cPanel, Netgear and Linksys susceptible to nasty attack ? The Register
Basically, if you are logged into cPanel in one tab and surf to an infected site, that site will see your cPanel and take it over. Obviously you would be screwed. cPanels patch is in QA testing and not yet released. For the time being, always log out of cPanel before you visit any website. In fact there is no reason to leave cPanel logged in at all if you are not using it. Expect the best, plan for the worst.
