Descriptions

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."

La función MPC::HexToNum en el fichero Helpctr.exe de la Ayuda de Microsoft Windows y soporte técnico en Windows XP y Windows Server 2003 no controla correctamente las secuencias de escape con formato incorrecto, lo que permite a atacantes remotos eludir la lista blanca de documentos de confianza (La opción fromHCP) y ejecutar comandos de su elección a través de una URL hcp:// debidamente modificada.
