The Apache Foundation has announced CVE-2018-11784, a flaw in multiple versions of the popular Tomcat server that can be used to cause a redirect to be generated to any URI of the attacker’s choice. The flaw was discovered and reported to the Apache Foundation by an independent security researcher.

Apache Tomcat 9.0.0.M1 to 9.0.11, Apache Tomcat 8.5.0 to 8.5.33, and Apache Tomcat 7.0.23 to 7.0.90 are vulnerable and an unsupported Tomcat 8.0.x release line has not been analyzed, but is likely to be affected.

Full details are available from The Apache Foundation.
