Published May 23, 2025 · Updated Apr 28, 2026

Unrestricted file upload in joy2012bd JP Students Result Management System Premium 1.1.7 allows remote attackers to upload web shells. The plugin's upload handling accepts attacker-supplied files without file-type validation, but public records do not identify the endpoint or function. No authentication or user interaction is required, and an uploaded server-executable file grants code execution under the web server account.
