All BitTorrent Trackers built on the tb-source use this scheme, when you login you recieve a cookie with your password hash, when someone steals the cookie/pw-hash they can steal that account... Funny sidenote, tb-source is ofter vulnerable to XSS upb wrote:
this would effectively make the password hash the password. Are you sure this scheme is used?:P On 10/16/07, *Bipin Gautam* <gautam.bipin () gmail com <mailto:gautam.bipin () gmail com>> wrote: hi list, i was reading the article, http://www.f-secure.com/weblog/archives/00001293.html <http://www.f-secure.com/weblog/archives/00001293.html> but just an example. why do many people out there think password hash "can't be" as good as the password itself and needs to be computed/cracked first before it can be used? Consider the fact, many websites/forums don't use password hash+salt, just password hash( generally SHA1, MD5) that gets computer client side and POSTED to the web-forum for user authentication. If someone can sniff this, given that, user name is available using simple GUI tools as 'Tamper Data' ( firefox plug in ) even a low tech malicious user can log on with someones credentials without having to crack the password hash, instead just using the password hash itself manipulating the POST request. makes sense? :) thanks, -bipin _______________________________________________ Full-Disclosure - We believe in it.
