Discovering Business Logic Vulnerabilities in API Applications

27% of the cyberattacks involving APIs in 2023 were business logic attacks, reveals Imperva in “The State of API Security in 2024.” Also, the OWASP Top 10 API Security Risks and Hacker One Top Ten Vulnerabilities both include business logic vulnerabilities.???

A recent example highlighting the critical importance of early detection is Log4Shell, a business logic vulnerability that exposed organizations worldwide to severe security risks. Log4Shell leveraged unintended logic within the Log4j logging library’s API to execute malicious code, resulting in compromised systems, data theft, and large-scale disruptions. This incident underscores how overlooked or misconfigured application logic can be weaponized. Clearly, logic flaws pose a severe, frequent, and growing security threat. How do you deal with it effectively???

Discovering business logic vulnerabilities before malicious actors find them is the best place to start. This article shows you how to do that.?? ?

How You Can and Cannot Discover Business Logic Vulnerabilities?

Five factors are making manual business vulnerability discovery led by human experts utterly unrealistic:?

• The global shortage of cybersecurity professionals??
• The constantly evolving threat landscape??
• The worrisome API sprawl?
• The expanding API attack surface?
• The elusive nature of logic flaws??

What can you do instead???

• Use a purpose-built API security solution that relies on artificial intelligence and machine learning. These two innovative technologies are remarkably efficient in dealing with myriad scenarios, countless API sequences, and petabytes of data, which are all critical for discovering business logic vulnerabilities.??

• Make sure that this solution covers the OWASP Top 10 API Security Risks, as they include logic flaws and make up the basis for contemporary API vulnerability management.??

• At the same time, ensure that its vulnerability discovery goes beyond the OWASP API Security Top 10 since these ten vulnerabilities are far from constituting a comprehensive framework, especially considering all the possible scenarios of logic flaw exploitation.?

Equixly: Not Your Average AI-Powered API Security Tool?

Equixly ticks all the boxes above.?

It’s an automated API security solution built with business logic vulnerability management in mind. It was developed by API security specialists who saw the pitfalls of misplaced API application logic themselves. Hence, they made sure that the discovery of logic flaws is a trademark of this API security platform.?

Unlike traditional DAST-based solutions, Equixly understands API context and logic. It generates and tests a myriad of API sequences, looking for as many combinations as necessary to discover flaws in the implemented application logic.?

Further, through its proprietary AI engine and ML algorithms, Equixly dramatically shortens the time needed to perform business logic vulnerability discovery.?

As a final point, Equixly’s subscription is a fraction of the costs of manual API security testing and vulnerability discovery.?
