Session Management Security Hole in Orkut

tomcataxis (1118933) writes "You login to Orkut and network with your friends everyday and then you finally log out. But do you really log out? What does logging out mean? Logging out means you have closed your account. Your account is accessible to none, not even to you unless you authenticate yourself with your username and password once again. Apparently logging out has a different meaning for Orkut. When you log out of Orkut, not only can you use your account without authenticating yourself but attackers and the bad guys can also use your account without even knowing your user name and password. Yes! That's true! They don't need your user name to hijack your account. Then what do they need? 3 Indian hackers Susam Pal, Vipul Agarwal and Gaurav Mogre have disclosed a security hole in Orkut that can be exploited to compromise an account if certain Orkut cookies are stolen and the account can be used even after the owner of the account has logged out.

The following are the steps to protect yourself.

1. A user logged into Orkut should not run any untrusted JavaScript,
      program, etc. or click on any suspicious link to prevent the cookie
      from being stolen.
2. On a shared system, the user must log out of Orkut by clicking the
      "Logout" link. This would delete the session cookies at the browser
      and another user can not read the cookie value from the browser.
      Alternatively, the cookie can be removed from the browser.
