XHUNTER: Tracking XSS on the Net


"Code-injection attacks through Cross-Site Scripting (XSS) in the web browser
have observed a significant increase over the previous years. According to a
September-2009 report published by the SANS Institute, attacks against web
applications constitute more than 60% of the total attack attempts observed on
the Internet. Web application vulnerabilities such as SQL injection and
Cross-Site Scripting flaws in open-source as well as custom-built applications
account for more than 80% of the vulnerabilities being discovered. In this
project we propose the design and development of a prototype that can inspect
passively the network for extracting URLs that can potentially exploit a web
application, through XSS. The detector assumes that all URLs that contain
parts that can produce a valid JavaScript syntax tree are considered
suspicious. We will develop tools that identify text fragments of URLs,
exchanged in the network, that produce a valid JavaScript syntax-tree of high
depth. These URLs are considered as possible XSS exploitation attempts."
