Detailsinfo

A vulnerability classified as very critical has been found in Zenitel Connect up to 1.10.x. Affected is an unknown code block of the component JWT Verification. The manipulation of the argument sub with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The pREST database REST API in Zenitel Connect firmware before 1.11.0 signs and verifies JWTs with the platform CA private key, which is stored on a data volume shared between containers, and sets the PostgreSQL session role from the unvalidated sub claim of each request while connected to the database as the "postgres" superuser, which allows local attackers who can read the platform CA private key from the container filesystem to execute database operations as the PostgreSQL superuser, including reading the master encryption key and password hashes, via a forged JWT with sub=postgres sent to the pREST API.
