69 percent of web applications are plagued by vulnerabilities that could lead to sensitive data exposure, and 55 percent by cross-site request forgery flaws, the results of a security research project on web application vulnerabilities by Contrast Security revealed.
Broken authentication and session management issues affect 41 percent of web apps, while security misconfiguration and lack of function level access control is found on 37 and 33 percent of apps, respectively.
The research also found that 80 percent of tested software applications had at least one vulnerability, with an average of 45 vulnerabilities per application.
These results are based on the data collected from the Contrast Security platform across several popular development languages.
Top web application vulnerabilities by language: Java and .NET
Contrast Labs compared the top web application vulnerabilities across two of the most popular web application development languages: Java and .NET.
In so doing, they revealed that Java suffers from higher prevalence of cross-site request forgery (impacting 69 percent of Java applications, as compared to 31 percent in .NET) and less security misconfiguration problems than .NET (14 percent in Java versus 73 percent in .NET).
This is almost certainly because .NET relies far more on configuration than Java applications do; however, the high numbers of security misconfiguration in .NET indicate that this approach is not without its own set of problems.
Contrast Labs also found a lower number of injection flaws in .NET applications (affecting 17 percent of applications), where the use of persistence layers has helped to stamp out these flaws. However, injection flaws are still quite prevalent in Java applications at 38 percent, where there are many more database options. Injection, a common vulnerability often missed by traditional application security tools, can sometimes lead to a much more serious compromise. If attackers are able to pivot from injection to a complete host takeover, there’s no limit to the access that attackers would have to a software application’s data and capabilities.
“The level of application vulnerability revealed by this analysis is deeply concerning,” said Jeff Williams, CTO and co-founder of Contrast Security. “All of these vulnerabilities have been documented in the OWASP Top Ten for over a decade, yet they’re obviously still a major problem. Given the level of vulnerability and increasing threat, organizations should adopt a continuous application security strategy and make sure the development and security teams are bought in.”
