Summary

Ella Core has Privilege Escalation via Database Restore by NetworkManager role

Details

Summary

The NetworkManager role was granted backup and restore permission. The restore endpoint accepted any valid SQLite file without verifying its contents.

Impact

A NetworkManager could replace the production database with a tampered copy to escalate to Admin, gaining access to user management, audit logs, debug endpoints, and operator identity configuration that the role was explicitly denied.

Fix

Backup and restore permissions have been removed from the NetworkManager role.

Severity

7.2 (High)

Title

Ella Core has Privilege Escalation via Database Restore by NetworkManager role

Summary

Ella Core is a 5G core designed for private networks. Prior to version 1.7.0, the NetworkManager role was granted backup and restore permission. The restore endpoint accepted any valid SQLite file without verifying its contents. A NetworkManager could replace the production database with a tampered copy to escalate to Admin, gaining access to user management, audit logs, debug endpoints, and operator identity configuration that the role was explicitly denied. In version 1.7.0, backup and restore permissions have been removed from the NetworkManager role.

Severity
