CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
Local system

SOFTWARE:
First4Internet XCP Content Management
http://secunia.com/product/6033/

DESCRIPTION:
A security issue has been reported in First4Internet XCP DRM software
used to playback Sony copy-protected music CDs, which can be exploited
by malicious, local users to hide certain actions on a vulnerable
system from the Administrator.

The security issue is caused due to the "aries.sys" device driver
hiding all files, registry keys and processes on the system that have
names that start with "$sys$", regardless of whether the file is part
of the XCP software. This can be exploited by malicious users and
malware to hide files and processes from the Administrator by
prefixing their names with "$sys$".

SOLUTION:
Use another product.
