Description

Detection of Error Condition Without Action vulnerability in Apache Tomcat when configuring Certificate Revocation List (CRLs) for a FFM based connector. If an FFM connector was configured with invalid CRLs, the invalid CRLs were ignored meaning invalid certificates could be accepted. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.22, from 10.1.0-M7 through 10.1.55, from 9.0.83 through 9.0.118. Users are recommended to upgrade to version 11.0.23, 10.1.56 or 9.0.119, which fixes the issue.
