'Name' => 'Race River Integard Home/Pro LoginAdmin Password Stack Buffer Overflow',

|
'Description' => %q{
|
|
This module exploits a stack buffer overflow in Race river's Integard Home/Pro
|
|
internet content filter HTTP Server. Versions prior to 2.0.0.9037 and 2.2.0.9037 are
|
|
vulnerable.
|
|
|
|
The administration web page on port 18881 is vulnerable to a remote buffer overflow
|
|
attack. By sending an long character string in the password field, both the structured
|
|
exception handler and the saved extended instruction pointer are over written, allowing
|
|
an attacker to gain control of the application and the underlying operating system
|
|
remotely.
|
|
|
|
The administration website service runs with SYSTEM privileges, and automatically
|
|
restarts when it crashes.
