What the vulnerability does
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 in all versions up to, and including, 1.33.24. This makes it possible for authenticated attackers, with subscriber-level access and above, to create arbitrary files that can lead to remote code execution.
Explanation of Vulnerability in Simple Terms
WebinarPress versions up to 1.33.24 lack proper authorization checks, allowing authenticated users with low privileges to read, modify, or delete sensitive webinar data and settings. An attacker with a basic user account can perform actions restricted to administrators. Update to a version newer than 1.33.24 to resolve this issue.
What an attacker can do
Read, modify, or delete webinar data and settings without proper authorization.
Potential impact on your site
Webinar data, attendee information, and plugin settings can be compromised by any authenticated user.
Conditions required to exploit
Attacker must have a low-privilege WordPress user account (e.g., subscriber or contributor).
