Dear Christian, obviously you have a cookie in your browser on computer A. Assumed, that kleinanzeigen.ebay.de does not match the IP addresses of different attemts to access the user page, this seems to be the only way to verify, that you are still you. So, you could take a look into your cookie and see, what is saved there. I would say, you won’t find your password in there, nor a hash of your password, but a session ID. How long the session ID is valid after the last server request using this ID, depends on the website. But yes: You can hijack a session of any other user, when you find a way to steal their cookie. You should avoid this. Firefox has an option to automatically delete all cookies when closing the browser. Love Torsten On Mon, Jun 23, 2014 at 08:21:44PM +0200, Christian K. wrote:
Hi, i have a question if this is an attack vector (website is german want ad branch from ebay kleinanzeigen.ebay.de prob. english site affected too): On Computer A the browser (FF) has an open tab with the site where, when visited, user A is always signed on (because the specific site is the user panel). On Computer B user A wants to log into his account, but forgot his password. He successfully changed his password using the "forgot password" button and was able to log in. Then user A moves from Computer B to Computer A (which was off at the time user A was at Computer B) and starts its browser where he realizes that he is still logged into his account on the site without any password confirmation. As this happend to me, the question is: is this an attack vector (I assume it is) and how can I as a user protect myself? Am not really into security engineering (just non-sec-related software engineering...), so forgive my dumbness! Thanks.
