Official Description
NWFILTER.SYS in Novell Client 4.91 SP 1 through SP 4 for Windows 2000, XP, and Server 2003 makes the \.\nwfilter device available for arbitrary user-mode input via METHOD_NEITHER IOCTLs, which allows local users to gain privileges by passing a kernel address as an argument and overwriting kernel memory locations.
Technical Analysis
CVE-2007-5667 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
