CVE-2023-46589: Apache Tomcat: HTTP request smuggling via malformed trailer headers
First published: Tue Nov 28 2023(Updated: )
Affected versions: - Apache Tomcat 11.0.0-M1 through 11.0.0-M10 - Apache Tomcat 10.1.0-M1 through 10.1.15 - Apache Tomcat 9.0.0-M1 through 9.0.82 - Apache Tomcat 8.5.0 through 8.5.95 Description: Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly parse HTTP trailer headers. A 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. Users are recommended to upgrade to version 11.0.0-M11 onwards, 10.1.16 onwards, 9.0.83 onwards or 8.5.96 onwards, which fix the issue.
