# CVE-2026-15554: Undertow-core: undertow: authentication bypass via ajp ssl_cert/is_ssl forgery

Status: published. Published: 2026-08-11. Updated: 2026-11-12.

the Undertow AJP listener honours forged ssl_cert and is_ssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP protocol.

## Remediation

- workaround: Restrict direct TCP access to the Undertow AJP listener (default port 8009) so that only trusted reverse proxies can connect, for example by binding the AJP listener to localhost or applying firewall rules that limit access to the port to trusted hosts, since exploitation requires direct network access to the AJP port. Additionally, configure the AJP listener to require a shared secret so that AJP requests without proper authentication are rejected, as the flaw arises because forged ssl_cert and is_ssl attributes are honoured without any shared-secret authentication.
