h4. Open redirect in default servlet [CVE-2018-11784|https://access.redhat.com/security/cve/cve-2018-11784]

When the default servlet in Apache Tomcat versions 9.0.0.M1 to 9.0.11, 8.5.0 to 8.5.33 and 7.0.23 to 7.0.90 returned a redirect to a directory (e.g. redirecting to ‘/foo/’ when the user requested ‘/foo’) a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.

Fixed versions:

  • >=9.0.12

  • >=8.5.34

  • >=7.0.91

Workaround:
{quote}Use mapperDirectoryRedirectEnabled=“true” and mapperContextRootRedirectEnabled=“true” on the Context to ensure that redirects are issued by the Mapper rather than the default Servlet. See the Context configuration documentation for further important details.
