Google has fixed a security flaw on its web portal that opened the door to account identity theft, phishing scams and other threats.
The cross-site scripting vulnerability existed on the website for Google's AdWords advertising programme and a customer training site, said internet security company Finjan Software, which discovered the flaw.

Finjan said remote attackers could have exploited the flaw to hijack Google accounts, launch phishing scams or download malicious code onto users’ computers.
Google confirmed the flaw and said it corrected the problem before any user data was lost or compromised.
Finjan said the security problem related to forms on Google's website not validating and filtering data entered into certain fields. This left the way open for attackers to inject extra content and scripts that could be run on users’ computers.
Attackers would have then been able to craft special web links on the site, which would have to be clicked by users for their machines to become compromised.
