Help Center URL Validation Vulnerability

oval:org.mitre.oval:def:11733

The MPC::HexToNum function in helpctr.exe in Microsoft Windows Help and Support Center in Windows XP and Windows Server 2003 does not properly handle malformed escape sequences which allows remote attackers to bypass the trusted documents whitelist (fromHCP option) and execute arbitrary commands via a crafted hcp:// URL aka "Help Center URL Validation Vulnerability."
