Description
This module exploits CVE-2021-31166, a UAF bug in http.sys
when parsing specially crafted Accept-Encoding headers
that was patched by Microsoft in May 2021, on vulnerable
IIS servers. Successful exploitation will result in
the target computer BSOD'ing before subsequently rebooting.
Note that the target IIS server may or may not come back up,
this depends on the target's settings as to whether IIS
is configured to start on reboot.
