At a glance
CVE-2023-3325 is a high-severity Insufficient Verification of Data Authenticity vulnerability in the CMS Commander WordPress plugin, affecting versions <= 2.287. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.288; sites on affected versions should update now. Disclosed June 2023, reported by István Márton.
Vulnerability Overview
The CMS Commander plugin for WordPress is vulnerable to authorization bypass due to the use of an insufficiently unique cryptographic signature on the 'cmsc_add_site' function in versions up to, and including, 2.287. This makes it possible for unauthenticated attackers to the plugin to change the '_cmsc_public_key' in the plugin config, providing access to the plugin's remote control functionalities, such as creating an admin access URL, which can be used for privilege escalation. This can only be exploited if the plugin has not been configured yet, however, if combined with another arbitrary plugin installation and activation vulnerability, the impact can be severe.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-345: Insufficient Verification of Data Authenticity
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
Remediation
Update to version 2.288, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: CMS Commander 2.288 closes this, and updating the plugin is the step that ends it.
