A Large Scale Study of Web Service Vulnerabilities
Sushama Karumanchi, Anna Squicciarini · 2015
The pervasiveness of Web Services, compounded with seamless interoperability characteristics, introduces security concerns that are to be carefully considered with the envisioned internet architecture. In this paper, we propose a comprehensive study on Web Service vulnerabilities. We consider not only well known Web-based vulnerabilities such as SQL injection, session replay etc, but we also analyze Web-Service specific vulnerabilities and their potential of attacks due to poor service construction and lack of service maintenance. In our analysis, we classify each of the studied vulnerability according to a new taxonomy, discuss remedies and impact, and propose methods of detection based on real-time analysis. Our analysis is supported by the results of a large scale study involving over 2,000 real-world Web Services. Finally, we leverage our empirical finding by introducing a proxy-based solution that shields services and clients from any possible attacks.
