Associated Vulnerability

Title:SolarWinds Web Help Desk Deserialization of Untrusted Data Remote Code Execution Vulnerability (CVE-2025-40551)
Description:SolarWinds Web Help Desk was found to be susceptible to an untrusted data deserialization vulnerability that could lead to remote code execution, which would allow an attacker to run commands on the host machine. This could be exploited without authentication.

Description

SolarWinds Web Help Desk before version 2026.1 contains an insecure deserialization vulnerability in the jabsorb JSON-RPC library. When chained with a CSRF whitelist bypass (CVE-2025-40536), remote unauthenticated attackers can exploit JNDI injection via the Apache Xalan JNDIConnectionPool class to achieve remote code execution. The bypass involves including "/ajax/" in a query parameter to circumvent URI validation, while switching from "/ajax/" to "/wo/" endpoints bypasses payload sanitization routines.
