This exploits a buffer overflow in the request processor of
|
||
|
|
the Internet Printing Protocol ISAPI module in IIS. This
|
||
|
|
module works against Windows 2000 service pack 0 and 1. If
|
||
|
|
the service stops responding after a successful compromise,
|
||
|
|
run the exploit a couple more times to completely kill the
|
||
|
|
hung process.
