CVE-2012-4205

high

Description

Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 assign the system principal, rather than the sandbox principal, to XMLHttpRequest objects created in sandboxes, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks or obtain sensitive information by leveraging a sandboxed add-on.
