Vigil@nce - Cisco Web Security Appliance: Cross Site Scripting of HTTP
August 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can trigger a Cross Site Scripting in the HTTP
response headers from Cisco Web Security Appliance, in order to
execute JavaScript code in the context of the web site.
Impacted products: AsyncOS, Cisco WSA.
Severity: 2/4.
Creation date: 22/06/2015.
DESCRIPTION OF THE VULNERABILITY
The Cisco Web Security Appliance product offers a web interface.
However, it does not filter received data before inserting them in
generated HTTP response headers. So one can inject additional HTTP
response headers, and possibly a response body, that may include
scripts.
An attacker can therefore trigger a Cross Site Scripting in the
HTTP response headers from Cisco Web Security Appliance, in order
to execute JavaScript code in the context of the web site.
