as this plugin vulnerability, preventing exploitation through patching to version beyond 3.11.0.

NVD Description

The Media Manager for UserPro plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the add_capto_img() function in all versions up to, and including, 3.11.0. This…

makes it possible for unauthenticated attackers to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
