Apache · Apache Tomcat · CVE-2023-41080
**Name of the Vulnerable Software and Affected Versions**
Apache Tomcat versions 8.5.0 through 8.5.92
Apache Tomcat versions 9.0.0-M1 through 9.0.79
Apache Tomcat versions 10.1.0-M1 through 10.0.12
Apache Tomcat versions 11.0.0-M1 through 11.0.0-M10
**Description**
The issue is related to a URL redirection vulnerability in the FORM authentication feature of Apache Tomcat, which can allow a remote attacker to redirect users to an arbitrary URL. This vulnerability is limited to the ROOT (default) web application. If the ROOT web application is configured to use FORM authentication, a specially crafted URL could be used to trigger a redirect to an URL of the attacker's choice.
**Recommendations**
For Apache Tomcat versions 8.5.0 through 8.5.92, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 9.0.0-M1 through 9.0.79, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 10.1.0-M1 through 10.0.12, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 11.0.0-M1 through 11.0.0-M10, update to a version outside of this range to resolve the issue.
As a temporary workaround, consider disabling the FORM authentication feature in the ROOT web application until a patch is available.
