Hacking the Frontend Logic: Exploiting JavaScript Business Flaws
1 min read
Summary
Business logic flaws in the frontend JavaScript of web applications can be exploited by hackers, despite not being technical vulnerabilities.
These flaws arise from mistakes in the design of apps relating to processes such as user roles, billing, and shopping baskets.
The rise of popular frontend frameworks which perform complex processing in the client side has led to increased opportunities for hackers to exploit these flaws.
For example, hackers can tamper with pricing, giving them the chance to underpay for goods or services.
Developers need to be increasingly vigilant about these kinds of potential exploits as the front end becomes more important in application design.
