Windows DNS Server in Microsoft Windows 2000 SP4, Server 2003 SP1 and SP2, and Server 2008, when dynamic updates are enabled, does not restrict registration of the "wpad" hostname, which allows remote authenticated users to hijack the Web Proxy Auto-Discovery (WPAD) feature, and conduct man-in-the-middle attacks by spoofing a proxy server, via a Dynamic Update request for this hostname, aka "DNS Server Vulnerability in WPAD Registration Vulnerability," a related issue to CVE-2007-1692.
The FTP client in Windows XP SP1 and Server 2003, and Internet Explorer 6 SP1 on Windows 2000 SP4, when "Enable Folder View for FTP Sites" is enabled and the user manually initiates a file transfer, allows user-assisted, remote FTP servers to overwrite files in arbitrary locations via crafted filenames.
The RtlDosPathNameToNtPathNameU API function in NTDLL.DLL in Microsoft Windows 2000 SP4 and XP SP2 does not properly convert DOS style paths with trailing spaces into NT style paths, which allows context-dependent attackers to create files that cannot be accessed through the expected DOS path or prevent access to other similarly named files in the same directory, which prevents those files from being detected or disinfected by certain anti-virus and anti-spyware software.
