An anonymous reader writes "A cross-site scripting vulnerability may mean bad news for Gmail users. The ethical hacking group GNUCitizen has developed a proof-of-concept program that deftly steals contact information and emails from the popular web-based mail service. At the moment there are no 'wild' exploits for this vulnerability. The article discusses how lax security makes holes like this a problem for corporate IT houses as well as Google. '"People do use private accounts to store work information," IBRS security analyst James Turner said. "I've worked at one organization where this was implicitly expected, because the mail server at the time was so unreliable. But that scenario is certainly less than optimal. "In an ideal world, an organization would be able to draw a line in the sand and say that corporate data does not pass this point. The current reality is that there are Gen-Y workers who are sharing information with each other on multiple alternative communication channels--Gmail and Facebook included."'" This, just a few days after a search-based exploit was discovered.
