CVE-2016-1918
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 · uneditedCross-site scripting (XSS) vulnerability in the Management Console in BlackBerry Enterprise Server (BES) 12 before 12.4.1 allows remote attackers to inject arbitrary web script or HTML via a crafted URL, a different vulnerability than CVE-2016-1917.
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 confidenceAn XSS vulnerability exists in the Management Console of BlackBerry Enterprise Server 12 before version 12.4.1, allowing remote attackers to inject arbitrary web script or HTML through specially crafted URLs. This client-side injection attack could enable session hijacking, credential theft, or malicious content delivery to users of the Management Console.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify BlackBerry Enterprise Server installationCheck system for presence of BlackBerry Enterprise Server software - look for BES-related services, directories, or installed programs named 'BlackBerry Enterprise Server' or 'BES'Affected if BlackBerry Enterprise Server is not found on the system, the CVE does not apply
-
Determine installed BES versionUse system inventory tools, installed programs list, or BES administration tools to find the exact version number of the BlackBerry Enterprise Server installationAffected if Version cannot be determined or is higher than 12.4, the specific CVE likely does not apply
-
Verify Management Console is enabledCheck if the BES Management Console web interface is accessible or configured to be exposed - this is the specific component affected by the XSS vulnerabilityAffected if Management Console is disabled or not accessible, the attack surface for this XSS may be reduced
-
Confirm affected version rangeCompare your installed BES version against the affected range: versions 12.0 through 12.4 are vulnerable; version 12.4.1 and later contain the fixAffected if Installed version is 12.4 or earlier AND Management Console is accessible, the environment is affected by this XSS vulnerability
You are affected if BlackBerry Enterprise Server version 12.4 or earlier is installed AND the Management Console web interface is enabled and accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-provided patch (BES 12.4.1 or later) to address the input validation deficiency in the Management Console. Additionally, implement output encoding and Content Security Policy headers as defense-in-depth measures.
