'Name' => "HP System Management Homepage JustGetSNMPQueue Command Injection",
'Description' => %q{
This module exploits a vulnerability found in HP System Management Homepage. By
supplying a specially crafted HTTP request, it is possible to control the
'tempfilename' variable in function JustGetSNMPQueue (found in ginkgosnmp.inc),
which will be used in a exec() function. This results in arbitrary code execution
under the context of SYSTEM. Please note: In order for the exploit to work, the
victim must enable the 'tftp' command, which is the case by default for systems
such as Windows XP, 2003, etc.
