Vulnerability Name:

CCN-71509

Published:2011-11-29
Updated:2011-11-29
Summary:Privoxy is vulnerable to HTTP response splitting attack, caused by improper validation of input. A remote attacker could exploit this vulnerability uisng specially-crafted URL containing RFC 3986 characters to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
