Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 43.0

Description The issue is related to improper access restriction to the IFRAME Resource Timing API in the browser. This can be exploited by a remote attacker to bypass the existing access policy or obtain confidential information using specially crafted JavaScript code. The exploitation involves using history.back and performance.getEntries calls.

Recommendations For versions prior to 43.0, update to version 43.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the IFRAME Resource Timing API until a patch is available. Avoid using the performance.getEntries function in conjunction with history.back calls in affected API endpoints until the issue is resolved.
