Privilege escalation via exposed administrator session cookies
Published Jan 24, 2020 · Updated Aug 5, 2024
Information disclosure in Big Switch Big Monitoring Fabric 6.2 through 7.1.3 allows remote authenticated users to obtain administrator session cookies via an API. The API endpoint returns session-cookie values belonging to authenticated administrators when queried by a read-only account, exposing credentials that can be replayed as those administrators. The attack requires network access and read-only authentication; successful cookie use enables privilege escalation and access to administrator-authorized functions.
