Deeper analysis

The WordPress Webinar Plugin – WebinarPress plugin for WordPress is vulnerable to arbitrary file creation due to a missing capability check on the 'sync-import-imgs' function and missing file type validation. The flaw affects all versions up to and including 1.33.24 and carries a CVSS 3.1 score of 8.8.

Authenticated attackers with subscriber-level access or higher can exploit the issue over the network to write arbitrary files on the server, which may be leveraged for remote code execution.

A fix addressing the missing authorization and validation checks is available in the referenced plugin changeset, and the vulnerability is tracked in the Wordfence advisory database.

The EPSS score has remained flat at its peak value of 0.1216 with no material increase observed after disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Enforces approved authorizations, directly addressing the missing capability check on the 'sync-import-imgs' function that allows unauthorized access.

SI-10 Information Input Validation good match
prevent

Validates information inputs such as file types prior to processing, mitigating the absent file type validation that enables arbitrary file creation.

AC-6 Least Privilege partial match
prevent

Restricts user privileges to the least necessary, limiting the impact of exploitation by low-privilege authenticated users like subscribers.
