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 29.0 on Android allows remote attackers to spoof the address bar via crafted JavaScript code that uses DOM events to prevent the reemergence of the actual address bar after scrolling has taken it off of the screen.

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

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Mozilla Firefox for Android is installed
    Check the installed applications on the Android device for 'Firefox' or 'Mozilla Firefox' browser application
    Affected if The browser is Mozilla Firefox on Android
  2. Determine the Firefox version number
    Open Firefox, tap the menu (three dots), go to Settings, then About Firefox to view the version number
    Affected if Version displayed is 28.0 or lower, or matches any of these early versions: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.6.1, 0.7, 0.7.1, 0.8, 0.9
  3. Verify browsing is possible on the device
    Confirm the Firefox browser can load web pages (this vulnerability is triggered when browsing to any webpage containing crafted JavaScript)
    Affected if The browser can load web pages, as the vulnerability is triggered through JavaScript code in webpages

A user is affected if they have Mozilla Firefox for Android version 28.0 or lower installed and use the browser to visit webpages, as the address bar spoofing occurs when specific JavaScript code prevents the address bar from updating after scrolling.
