Mozilla WebIDL chrome-privileged JavaScript execution via window.open

IdentifiersCVE-2014-1510CWE-94

CVE-2014-1510 is a privilege-escalation vulnerability in the Web IDL implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25. According to the provided description, a remote attacker can use an IDL fragment to trigger a window.open call and cause arbitrary JavaScript to execute with chrome privileges. In Mozilla terminology, chrome privileges correspond to highly privileged browser-internal execution context, making this effectively a sandbox/privilege boundary bypass from web content into privileged browser code.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows remote code or script execution in a chrome-privileged context within the affected Mozilla application. This can result in full compromise of the browser security boundary, access to privileged browser functionality and sensitive data, and, per the Mozilla advisory provided, arbitrary code execution with the full privileges of the browser, potentially leading to complete compromise of the affected system.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure to untrusted web content and avoid visiting suspicious or attacker-controlled websites. In environments using Thunderbird and SeaMonkey, risk is somewhat reduced because scripting is disabled by default, as noted in the provided advisory.

Remediation

Patch, then assume compromise.

Upgrade affected products to fixed versions: Firefox 28, Firefox ESR 24.4, Thunderbird 24.4, or SeaMonkey 2.25 or later. These releases contain the vendor fix for the vulnerable Web IDL behavior.
