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 27.0 and SeaMonkey before 2.24 allow remote attackers to bypass the Same Origin Policy and obtain sensitive information by using an IFRAME element in conjunction with certain timing measurements involving the document.caretPositionFromPoint and document.elementFromPoint functions.

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 · moderate confidence

This is a Same Origin Policy (SOP) bypass vulnerability in Mozilla Firefox before 27.0 and SeaMonkey before 2.24. Attackers can exploit timing measurements using document.caretPositionFromPoint and document.elementFromPoint functions within an IFRAME element to infer sensitive information from cross-origin content, violating the browser's security boundary.

MitigationUpgrade Firefox to version 27.0 or later, and SeaMonkey to version 2.24 or later, to obtain the security patch that addresses this SOP bypass.

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. Identify the installed browser
    Check the browser name and version. In Firefox, go to Help > About Firefox. In SeaMonkey, go to Help > About SeaMonkey.
    Affected if The browser is Mozilla Firefox or Mozilla SeaMonkey
  2. Check Firefox version
    For Firefox, run 'firefox --version' or check Help > About Firefox. Compare the version number to 27.0.
    Affected if Firefox version is lower than 27.0 (e.g., 26.x, 25.x, etc.)
  3. Check SeaMonkey version
    For SeaMonkey, run 'seamonkey --version' or check Help > About SeaMonkey. Compare the version number to 2.24.
    Affected if SeaMonkey version is lower than 2.24 (e.g., 2.23, 2.22, etc.)

You are affected if you are running Mozilla Firefox below version 27.0 or Mozilla SeaMonkey below version 2.24 on the listed platforms.
