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
Specially constructed queries cause cross platform scripting leaking administrator tokens

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 cross-site scripting (XSS) vulnerability where specially crafted queries injected into the application can execute malicious scripts in administrators' browsers, allowing theft of session tokens and unauthorized administrative access.

MitigationImplement context-sensitive output encoding and input validation for all user-supplied data; additionally, enforce strict Content Security Policy (CSP) headers and consider implementing anti-CSRF tokens to protect administrator sessions.

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 Arista Ng Firewall installation
    Locate the firewall appliance or software and confirm it is running Arista Ng Firewall product
    Affected if The system is not Arista Ng Firewall
  2. Check installed Ng Firewall version

    Affected if The installed version is any version prior to 17.2 (e.g., 17.1.x, 17.0.x, earlier releases)
  3. Verify admin interface exposure
    Confirm whether the administrative web interface is accessible to network users or the internet
    Affected if The admin interface is reachable by untrusted users or directly exposed to the internet

A user is affected if they are running any version of Arista Ng Firewall prior to version 17.2 with an accessible administrative interface.
