Adobe Acrobat Reader Plugin XMLHTTP ActiveX object HTTP response splitting

adobe-acrobat-xmlhttp-response-splitting (31291) The risk level is classified as MediumMedium Risk

Description:

The Adobe Acrobat Reader Plugin when used with the Microsoft.XMLHTTP ActiveX object is vulnerable to HTTP response splitting attacks, caused by improper validation of input passed to PDF documents. A remote attacker could exploit this vulnerability using the FDF, XML, or XFDF parameter in a specially-crafted URL to 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, cross-site scripting, and possibly obtain sensitive information.
