II. Public POCs for CVE-2025-40551
| # | POC Description | Source Link | Shenlong Link |
|---|---|---|---|
| 1 | 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. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2025/CVE-2025-40551.yaml | POC Details |
