Summary

Apache Tomcat: Redirect after FORM auth may bypass method specific constraints

Details

Incorrect Authorization vulnerability in Apache Tomcat's FORM authentication process allows the bypassing of a security constraint that limits user has access to a resource POST but not GET.

This issue affects Apache Tomcat: from 11.0.0 through 11.0.24, from 10.1.0 through 10.1.57, from 9.0.0 through 9.0.120.

The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected.

Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fixes the issue.
