CVE-2014-0227: java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat 6.x before 6.0.42, 7.x befor...

Security readout for executives and security teams

Older Apache Tomcat releases mishandled malformed chunked HTTP request bodies after an error. An unauthenticated remote attacker could use that parser confusion for HTTP request smuggling or resource-consumption denial of service. The main business risk is exposed legacy Tomcat handling internet traffic, especially behind proxies or load balancers. Exposure is likely where legacy Tomcat 6, 7, or early 8 instances are still reachable over HTTP/S. Systems packaged by Linux vendors or bundled in Oracle, HP, or other products may also be affected if they shipped vulnerable Tomcat versions. Treat this as a legacy internet-facing middleware risk. Patch or remove affected Tomcat urgently where exposed to untrusted traffic, because request smuggling can undermine perimeter assumptions and denial of service can affect availability. Mitigation focus: Upgrade Tomcat to 6.0.42, 7.0.55, 8.0.9, or later supported releases.; Apply relevant vendor security updates for packaged or embedded Tomcat deployments.; Check vendor advisories for bundled products that include Tomcat..
