Taint Assisted DOM-XSS Fuzzing with Dominator Pro
fuzzing,DOM/type-0 XSS,data tainting
DOM XSS is an injection vulnerability for which few attack grammars do exist. The problem formalization can be derived from . There exist a fuzzer integrated in the penetration testing tool Dominator Pro . It is not clear how this fuzzing module does perform: it is likely that this module iteratively submits all values from a dictionary and keeps iterating until a given test verdict is obtained. In this mini research exercise, we want to address this fuzzing process in the following ways:
- how to generate an input sequence knowing previously submitted sequences?
- which input parameters to choose?
- which values to provide on those?
- how to assess if a given input sequence is promising towards triggering this bug?
- formalize the DOM XSS problem
- explain how the DOMinator Pro fuzzer does work
- list and content of existing DOM XSS attack grammars
- write a DOM-XSS attack grammar
- interface with Dominator Pro to programmatically obtain:
- the number of tainted nodes
- the list of performed transformations on sources
- if a DOM XSS attack did occur or not (test verdict)
- write a fitness function for directing DOM XSS fuzzing
- write an evolutionary fuzzer
- propose a methodology for producing a DOM-XSS grammar
- what are the intuitions for writing the most relevant fitness function dimensions?
- compare the built-in DOMinator Pro fuzzer with the one you wrote (criteria to be defined)

- create an archive on the ensimag server, so that only your team members and I have access to it.
