CVE-2025-3842Public exploitNetwork attack vector

Authenticated remote code execution via unrestricted JSP upload

Published Apr 21, 2025 · Updated Apr 22, 2025

Arbitrary file upload in panhainan DS-Java 1.0 allows remote authenticated users to execute JSP code through the profile avatar endpoint. FileUpload.java accepts fileUpload without checking its extension and writes it with FileOutputStream beneath a web-accessible server path. A valid session and profile-update access are required; requesting the uploaded JSP executes attacker-supplied server commands.
