Vulnerability from variot

The Cisco Content Services Switch (CSS) 11500 with software 8.20.4.02 and the Application Control Engine (ACE) 4710 with software A2(3.0) do not properly handle LF header terminators in situations where the GET line is terminated by CRLF, which allows remote attackers to conduct HTTP request smuggling attacks and possibly bypass intended header insertions via crafted header data, as demonstrated by an LF character between the ClientCert-Subject and ClientCert-Subject-CN headers. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1576. This vulnerability CVE-2010-1576 Due to an incomplete fix.Through a specially crafted header data by a third party, HTTP A request smuggling attack may be performed and intended header insertion may be avoided. The Cisco CSS 11500 Content Services Switch is a load balancing device that provides robust and scalable network services (layers 4-7) for the data center. An attacker can exploit these issues to impersonate other users when using client certificate-based authentication and to bypass certain security restrictions. Other attacks are also possible. These issues are being tracked by Cisco Bugid CSCSZ04690 and CSCTA04885
