SYSTEMS AFFECTED
surfCONTROL SuperScout v2.6.1.6 flaw
PROBLEM
Mike Civ found following (tested on NT Server 4.0 SP5).
Vulnerability:
-Blocking Internet access based on surfCONTROL's categorization of a particular site.
-Example: Rule - No Access to Adult sites Anytime
-"www.playboy.com" successfully blocked.
-"www.playboy.com." let right through the filter.
-"www.penthouse.com" successfully blocked.
-"www.penthouse.com." let right through the filter.
One of the product's features is it's ability to block a user
from viewing a particular web site based on a classification
database. Inside this database, web sites like www.playboy.com
are categorized. Among the categories are Adult, Gambling,
Sports, etc. Rules can be implemented based on user, time,
category (Example: Disallow Everyone to Adult sites at anytime
throughout the day).
With IE5, behind surfCONTROL's rules, attempt to visit a
restricted site (this will vary on the admin's rules.) Add a "."
(period) after the blocked URL. Access is granted. The web
site/activity is logged by surfCONTROL, however the "." bypasses
the categorization. Within the logs, such a site will show with
a category of "None".
SOLUTION
No patch is available to date, but in plans.
