Authenticated route hijacking via malformed HAProxy entry
Published Sep 1, 2022 · Updated Aug 3, 2024
OpenShift Container Platform 3.11 and 4.6 onward allows remote authenticated users with Route permissions to redirect traffic. Crafted Route data inserts a malformed HAProxy configuration entry that matches arbitrary hostnames and forwards requests to an attacker-controlled application. Exploitation requires permission to create or modify Routes; the consequence is traffic hijacking with confidentiality and integrity impact.
