The sample is a PDF document that contains an embedded XFA form. Heuristics indicate it exploits CVE-2010-0188, a vulnerability in Adobe Reader related to LibTIFF processing within XFA forms. This exploit is designed to execute arbitrary code on the victim's machine. The embedded URL is likely related to the XFA template but does not appear to be a direct payload delivery URL.
