-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi kuza55,
Are you trying the payload that includes the tilde or the one without? The one with the tilde (~) only works if the payload returns after an opening angle bracket (<). Please see: http://www.procheckup.com/Vulnerability_PR08-20.php And yes, it also works on IE7. Just tried it on a live environment last week. kuza55 wrote: > Sorry for digging this up, but I can't replicate your findings on the > IE7 version you claim is vulnerable on your advisory. > > Your paper seems to say you only tested this on IE 5.5 and IE6 (no > mention of IE7), so does is that the case, or am I just doing it > wrong? > > 2008/8/22 ProCheckUp Research <[EMAIL PROTECTED]>: > The Microsoft .NET framework comes with a request validation feature, > configurable by the ValidateRequest setting.
