Description
A remote overflow exists in Microsoft Windows NT, 2000 & XP. The Microsoft Windows MSRPC Plug and Play service fails to validate user supplied data to the wsprintfW call within the code for UMPNPMGR, resulting in a stack buffer overflow. With a specially crafted request, a remote authenticated attacker can execute arbitrary code with SYSTEM privileges on a remote Windows 2000 or XP SP1 system. On Windows XP SP2, this vulnerability could also be exploited by an unprivileged user to gain full privileges on a system to which he is logged in interactively. Both resulting in a loss of integrity to the system.
