CVE-2022-42252: Apache Tomcat request smuggling via malformed content-length
First published: Tue Nov 01 2022(Updated: )
Apache Tomcat is vulnerable to HTTP request smuggling, caused by the failure to reject a request containing an invalid Content-Length header when configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false. By sending a specially-crafted request, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
