CVE-2025-3593Public exploitNetwork attack vector

Authenticated arbitrary file upload via unchecked file type

Published Apr 14, 2025 · Updated Apr 15, 2025

Unrestricted file upload in MyBlog-layui 1.0 allows remote authenticated users to place executable JSP content through authorImg. The AdminController Upload handler accepts the multipart File value without restricting file type, including a JSP payload labeled image/jpeg. A valid administrative session is required; requesting the stored JSP executes attacker-controlled code with application-process privileges.
