Description

Microsoft IIS contains a flaw that allows a remote attacker to execute arbitrary code on a vulnerable server. The issue is due to the .printer ISAPI (Internet Services Application Programming Interface) Internet Printing Protocol (IPP) filter, handled by \WINNT\System32\msw3prt.dll, containing a buffer overflow. When a buffer of 420 bytes is sent within the HTTP Host: header of a .printer ISAPI request, the buffer is overflowed allowing the attacker to overwrite the EIP register and execute arbitrary code with SYSTEM access.
