Firefox Exploit can Hack Gmail

Mozilla has taken another security blow with the discovery that Google user accounts can be accessed through a dangerous Firefox exploit.

The vulnerability, which is still in the wild some 10 days after its discovery on gnucitizen.org, allows hackers to access Google accounts, including Gmail, with cross-site scripting attacks.

A client or server-side exploit can be inserted into .zip files via open document formats from Microsoft Office 2007 and OpenOffice, and uploaded to a server where the Firefox JAR protocol extracts the compressed data.
