This allowed for revoked client certificates to be incorrectly identified.
HIGH 7.4EPSS 4.07%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
