Due to the continued development of Internet technology, more and more people are willing to take advantage of high-interaction and diverse web applications to deal with commercial, knowledge-sharing, and social activities. However, while web applications deeply affect our society by degrees, hackers start exploiting web application vulnerabilities to attack innocent end user and back-end database, and therefore pose significant threat in information security.
According to this situation, this paper proposes a detection mechanism based on Model Checking to detect web application vulnerabilities. We reduce the problem whether the vulnerabilities exist or not to a kind of SMT (Satisfiability Modulo Theories) problem, and analyze all of the traces of tainted data flow in web applications to find possible vulnerabilities by SMT solver. The experimental results show that the method we proposed can identify SQL injection and XSS vulnerabilities effectively, and prove our method is a feasible way to find web application vulnerabilities.
