Veracode announced findings from the 2017 State of Software Security Report, a comprehensive review of application security testing data from scans conducted by a base of more than 1,400 customers.
Among other industry trends such as vulnerability fix rates and percent of applications with vulnerabilities, the report exposes the pervasive risk from vulnerable open source components. Researchers found that 88 percent of Java applications contain at least one vulnerable component, making them susceptible to widespread attacks. This is in part because fewer than 28 percent of companies conduct regular composition analysis to understand which components are built into their applications.
“The universal use of components in application development means that when a single vulnerability in a single component is disclosed, that vulnerability now has the potential to impact thousands of applications – making many of them breachable with a single exploit,” said Chris Wysopal, CTO, CA Veracode.
The past year
Over the past 12 months, several high-profile breaches in Java applications were caused by widespread vulnerabilities in open source or commercial components. One example of a widespread component vulnerability was the Struts-Shock flaw disclosed in March 2017. According to the analysis, 68 percent of Java applications using the Apache Struts 2 library were using a vulnerable version of the component in the weeks following the initial attacks.
This critical vulnerability in the Apache Struts 2 library enabled remote code execution (RCE) attacks using command injection, for which as many as 35 million sites were vulnerable. Using this pervasive vulnerability, cybercriminals were able to exploit a range of victims’ applications, most notably the Canada Revenue Agency and the University of Delaware.
Using vulnerable components
The research also shows that approximately 53.3 percent of Java applications rely on a vulnerable version of the Commons Collections components. Even today, there are just as many applications using the vulnerable version as there were in 2016. The use of components in application development is common practice as it allows developers to reuse functional code – speeding up the delivery of software. Studies show that up to 75 percent of a typical application’s code is made up of open source components.
Wysopal continued, “development teams aren’t going to stop using components – nor should they. But when an exploit becomes available, time is of the essence. Open source and third party components aren’t necessarily less secure than code you develop in-house, but keeping an up-to-date inventory of what versions of a component you are using. We’ve now seen quite a few breaches as a result of vulnerable components and unless companies start taking this threat more seriously, and using tools to monitor component usage, I predict the problem will intensify.”
The use of vulnerable components is amongst the troubling application security trends. For example, CA Veracode’s SoSS Report findings show that while many organisations prioritise fixing the most dangerous vulnerabilities, some still face challenges efficiently remediating software issues.
Even the most severe flaws require significant time to fix (only 22 percent of very high severity flaws were patched in 30 days or less) and most attackers are leveraging vulnerabilities within days of discovery. Hackers and nation state organisations are given ample time to potentially infiltrate an enterprise network.
In addition to information regarding the threat posed by the use of vulnerable components, Veracode also found:
- Vulnerabilities continue to crop up in previously untested software at alarming rates. 77 percent of apps have at least one vulnerability on initial scan.
- Government organisations continue to underperform those in other industries. Not only did they have a 24.7 percent pass rate at latest scan, they also had the highest prevalence of highly exploitable vulnerabilities like cross-site scripting (49 percent) and SQL injection (32 percent).
- Comparatively, between first and last scan, critical infrastructure had the strongest OWASP pass rate (29.8 percent) across all industries studied, though it saw a slight decline in pass rate (29.5 percent) on last scan. Two industries showing slight improvements between first and last scan include healthcare (27.6 percent vs. 30.2 percent) and retail & hospitality (26.2 percent vs. 28.5 percent).
