All sites said to be vulnerable
An independent security researcher, Rosario Valotta, suggests Internet Explorer is vulnerable to attacks that target the private data stored in HTTP cookies. The flaw is said to leave users open to what Valotta calls "cookiejacking," a method that hackers can reportedly use to access a cookie and log into victims' various online accounts.
The vulnerability is said to require users to drag and drop an item across the screen. Volatta claims to have created a Facebook app that exploits the flaw by requiring users to virtually undress a woman, enabling him to amass 80 cookies from his total list of just 150 friends.
Microsoft suggests the requirement for user interaction is unlikely to be used in an actual hacking scenario, company spokesman Jerry Bryant told Reuters.
The vulnerability is said to potentially affect all versions of Internet Explorer running on any Windows edition.
