Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Learn more on MITRE.
