Gmail Security Hole: Do Not Use Web Interface
From the Windows Secrets Newsletter:
Gmail was warned for the past year about a security hole. They chose to do nothing about it and will apparently keep doing nothing about it.
The hole is similar to cross-site scripting (XSS) but not the same.
Do not access your gmail account with a browser. Even using the secure method (https) won’t help you. Using secure IMAP or POP is the only safe way for the time being.
Make sure you select secure IMAP or POP. Gmail has instructions on how to do this if you don’t already have it set up.

Thanks for the heads up! Will there be a posting when this is corrected?

I’ll be sure to post an update if I hear anything. Google doesn’t seem to be in any hurry to look into it. It’s been a year already.

Self: I’m pretty sure it’s any platform – thanks for asking. The hack is on the remote side.
Even if it isn’t, extra security never hurts. I prefer Thunderbird on linux, using secure IMAP or POP, but one can set this up on Win or Mac also. (not sure if Thunderbird is available for Mac)

Ok, I see the link to the newsletter which apparently did not show up in chrome for some reason.
It looks like the cure for this is a non standard password. Oh and stay away from sites that could potentially be trying this and stay on known good sites.

When you resort to IMAP or POP3, it screws up your ‘labels’ doesn’t it? Or did I miss fine print somewhere? I did try downloading to a local client, and it basically dumped everything in the Inbox.

Windows Sercrets doesnt know wtf they are talking about. The author says that CSRF exploits can intercept communication between your browser and the server. It would be nice if the author knew anything about his topic before writing about it.
Furthermore, how can anyone write about potential vulnerabilities without explaining what the vuln is, as you have done on this blog.

Gadget: sorry, I don’t use labels. They have pretty good implementation and documentation though. I’m pretty sure IMAP behaves.
Bryan: Sorry if you feel the alert and link aren’t sufficient. Feel free to send Windows Secrets a rude comment too.
Informative blog, btw. insecureweb.com]

I just came across this and have two questions… pardon my ignorance on the first one…
You say, “Make sure you select secure IMAP or POP.” I don’t see an option for that within the Gmail settings or within my email clients (I use both Thunderbird and Postbox). So any tips on how to go about this or find this would be greatly appreciated.
Also, I use Google Calendar on a regular basis. Am I at the same risk while using the calendar? I am kinda assuming that I am, being signed into the account and all.
Thanks to anyone who can shed some light on either of those two issues.
Cheers,
Pendimar
