CVE-2023-46589 Apache Tomcat - Request Smuggling

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected:
Apache Tomcat 11.0.0-M1 to 11.0.0-M10
Apache Tomcat 10.1.0-M1 to 10.1.15
Apache Tomcat 9.0.0-M1 to 9.0.82
Apache Tomcat 8.5.0 to 8.5.95

Description:
Tomcat did not correctly parse HTTP trailer headers. A specially crafted
trailer header that exceeded the header size limit could cause Tomcat to
treat a single request as multiple requests leading to the possibility
of request smuggling when behind a reverse proxy.

Mitigation:
Users of the affected versions should apply one of the following
mitigations:
- Upgrade to Apache Tomcat 11.0.0-M11 or later
- Upgrade to Apache Tomcat 10.1.16 or later
- Upgrade to Apache Tomcat 9.0.83 or later
- Upgrade to Apache Tomcat 8.5.96 or later
