Fixed in Apache Tomcat 10.0.21

Low: Apache Tomcat EncryptInterceptor DoS CVE-2022-29885

The documentation for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks.

This was fixed with commit 36826ea6.

This issue was reported to the Apache Tomcat Security team by 4ra1n on 17 April 2022. The issue was made public on 10 May 2022.

Affects: 10.0.0-M1 to 10.0.20
