Hmm - I thought that sqwebmail was written to avoid this kind of vulnerability...

Visiting the link is been marked from our counter. Now we will be able to access to the victim's mail page admin and will be able to read and to send, calmly, its email without make login. The session comes sluice after approximately 20/30 minutes and the attacker has the time to make its comfortable ones. ************************* What could make a attacker? ************************* Read, write and fake your e-mail. Could send , from you email address, a mail to your ISP and ask it User e PASS of your website. The consequences would be catastrophic. ************************* What I can do ? ************************* Actually seems that there isn't a patch for this problem. ************************* Suggestion to SQWEBMAIL ************************* It would have to reduce the time for the closing of the sessions.
