The update was not correct. As a result, some scripts may have failed to execute as expected and other scripts may have been executed unexpectedly. Note that the behaviour of the CGI servlet has remained unchanged in this regard. It is only the documentation of the behaviour that was wrong and has been corrected. Mitigation: Users of the affected versions should review the CGI documentation from one of the following versions and ensure that the described CGI search algorithm matches their expectation: - - Apache Tomcat 9.0.2 or later - - Apache Tomcat 8.5.24 or later - - Apache Tomcat 8.0.48 or later - - Apache Tomcat 7.0.84 or later (Apache Tomcat 7.0.83 has the fix but was not released) Credit: This issue was reported responsibly to the Apache Tomcat Security Team by Michael Grenier.
