Executive Summary

This vulnerability affects the Mindstien Quick Login WordPress plugin version 1.0 or below. It allows unauthenticated attackers to take over an administrator account by exploiting improper validation of the 'mql_pass' parameter in requests. The flaw bypasses authentication by not verifying if the request value matches the user's session.

Detection Guidance

Check if the Mindstien Quick Login WordPress plugin version 1.0 or below is installed on your system. Look for unauthorized administrator account access or unusual session activity. Monitor requests containing the 'mql_pass' parameter for suspicious values.

Impact Analysis

An attacker could gain administrator-level access to your WordPress site without credentials. This could lead to full site takeover, unauthorized changes, data theft, or installation of malicious plugins.

Compliance Impact

This vulnerability allows unauthenticated attackers to gain administrator access to a WordPress site, potentially exposing sensitive user data. This could lead to violations of GDPR (data protection) and HIPAA (health information privacy) if personal or health data is compromised. Unauthorized access may result in data breaches, unauthorized processing, or disclosure of regulated information.

Mitigation Strategies

Immediately uninstall or disable the Mindstien Quick Login WordPress plugin if installed. Restrict administrator account access and review user sessions for signs of compromise. Monitor network traffic for unusual requests targeting the 'mql_pass' parameter.
