SecurityTracker Alert ID:  1033132
SecurityTracker URL:  http://securitytracker.com/id/1033132
CVE Reference:   CVE-2014-0227   (Links to External Site)
Date:  Jul 30 2015
Impact:   Denial of service via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 6.1.x prior to 6.1.20.1
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. Blue Coat Director 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:   Blue Coat Systems has issued a fix for Blue Coat Director (6.1.20.1).
