This vulnerability in Cyber-III Student-Management-System up to commit 1a938fa61e9f735078e9b291d2e6215b4942af3f involves improper validation in the move_uploaded_file function within the upload.php script. An attacker can remotely manipulate the File parameter to upload arbitrary files without restriction. The issue was reported early but remains unpatched, with no official remediation available. The product uses rolling releases, so fixed versions are not clearly delineated. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and low impacts on confidentiality, integrity, and availability.

Successful exploitation allows remote attackers with low privileges to upload arbitrary files to the server, potentially leading to unauthorized file placement. The impact on confidentiality, integrity, and availability is rated low, but unrestricted upload can facilitate further attacks such as web shell deployment or defacement. No known active exploitation in the wild has been reported yet.

No official fix or patch is currently available from the vendor. Since the vendor has not responded and no remediation level is provided, users should monitor the vendor advisory for updates. Until a patch is released, consider implementing manual controls such as restricting upload file types, validating file inputs, or isolating the upload functionality to minimize risk.
