RE: Comparison report on web app security scanners

["Erwin Geirnaert" <egeirnaert () securityinnovation be>]

There is a compilation of open-source applications called Securibench
from Stanford University:
http://suif.stanford.edu/~livshits/securibench/
These are all Java based and include WebGoat. So if someone can test
these applications that would be great! Or the security tool vendors can
use their tools to find vulnerabilities in open-source apps and share
that 

For me the discussion is not about the use of WebGoat or how the tests
were executed. I've read Dr. Peine his report in German and it was a
greatdocument. Everything was described in detail and how the tests were
executed. If you compare his results with the results of Arian Evans,
there is a lot of similarity.

Remark: if a security assessment tool is unable to keep state to test an
application it cannot be used. If you look at AJAX, or Struts taglib,
you need state in every request...

Ofcourse there are some other interesting articles from eWeek and
Infoworld that tested most security assessment tools out there. So
google for that if you want more information.

Anyway, I will present on Owasp 2006 about "Can (automated) tools test
for the OWASP Top 10" so if you have any experience that you want to
share, mail me. 

Regards,

Erwin

Hello,

I would like to add several important comments to this thread, in behalf
of Watchfire:

According to tests done in Watchfire's labs, when using AppScan 6.0 SP2
+ update 553 on the WebGoat application - AppScan will find 85 links,
will create 9557 tests and will eventually find 31 issues (211 different
test variants).
 
People who perform such benchmarks against WebGoat should pay attention
to the fact that AppScan needs some configuration in order to run
successfully on this application - 

- Explore method should be set to DFS (Depth First)
- Scan should be done in Single threaded mode
- Path limit should be disabled (no path limit)
- Depth limit should be enabled (otherwise one of the lessons gets into
an infinite loop)
- HTTP Authentication - use guest/guest
- Add the "Screen" parameter to the black-list (untested parameters)
- Auto-form filler should be enabled 

(!!!) IMPORTANT: all of the above configuration items existed in AppScan
for a long time, these were not added in order to "cook the product" to
work properly on WebGoat. 

In addition I support what Acunetix mentioned, WebGoat and the
FoundStone (Hackme) banking applications are poor examples to be testing
on.
 
I am also quoting Mark Curphey (OWASP), regarding OWASP's WebGoat
project:
"That said its (i.e. Foundstone's HackMe bank) not a good benchmarking
tool for testing these tools, nor is WebGoat"  - taken from:
http://seclists.org/lists/webappsec/2005/Oct-Dec/0025.html 
 
Thank you very much,
-Ory Segal

Hello,

A few days ago Dr. Holger Peine published a "Comparison report on web
app security scanners".

For this report he used two web applications: one of them is WebGoat and
the other one is a proprietary application which is not public.

I don't know anything about this proprietary application but I would
like to say that WebGoat is not a good test case for evaluating web
scanners.

WebGoat is using server side state variables to track user actions. For
example, if you want to test the String SQL injection flaw you first
need to navigate to the "String SQL injection" section in order to set
the proper state of the application.

If the application is not in the proper state, the SQL injection test
will not work. The application will just ignore your inputs.

An automated scanner cannot guess this application behavior, and unless
you optimize your scanner for this particular application it will not be
able to scan it properly.

When the scanner has finished discovering the site structure, WebGoat
will be in some unknown state. All tests will be performed while WebGoat
is in this state.

This is not a common implementation.

Because we are offering free audits, we have audited more than 1,000
websites and didn't encountered this kind of implementation.

WebGoat is great for learning about web security flaws but I don't think
it should be used as a test case for web security scanners.
