Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Mozilla Firefox before 46.0 on Android does not properly restrict JavaScript access to orientation and motion data, which allows remote attackers to obtain sensitive information about a device's physical environment, and possibly discover PIN values, via a crafted web site, a similar issue to CVE-2016-1780.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Mozilla Firefox before version 46.0 on Android improperly restricts JavaScript access to device orientation and motion sensors (DeviceOrientation API). This allows malicious websites to access sensitive sensor data that can be used to infer physical environment information and potentially discover PIN values entered on the device.

MitigationUpdate Mozilla Firefox for Android to version 46.0 or later, which properly restricts access to orientation and motion sensor data.
