FreeBSD : Ruby Activemodel Gem -- Circumvention of attr_protected (beab40bf-c1ca-4d2b-ad46-2f14bac8a968)

This script is Copyright (C) 2013 Tenable Network Security, Inc.

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

Aaron Patterson reports :

The attr_protected method allows developers to specify a blacklist of
model attributes which users should not be allowed to assign to. By
using a specially crafted request, attackers could circumvent this
protection and alter values that were meant to be protected.

All users running an affected release should either upgrade or use one
of the work arounds immediately. Users should also consider switching
from attr_protected to the whitelist method attr_accessible which is
not vulnerable to this attack.
