Yesterday morning I read the article on The Tech Herald about the demonstration of a CSRF flaw for ‘Change Password’ in Google Mail. While the vulnerability report has been known for some time, this is the first public proof of concept I am aware of.

“An attacker can create a page that includes requests to the “Change Password” functionality of GMail and modify the passwords of the users who, being authenticated, visit the page of the attacker,” the ISecAuditors advisory adds.

The Google response?

“We’ve been aware of this report for some time, and we do not consider this case to be a significant vulnerability, since a successful exploit would require correctly guessing a user’s password within the period that the user is visiting a potential attacker’s site. We haven’t received any reports of this being exploited. Despite the very low chance of guessing a password in this way, we will explore ways to further mitigate the issue. We always encourage users to choose strong passwords, and we have an indicator to help them do this.”

Uh, maybe, maybe not. Last I checked, people still visit malicious sites either willingly or by being fooled into it. Now take just a handful of the most common passwords and try them against 300 million accounts and see what happens.

How does that game go? Rock beats scissors, scissors beat paper, and weaponized exploit beats corporate rhetoric? I think that’s it.
