Description

This module exploits a stack based buffer overflow in Ultra Mini HTTPD 1.21,
allowing remote attackers to execute arbitrary code via a long resource name in an HTTP
request. This exploit has to deal with the fact that the application's request handler
thread is terminated after 60 seconds by a "monitor" thread. To do this, it allocates
some RWX memory, copies the payload to it and creates another thread. When done, it
terminates the current thread so that it doesn't crash and hence doesn't bring down
the process with it.
