CVE Reference:   CVE-2014-0227   (Links to External Site)
Date:  Jul 7 2015

Description:   A vulnerability was reported in Apache Tomcat. A remote user may be able to conduct HTTP request smuggling attacks against web-based applications on the target system. IBM Cognos Metrics Manager is affected.

A remote user can submit a specially crafted request to trigger a flaw in 'java/org/apache/coyote/http11/filters/ChunkedInputFilter.java' and cause the Apache Tomcat server to read part of the request as a new request. This allows the remote user to embed a request within another request and modify data or cause denial of service on the target system.

Impact:   A remote user may be able to cause an application to incorrectly process the connection and modify data or cause denial of service conditions.
Solution:   IBM has issued an advisory for IBM Cognos Metrics Manager.

The IBM advisory is available at:
