Unauthenticated session ID disclosure via task acquisition

Published Sep 28, 2022 · Updated May 21, 2025

Incorrect authorization in Smart eVision 2022.02.21 allows remote attackers to obtain other general users' session IDs. The task-acquisition function returns session identifiers without verifying that the unauthenticated requester is authorized for the associated user's task. No account or user interaction is required, and the documented impact is limited to disclosure of other general users' session identifiers.
