Forest Hill, MD, Sept. 09, 2017 (GLOBE NEWSWIRE) -- The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 350 Open Source projects and initiatives, today issued the following statement regarding the Equifax security breach:
Apache Struts Statement on Equifax Security Breach
The Apache Struts Project Management Committee (PMC) would like to comment on the Equifax security breach, its relation to the Apache Struts Web Framework and associated media coverage.
We are sorry to hear news that Equifax suffered from a security breach and information disclosure incident that was potentially carried out by exploiting a vulnerability in the Apache Struts Web Framework. At this point in time it is not clear which Struts vulnerability would have been utilized, if any. In an online article published on Quartz.com , the assumption was made that the breach could be related to CVE-2017-9805, which was publicly announced on 2017-09-04  along with new Struts Framework software releases to patch this and other vulnerabilities . However, the security breach was already detected in July , which means that the attackers either used an earlier announced vulnerability on an unpatched Equifax server or exploited a vulnerability not known at this point in time --a so-called Zero-Day-Exploit. If the breach was caused by exploiting CVE-2017-9805, it would have been a Zero-Day-Exploit by that time. The article also states that the CVE-2017-9805 vulnerability exists for nine years now.
We as the Apache Struts PMC want to make clear that the development team puts enormous efforts in securing and hardening the software we produce, and fixing problems whenever they come to our attention. In alignment with the Apache security policies, once we get notified of a possible security issue, we privately work with the reporting entity to reproduce and fix the problem and roll out a new release hardened against the found vulnerability. We then publicly announce the problem description and how to fix it. Even if exploit code is known to us, we try to hold back this information for several weeks to give Struts Framework users as much time as possible to patch their software products before exploits will pop up in the wild. However, since vulnerability detection and exploitation has become a professional business, it is and always will be likely that attacks will occur even before we fully disclose the attack vectors, by reverse engineering the code that fixes the vulnerability in question or by scanning for yet unknown vulnerabilities.
Regarding the assertion that especially CVE-2017-9805 is a nine year old security flaw, one has to understand that there is a huge difference between detecting a flaw after nine years and knowing about a flaw for several years. If the latter was the case, the team would have had a hard time to provide a good answer why they did not fix this earlier. But this was actually not the case here --we were notified just recently on how a certain piece of code can be misused, and we fixed this ASAP. What we saw here is common software engineering business --people write code for achieving a desired function, but may not be aware of undesired side-effects. Once this awareness is reached, we as well as hopefully all other library and framework maintainers put high efforts into removing the side-effects as soon as possible. It's probably fair to say that we met this goal pretty well in case of CVE-2017-9805.
Our general advice to businesses and individuals utilizing Apache Struts as well as any other open or closed source supporting library in their software products and services is as follows:
1. Understand which supporting frameworks and libraries are used in your software products and in which versions. Keep track of security announcements affecting this products and versions.
2. Establish a process to quickly roll out a security fix release of your software product once supporting frameworks or libraries needs to be updated for security reasons. Best is to think in terms of hours or a few days, not weeks or months. Most breaches we become aware of are caused by failure to update software components that are known to be vulnerable for months or even years.
3. Any complex software contains flaws. Don't build your security policy on the assumption that supporting software products are flawless, especially in terms of security vulnerabilities.
4. Establish security layers. It is good software engineering practice to have individually secured layers behind a public-facing presentation layer such as the Apache Struts framework. A breach into the presentation layer should never empower access to significant or even all back-end information resources.
5. Establish monitoring for unusual access patterns to your public Web resources. Nowadays there are a lot of open source and commercial products available to detect such patterns and give alerts. We recommend such monitoring as good operations practice for business critical Web-based services.
Once followed, these recommendations help to prevent breaches such as unfortunately experienced by Equifax.
