IMPACT:
Security Bypass
WHERE:
Local system
SOFTWARE:
Prevx Pro 2005 1.x
http://secunia.com/product/5317/
DESCRIPTION:
Tri Huynh has discovered two vulnerabilities in Prevx Pro 2005, which
can be exploit to bypass security features provided by the product.
1) Incorrect handling of memory mapped files allows protected files
that are mapped into memory using "MapViewOfFile()" to be written.
This can be exploited to bypass the product's file protection
security feature.
2) The driver does not validate the sender of received device I/O
control codes. This allows a user-space program to bypass the
product's security features by sending specific I/O control codes to
the driver.
The vulnerabilities have been confirmed in version 1.0. Other
versions may also be affected.
SOLUTION:
Do not run untrusted programs.
PROVIDED AND/OR DISCOVERED BY:
Tri Huynh
