Published: Translated: NVD NIST

Summary

The Open eClass platform before version 4.2 contains an arbitrary file upload vulnerability in the theme import functionality. An attacker with administrative privileges can upload arbitrary files to the server because files inside the ZIP archive are not validated or sanitized. This leads to remote code execution on the web server. Version 4.2 patches the issue.

Risk Assessment

Risk of server takeover by an administrator, potentially leading to full system and data compromise.

Recommendation

Update Open eClass to version 4.2 or later to eliminate the vulnerability.

Original NVD description (English source)

The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, an arbitrary file upload vulnerability in the theme import functionality enables an attacker with administrative privileges to upload arbitrary files on the server's file system. The main cause of the issue is that no validation or sanitization of the file's present inside the zip archive. This leads to remote code execution on the web server. Version 4.2 patches the issue.
