Descriptions

When using an OCSP responder Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 did not correctly handle invalid responses. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS. Users not using OCSP checks are not affected by this vulnerability.

Al emplear un respondedor OCSP, Apache Tomcat Native desde la versión 1.2.0 hasta la 1.2.16 y desde la versión 1.1.23 hasta la 1.1.34 no gestionó correctamente las respuestas inválidas. Esto permitió que los certificados de cliente revocados se identificasen erróneamente. Por lo tanto, era posible que los usuarios se autenticasen con certificados revocados al emplear TLS mutuo. Los usuarios que no emplean comprobaciones OCSP no se han visto afectados por esta vulnerabilidad.
