This is a guest piece by Jamie Riden / @pedantic_hacker. Jamie has been doing penetration tests, secure development training and security code review since 2010 - and other kinds of computer-wrangling for much, much longer.
Having been a systems engineer, a coder and now a pen-tester, I’d like to take a brief moment of your time to talk about layered defenses; specifically in this case why running a web application firewall is a good idea. In my current job I get engaged to do various forms of pen-testing. Relatively often, we turn up something in a web application that could have been prevented in a couple of ways. Last week for example, I found a lovely old-school OS command injection bug in a single parameter of a reasonable-sized website.

This article explores how to use an uninitialized Bash variable to bypass WAF regular expression based filters and pattern matching. Let’s see how it can be done on CloudFlare WAF and ModSecurity OWASP CRS3.

Chris Romeo from the AppSec Podcast did an interview with our own Christian Folini during the AppSecEU conference in July. The 25min interview has been published lately.
The interview discusses the project itself, the upcoming 3.1 release, plans to expand beyond ModSecurity and CRS fits into agile development.
Here is the link to the interview: https://www.securityjourney.com/blog/crs-and-an-abstraction-layer-s04e02/

We are launching the monthly news anew. The idea is to look beyond the pure CRS development again and to bring you additional information that touch on our project. As the editor, I (-> Christian Folini) am planning to release this in the first half of the month. This did not work in July, though, but I have a very cute excuse: She’s called Giovanna and she is only a couple of days old. We’re going to be a bit earlier in August, but also less news apparently.

This is a brief coverage of the CRS Community Summit during AppSecEU in London last week.
Over 25 people followed our call for this first face to face meeting of the CRS developer team (6 of 10 developers with commit rights in the same room!) and the community. We have been very happy to have several end users, Trustwave representing the ModSecurity development, but also some of the big integrators in the room. There was AviNetworks, BitSensor, cPanel, Fastly, Kemp, Microsoft, NGINX, Verizon, etc. Finally also researchers and a representative from KISA, the Korean Internet Security Agency, and Ivan Ristić, original developer of ModSecurity for old times sake.

The very first meetup of the CRS community is only one week away now and it’s time to announce our program. As stated here on the blog before, this is meant as an opportunity to build ties, to get inspiration from the community and to understand what people are doing with CRS. So there are going to be talks, but there is a lot of room for talking and discussion.
So we are going to do a networking / poster session that lives on your contributions. You are invited to bring along a poster, put it up on the wall in our room and we will give you time to present it to our audience. We are interested in use cases, success stories or unique approaches to integrating CRS3. Also ideas and pitches for new projects within our community are welcome. Standard flipchart format. Please be aware you should bring it along in physical form: we can’t print it on site. But we will have tape available for you.

A Web Application Firewall (WAF) raises concerns that it does not fit into the DevOps methodology. The problem is that when a WAF is added to production, the impact on the application is tested too late. The application developer gets extremely late feedback and the WAF could break the application. This can lead to production issues.
But what if a WAF is involved in the DevOps process very early on and not just at the end, at production?

The organisation of the CRS community summit at the OWASP AppSecEU conference is coming along nicely.
Remember, we are going to meet in London on Wednesday, July 4 at 4pm, to talk about CRS, and about the way our users, our integrators and their users work with CRS. The program will include information about CRS 3.1, a recent proposal for a rule meta language above CRS (to give the rule set a wider audience) and the most important thing: Time to meet and talk to fellow users!

The OWASP ModSecurity Core Rule Set project will meet on Wednesday July 4, at 4pm in London to hold it’s first community summit. We scheduled this for the night before the AppSecEU conference in London on Thursday and Friday so people would have a real incentive to make the trip.

Truth be told, the three project leads, Chaim, Walter and me have never met in person and physical contact is similarly rare between the committers, let alone the commercial suppliers or the thousands of users worldwide.

This is the CRS newsletter covering the period from Early February until today.
We held our monthly community chat. We had quite a few people stop by.
csanders lifeforms franbuehler emphazer dune73 agi squared fzipi spartantri Our agenda from before the chat is available here. During the chat we discussed the following:
We added support for ModSecurity-v3/Apache and Modsecurity-v2/Nginx to the CRS Support ModSecurity Docker Repos. These will be used when testing before a release. Additionally, we will be adding testing with Nginx+FTW in addition to Apache+FTW.
