ALERT: How a hacker launches a Web application attack step-by-step Learn
why 70% of today's successful hacks involve Web Application attacks such
as: SQL Injection, XSS, Cookie Manipulation, Session Hijacking and
Parameter Manipulation. All undetectable by Firewalls and IDS! Download

Occasionally, the SAC team comes across an advisory where we need to
determine whether or not the vulnerability discussed is indeed a bug,
configuration problem, user error, etc. A great example would be one
of the numerous PHP scripts, where playing around with a URL parameter
gets PHP to display error information. The vulnerability in this case
is not in the script--although it does house the bug, which lets this
vulnerability surface. Rather, the PHP configuration is set up to dump
diagnostic error information to the user. Fix your PHP configuration,
and you've fixed this entire class of problems. The same goes for IIS
ASP pages, which particularly love to dump ODBC error information,
thereby directly aiding in SQL tampering attacks. Plus, there are the
usual default passwords, users initiating denial of service attacks
against themselves, insecure storage of passwords used in insecure
protocols (IMAP, POP, FTP), etc.
Last week, Trust Factory released an advisory detailing how the
ShopFactory CGI shopping cart potentially allows a user to manipulate
items' prices. Granted, it's not great that the script allows this,
but it's also not the only way to take advantage of this type of
vulnerability. Traditionally, many shopping cart applications will
fire off an e-mail to a fulfillment contact for actual processing. With
enough knowledge, attackers can easily spoof that e-mail and indicate,
for example, that they should be sent 25 rubber duckies without
actually paying for them. This entire realm of problems is no different
than what retailers in the physical world have been dealing with for
years: fraud. You could walk into a store and put a $2.99 price tag on
a $59.99 item, and the only way you'll get caught is if the checkout
clerk is aware that the item in question is definitely not $2.99. In
addition, there's the entire foray into cloned and stolen credit cards.
In the end, online systems are just as susceptible to many of the same
methods of fraud as a physical world stores. We all know 100-percent
security is a myth. Otherwise, you would not be subscribed to this
newsletter. It is in a retailer's best interest to periodically
sample or check orders to ensure that the automated process has not
been tampered with. This checking procedure could even be automated,
as long as the check exists independently of other processes. For
instance, having the purchasing and verification programs use the
same price database doesn't help when someone manipulates a price to
an incorrect value within the database.
Back to ShopFactory... Does your company trust that a potentially
vulnerable CGI running on a potentially insecure Web server on a
potentially weak operating system sitting on a potentially untrustworthy
network interfacing with untrustworthy attackers is actually fulfilling
orders with no amount of fraud? Right, we didn't think so. If you double
check your orders independently of the purchasing process, you won't
have to worry about an outsider (or insider) buying your rubber duckies
for less than bargain basement prices.

*** {02.49.018} Win - Enceladus FTP server CD overflow
The Enceladus Server Suite version 3.9 reportedly contains a buffer
overflow in the handling of the 'CD' FTP command, thereby allowing
a remote attacker to execute arbitrary code on the system.
This vulnerability is not confirmed.

*** {02.49.021} Win - MS02-067: Outlook 2000 e-mail header DoS
Microsoft released MS02-067 ("Outlook 2000 e-mail header DoS"). The
Outlook 2000 (only) client crashes when it receives a particular type
of e-mail with a malformed header. The client will continue to crash
whenever it encounters the particular e-mail. Other Outlook versions
are not affected.

*** {02.49.023} Win - IPD kernel protection bypass
The Integrity Protection Driver prior to version 1.3 contains two bugs
that allow a local attacker to bypass the restrictions it is supposed
to provide: indirect access to \Device\PhysicalMemory via an object
symlink; and dependency on the system clock lets an attacker roll
the clock back in order to disengage the driver.
These vulnerabilities are confirmed and fixed in version 1.3.
