Authenticated privilege escalation via profile update

Published Sep 19, 2022 · Updated May 29, 2025

Improper privilege management in Suprema BioStar 2 2.8.16 allows remote authenticated users to gain System Administrator access. The update-profile API accepts a crafted PUT request from a User Operator without enforcing the account-level authorization boundary. User Operator credentials are required, after which the account gains unrestricted administrative control over the BioStar 2 server.
