Registration for the OWASP CRS Community Summit 2023 - Dublin, Feb 14

On February 14, the CRS community will meet at the Dublin Convention Center for the 2023 CRS Community Summit, the first summit after the pandemic.

REGISTRATION

It has been a while since last we met and many things have happened since. So, there is a lot to talk about.

We start at 9 am local time in Liffey Hall 1 of the Convention Center.

The program is still in the making, but please expect a variety of talks about CRS, ModSecurity and Coraza. Here is what we know:

Meet the CRS team: Fränzi, the puzzle-loving hard worker with a mission

Franziska Bühler doesn’t feel too comfortable in the limelight. The CISO of a Swiss mid-sized IT company rather likes to work through lists of hundreds of bypasses than being at the forefront. Talking to her, it gets clear quickly: Fränzi loves a challenge. “Once I set my mind to something, I follow through,” she says.

Microsoft Supports CRS as Gold sponsor

The OWASP ModSecurity Core Rule Set project is very happy to announce Microsoft as new GOLD sponsor. There have been sporadic contacts with the Azure WAF engineering team for several years and we are now taking the next step. Microsoft and OWASP CRS are establishing a formalized partnership in the form of a sponsoring agreement.

There is never a lack of ideas in a florishing open source project like ours. But as a lot of open source projects, we lack the user perspective to a wide extent. We write rules, but we do not really know how they behave in the real world outside of the few sites we control at our day jobs.

Save the Date: CRS Community Summit on February 14, 2023

Let the CRS project be your Valentine: The OWASP ModSecurity Core Rule Set
project will hold the first post-pandemic Community Summit at the Dublin
Convention Center in Ireland on Tuesday, February 14, 2023.

We invite the whole CRS community, users, developers, integrators, and sponsors
to meet with us for an exchange of thoughts, technical talks, and networking.
After the “official” part of the meeting we will go out for dinner and drinks.

Bug Bounty Switzerland supports CRS as Silver sponsor

The OWASP ModSecurity Core Rule Set (CRS) project is proud to announce a new sponsoring partner: Bug Bounty Switzerland – a startup that has pioneered the collaboration with ethical hackers in Switzerland and today is Switzerland’s leading provider of bug bounty programs and public trust initiatives. Since 2022, they are the strategic partner of the National Cyber Security Centre NCSC and help to establish bug bounty programs for the whole Federal Administration. Their customer base includes Swiss and international clients from various fields, as well as regulated industries like banking, insurance, healthcare and providers of critical infrastructures.

The CRS Developer Retreat 2022

Pizza, pasta, pesto … pineapple? This was one of the many important topics (and one of the most controversial) discussed at the CRS developer retreat 2022 in Italy. The annual CRS developer team retreat is always a highlight of the year, finally meeting face-to-face again and not just via chat.

This time, the backdrop for the meeting from October 29 to November 5 was the southern foothills of the Alps near Lake Varese, close to the Swiss border. Here, in Villa Cagnola, there was not only good food and drink – there was also a lot of work. The focus was on two items: preparing the rule set for the CRS v4 release and defining a strategy for the future of the project.

Meet the CRS team: Ervin, the gardening radio amateur in the background

Astronaut? Garbage truck driver? Electrical engineer? Metalsmith? In the end, Hungarian Ervin Hegedüs became a software developer. Within the Core Rule Set project, he contributes primarily to tool development and packaging. “New team members should above all be team players,” says Ervin.

Ervin Hegedüs has had no shortage of interesting career ideas in his 51-year life. While the usual childhood dreams of becoming an astronaut or a garbage truck driver vanished as he grew older, Ervin still today sometimes wonders what would have become of him if he hadn’t found his way to IT. He thinks he might have become an electrical engineer since he is a HAM radio operator in his spare time (callsign: HA2OS). More about that later.

Meet the CRS team: Andrea, the musical man-in-the-middle

He likes to play board games and the guitar, and he loves to fix bypasses to CRS rules: Italian Andrea Menin joined the Core Rule Set team in 2018. The most important requirement for anybody joining the project, he says, is to enjoy it.

CRS Version 3.3.4 and 3.2.3 fix a regression

Yesterday, we released CRS versions 3.3.3 and 3.2.2 with important security improvements.

Unfortunately, backporting the fixes from our development branch 4.0 introduced a regression which was only found after publication. As a result, some Paranoia Level 2 rules would activate even when running in Paranoia Level 1. This did not harm security but may introduce false alarms for those running in Paranoia Level 1. We have fixed this in two new releases:

CRS Version 3.3.3 and 3.2.2 (covering several CVEs)

Release announcement covering fixes for CVE-2022-39955, CVE-2022-39956, CVE-2022-39957 and CVE-2022-39958, additional security fixes and security fixes in the latest ModSecurity releases 2.9.6 and 3.0.8.

The OWASP ModSecurity Core Rule Set (CRS) team is pleased to announce the release of two new CRS versions.
Edit: Updated download links now to refer to the fixed versions.

Version 3.3.4 — https://github.com/coreruleset/coreruleset/releases/tag/v3.3.4
Version 3.2.3 — https://github.com/coreruleset/coreruleset/releases/tag/v3.2.3

This is a security release fixing several partial rule set bypasses with HIGH or even CRITICAL severity described in the following CVEs:
