CVE-2024-37082Network attack vector

Unauthenticated mTLS bypass via crafted HTTP requests

Published Jul 3, 2024 · Updated Aug 2, 2024

Authentication bypass in affected Cloud Foundry deployments allows remote attackers to reach applications protected by mutual TLS. Cloud Foundry has not published the exact request-processing error; its advisory identifies crafted HTTP requests traversing enabled route services while HAProxy forwards client certificates only for route-service traffic. Exposure requires Routing Release before 0.299.0, HAProxy Release above 10.6.0, enabled route services, and forwarded_client_cert set to forward_only_if_route_service.
