Sanctum Paper on HTTP response splitting, web cache poisoning attacks, and related topics
Sanctum published paper on
"Divide and Conquer - HTTP response splitting, web cache poisoning attacks, and related topics" in March 2004. I read it last nights. It's an excellent read, very technical, with some sample code. It discusses the behaviour of common platforms, incl. IE 6.0 SP1, Squid 2.4, Apache/2.0, Netcache/5.2 and WebLogic 8.1 SP1. - It reads almost like a scientific paper, with a lot of helpful practical information. I think it really helps to understand some of the often-over-looked risks in web services security.
- After reading the paper, cache poisoning is no longer a remote possibility. (I know we've seen report on it being used for years, but this paper adds a new twist.)
