Executive Summary

This vulnerability exists in the WeGIA web manager for charitable institutions prior to version 3.6.5. It is a critical Remote Code Execution (RCE) flaw in the application's database restoration functionality. An attacker who has administrative access can exploit this by uploading a backup file with a specially crafted filename, which allows them to execute arbitrary operating system commands on the server.

Administrative access can be obtained through a previously reported Authentication Bypass vulnerability, making this RCE vulnerability particularly dangerous.

The issue is fixed in version 3.6.5 of WeGIA.
