'Name' => 'HP OpenView Network Node Manager ovalarm.exe CGI Buffer Overflow',
|
|
'Description' => %q{
|
|
This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53.
|
|
By sending a specially crafted CGI request to ovalarm.exe, an attacker can execute
|
|
arbitrary code.
|
|
|
|
This specific vulnerability is due to a call to "sprintf_new" in the "isWide"
|
|
function within "ovalarm.exe". A stack buffer overflow occurs when processing an
|
|
HTTP request that contains the following.
|
|
|
|
1. An "Accept-Language" header longer than 100 bytes
|
|
2. An "OVABverbose" URI variable set to "on", "true" or "1"
|
|
|
|
The vulnerability is related to "_WebSession::GetWebLocale()" ..
|
|
|
|
NOTE: This exploit has been tested successfully with a reverse_ord_tcp payload.
