- JSLR – thespanner.co.uk
Cross-Site Scripting (XSS) has been around for ages – with first incidents being reported in the late nineties. Despite the attack technique not being the most complex of all, XSS is not only still around in 2011 but has gained incidence and gravity. In many real life attacks XSS was used as an entry-door for other exploits, such as the successful source code compromise against the Apache Foundation and several attacks against code management systems and Intranet systems.

These strategies are similar to those used in other dumb fuzzers such as zzuf and fuzz. Because these mutators work at a binary level, they work best against binary file formats. Copy, an additional “strategy,” doesn’t actually fuzz the seed file, but can be useful for testing a new config or triaging known crashing test cases.
