OWASP's VulnXML Database
Ingo Struck writes "The
Open Web Application Security Project released the VulnXML db for early access to the public. VulnXML is a description of static known vulnerabilities. It provides all necessary information to let an execution engine automatically craft and launch appropriate HTTP, SOAP or WebDAV requests and analyse the response whether the attack had success. Besides it provides some human readable classification of the
described vulnerability. A tool to execute VulnXML records is currently being developed and will help developers to check their web applications against a suite of well-known vulnerabilities described in a portable format."
As always, it sounds like this is a double egded sword -- won't this give script-kiddies a new engine for quickly scanning for possibly vulnerable targets?
Not that I'm saying this is a bad thing -- it's just one more tools that security professionals will have to use to stay ahead of the competition.
Just in time for July 6th!
Now that's security by obscurity! <rimshot />
Thank you, ladies and germs, I'll be here all week.
Carousel is a lie!
so we've just replaced script kiddies with a (very small) shell script?
Free as in mason.
This could also be used to create a "Super" Nessus. Remember that script kiddies and system administrators both use such tools. I think that in the long run, it will help the latter more.
You can't judge a book by the way it wears its hair.
I honestly don't see the purpose in this site or the tool being developed to use it. I use Nessus on a daily basis and it seems to work just fine for this task.
I mean what more could you ask for... a client/server based vuln. scanner that will give you reports in xml, csv, txt, html, doc... Since the site and database has been created, maybe you should just write a program that exports the exploit tests as Nessus nasl scripts so we can do the tests and Snort rules so we can detect testing.
From the site:
This database is intended to enable the maintenance of a peer group based set of XML descriptions for web application attacks.
Most people here are comparing this to vulnerability scanners like nessus, but acording to the description provided by the website this appears to be something entirely different. It doesn't check for known vulnerabilities versus services, but rather tries various attacks on web applications. I'm sure that something out there has been created along these same lines before, but I've never heard of it. This sounds like a good idea, and an easy way for inexperienced web application designers to insure that they're not vulnerable to a large database of known attacks.
Sounds pretty cool to me.
...since tomorrow is apparently Defacement Day.

For those interested in open standards for vulnerability assessment, you should check out the Open Vulnerability Assessment Language (OVAL - http://oval.mitre.org/). OVAL provides assessments that DO NOT PERFORM THE ACTUAL EXPLOIT but rather specify logical conditions on the values of system characteristics and configuration attributes to characterize which systems are susceptible to a given vulnerability.
The assessments use SQL syntax but there is an XML version coming soon.
The Open Security Project (OpenSec - http://www.opensec.org/) is also developing a similar standard. The Advisory and Notification Markup Language (ANML - http://www.opensec.org/anml/) is not only working on assessment but an entire advisory format in XML.
Immunity's SPIKE Proxy (http://www.immunitysec.com/spike.html) offers a python, GPL, VulnXML engine, and has for some time. VulnXML is superior to Nessus-style scripting in many ways for purely web-based assessments. Similar to how Nessus says "for all ports that have a web server on them, run these tests" VulnXML allows a fully interoperable and "self-descriptive" way to say "For all files on the web server, check for file.bak, but ignore custom 404 pages that return 200 OK, etc".
In fact XML is just a serialization format. Alas a format with lots of unnecessary overhead.
The decision for using XML maybe was based upon it's "popularity" - I don't remember...
Fortunately the serialization format can be switched within seconds to something less overheaded (since we use the OCL with a generic serialization mechanism). So it is very easy to provide the good ol' properties format instantaneously.
IMO For VulnXML's duty some relational format is clearly overdone. A "path-based" / "navigational" format has great advantages regarding to performance and flexibility (not only in this case).
So - think of XML only to be a serialization form; the description itself is "path-based" deliberately, since it is
