CVE-2020-6828: Path Traversal

First published: Tue Apr 07 2020(Updated: )

A malicious Android application could craft an Intent that would have been processed by Firefox for Android and potentially result in a file overwrite in the user's profile directory. One exploitation vector for this would be to supply a user.js file providing arbitrary malicious preference values. Control of arbitrary preferences can lead to sufficient compromise such that it is generally equivalent to arbitrary code execution. Note: This issue only affects Firefox for Android. Other operating systems are unaffected.
