Apache Tomcat Rewrite rule bypass

Quick fix

GHSA-ff77-26x5-69cr — org.apache.tomcat:tomcat-catalina: upgrade to the fixed version with the command below.

# pom.xml: bump <version>9.0.104</version> for org.apache.tomcat:tomcat-catalina

Details

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. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.

Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6, which fix the issue.
