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
The docshell implementation in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to trigger the loading of a URL with a spoofed baseURI property, and conduct cross-site scripting (XSS) attacks, via a crafted web site that performs history navigation.

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

A vulnerability in the docshell implementation of Mozilla Firefox, Firefox ESR, Thunderbird, and SeaMonkey allows malicious websites to spoof the baseURI property during history navigation, enabling cross-site scripting (XSS) attacks against users.

MitigationApply vendor-supplied security updates to upgrade to Firefox 29.0+, Firefox ESR 24.5+, Thunderbird 24.5+, or SeaMonkey 2.26+ as appropriate.

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. Check Firefox version
    Open Firefox, click Help > About Firefox, or run 'firefox --version' from command line
    Affected if Version is less than 29.0, or between 24.0 and 24.5 (24.0 <= version < 24.5)
  2. Check Firefox ESR version
    Open Firefox ESR, click Help > About Firefox, or check installed package with 'rpm -q firefox-esr' or 'dpkg -l firefox-esr'
    Affected if Version is less than 24.5
  3. Check Thunderbird version
    Open Thunderbird, click Help > About Thunderbird, or run 'thunderbird --version' from command line
    Affected if Version is less than 24.5
  4. Check SeaMonkey version
    Open SeaMonkey, click Help > About SeaMonkey, or run 'seamonkey --version' from command line
    Affected if Version is less than 2.26
  5. Check installed Mozilla package on Linux
    Use package manager: 'rpm -qa | grep -i firefox' (RHEL/Fedora) or 'dpkg -l | grep -i firefox' (Ubuntu/Debian)
    Affected if Package version matches an affected release (Firefox 24.x before 24.5, or versions below 29.0)

A user is affected if they run any Firefox, Firefox ESR, Thunderbird, or SeaMonkey version that falls within the vulnerable ranges: less than 24.5 for ESR/Thunderbird, 24.0-24.4 for Firefox, or less than 29.0 for Firefox.
