Authentication Bypass in SolarWinds Web Help Desk
CVE-2025-40552 is a critical authentication bypass vulnerability in SolarWinds Web Help Desk (WHD). According to the provided content, the flaw allows a remote attacker to execute actions and methods that are intended to be protected by authentication. More specifically, watchTowr’s analysis describes it as a pre-authentication issue that permits direct invocation of WebObjects components without following the expected application hierarchy, allowing access to otherwise authenticated functionality. The issue affects SolarWinds Web Help Desk versions prior to 2026.1, including 12.8.8 Hotfix 1 and below. The vulnerability is also described as chainable with other WHD flaws, particularly deserialization issues such as CVE-2025-40553, to reach pre-authentication remote code execution.
