About

Identifies the SolarWinds Web Help Desk Java process loading an untrusted or remote native module (DLL). This behavior is uncommon for the Web Help Desk server and may indicate successful exploitation of deserialization vulnerabilities (CVE-2025-40536, CVE-2025-40551), which allow attackers to load malicious SQLite extensions and achieve remote code execution.
