Ventem e-School Arbitrary File Upload Vulnerability Allowing Remote Code Execution

Vulnerability

A vulnerability allowing arbitrary file upload has been identified in the e-School platform by Ventem. This issue enables unauthenticated remote attackers to upload and execute web shell backdoors, facilitating arbitrary code execution on the server. The vulnerability arises from insufficient validation of uploaded files, allowing malicious scripts to be executed on the server.
