Rational Lifecycle Integration Adapters
Apache Tomcat is vulnerable to HTTP request smuggling and is supplied with
specific versions of Rational Lifecycle Integration Adapter for HP ALM.
DESCRIPTION: Apache Tomcat is vulnerable to HTTP request smuggling. A remote
attacker could send a specially-crafted request in a malformed chunked header
to the Web server to cause multiple processing conflicts on the servers. An
attacker could exploit this vulnerability to poison the web cache, bypass web
application firewall protection, and conduct XSS attacks.
