Description Preview

OpenLiteSpeed versions prior to 1.6.5 contain a vulnerability in the WebAdmin Console where the application does not properly validate request URLs. This improper input validation (CWE-20) is particularly evident in the "Server Configuration > External App" screen, which could potentially allow attackers to manipulate requests in unintended ways.

Overview

The vulnerability affects the WebAdmin Console component of OpenLiteSpeed web server software. The issue stems from insufficient validation of request URLs, which could potentially allow malicious actors to craft special requests that might bypass security controls. The "Server Configuration > External App" screen is specifically identified as demonstrating this vulnerability. This type of improper input validation could potentially lead to various attacks, including unauthorized access to configuration settings or other security issues depending on the implementation details.

Remediation

Users should upgrade OpenLiteSpeed to version 1.6.5 or later, which contains fixes for this vulnerability. System administrators should review their OpenLiteSpeed configurations after upgrading to ensure no unauthorized changes were made to the system. If upgrading is not immediately possible, consider restricting access to the WebAdmin Console to trusted IP addresses only and implement additional network security controls to limit exposure of the management interface.
