Hi Richard and other webappsec-readers,
Thanks for your repies to my question on Java Web Application security.
I'm looking into application-level intrusion detection for Java Web
Applications and Web Services Therefore it would handy to have some
examples of real-world vulnerabilities discovered in Java WA/WS.
While it is very easy to find some publicly available examples of PHP
web applications with known vulnerabilities (e.g. bugtraq and an
archived PHPnuke version), it turns out to be rather hard for Java web
applications. This is probably due to a combination of factors: PHP is
more popular for non-business (e.g. open-source) web application
development, PHP requires less programming skills than Java, and PHP is
probably also more prone to some classes of vulnerabilities (e.g., no
support for SQL prepared statements).
So, I would be very interested in some real-world Java web applications
with known vulnerabilities. Does anyone have some pointers to such
applications or vulnerable code snippets? That would be a great help...
Thanks,
Chris.

Java based services; I've also kept a look out for such applications
being used as conduits to other services where buffer overflows be used.
Often web services act as a transport/portal to a non java based
application. While this is in the minority of web services I have seen,
I have ran in to it a couple of times.
For the large usage of web services, most clients look at leakage of
confidential information and/or unauthorized use of a sensitive
operation the web service offers.
Cheers,
Richard

Chris,
We examine many large web apps and web services. The easy way to answer
your
question is that Java apps have all the common problems *except* buffer
overflows and related problems. The most common, in my opinion, are
problems
related to input validation, access control, and authentication.

Hi all,
I'm working on practical security of Web Applications and Web
Services,
especially on applications written in Java.
You find a lot of information about the typical WA vulnerabilities
(SQL
inj, XSS, session handling errors, ...). Information that is more
difficult to find is on which vulnerabilities are more likely in
applications written in certain programming languages (or developed
using a particular framework, concepts or tools).
For my work it would be interesting to have an idea about which
vulnerabilities are often encountered in WA or WS written in Java
(using
JSP, Servlets and EJB's).
Is there anybody on this list who has seen some results of penetration
tests or audits of Java WA/WS? What are the most common
vulnerabilities
discovered?
Kind regards and thank you in advance,
Chris.
