Vulnerability Overview

The Backup and Staging by WP Time Capsule plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.22.20. This is due to wptc_decode_auth_token() function using a loose comparison. This makes it possible for unauthenticated attackers to bypass authentication and access user accounts, including those that may have administrative access. This vulnerability does require a site to have a connection to wptimecapsule.com in order to be exploited.

Technical Analysis

REMEDIATION: Update to version 1.22.21, or a newer patched version --- IDENTIFIER: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) The product requires authentication, but the product has an alternate path or channel that does not require authentication.
