Vulnerability Overview

The POST SMTP Mailer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.5.6. This is due to incorrect nonce validation on the delete_logs_ajax() function. This makes it possible for unauthenticated attackers to delete logs granted they can trick a site user with the manage_postman_smtp capability into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 2.5.7, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
