|
|
'Description' => %q{
|
|
|
|
This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53
|
|
|
|
prior to NNM_01203. By specifying a long 'arg' parameter when executing the 'jovgraph.exe'
|
|
|
|
CGI program, an attacker can cause a stack-based buffer overflow and execute arbitrary code.
|
|
|
|
|
|
|
|
This vulnerability is triggerable via either a GET or POST request. It is interesting to
|
|
|
|
note that this vulnerability cannot be exploited by overwriting SEH, since attempting
|
|
|
|
to would trigger CVE-2010-1964.
|
|
|
|
|
|
|
|
The vulnerable code is within a sub-function called from "main" within "ovwebsnmpsrv.exe"
|
|
|
|
with a timestamp prior to April 7th, 2010. This function contains a 256 byte stack buffer
|
|
|
|
which is passed to the "getProxiedStorageAddress" function within ovutil.dll. When
|
|
|
|
processing the address results in an error, the buffer is overflowed in a call to sprintf_new.
|
|
|
|
There are no stack cookies present, so exploitation is easily achieved by overwriting the
|
|
|
|
saved return address.
|
|
|
|
|
|
|
|
There exists some unreliability when running this exploit. It is not completely clear why
|
|
|
|
at this time, but may be related to OVWDB or session management. Also, on some attempts
|
|
|
|
OV NNM may report invalid characters in the URL. It is not clear what is causing this
|
|
|
|
either.
