Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. For a subset of unlikely rewrite rule configurations, it was possible for a specially crafted request to bypass some rewrite rules. If those rewrite rules effectively enforced security constraints, those constraints could be bypassed. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.5, from 10.1.0-M1 through 10.1.39, from 9.0.0.M1 through 9.0.102. Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.
I was not able to hack the Axon Ivy Platform according to the description of this CVE - as we do not use Tomcat Rewrite Rules. Nevertheless, we are going to update Apache Tomcat with LTS 10.0.28, LTS 12.0.6 and LE 13.1.0.
