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
An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Juniper Networks Junos Space allows an attacker to inject script tags in the Template Definition page, when visited by another user, enables the attacker to execute commands with the target's permissions, including an administrator.This issue affects all versions of Junos Space before 24.1R4.

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 stored cross-site scripting (XSS) vulnerability in Juniper Junos Space's Template Definition page allows authenticated attackers to inject malicious script tags. When other users (including administrators) view the compromised page, the injected scripts execute with the victim's permissions, enabling command execution.

MitigationUpgrade Junos Space to version 24.1R4 or later to remediate this vulnerability.

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 Junos Space installation
    Review your system inventory or check for Juniper Junos Space running on your network. Access the web interface or check via system commands.
    Affected if Juniper Junos Space software is present in your environment
  2. Determine installed Junos Space version
    Log into the Junos Space web interface and navigate to the About or System Information page, or use the CLI command 'show version' if available via SSH.
    Affected if Installed version is any version prior to 24.1, or exactly version 24.1
  3. Verify Template Definition page accessibility
    Navigate to the Template Definition page within the Junos Space web interface (typically under Network Management or Templates sections). Confirm the page loads and is accessible to authenticated users.
    Affected if Template Definition page is accessible and functional in your installation
  4. Inspect Template Definition page for injected content
    Use browser developer tools (F12) or view the page source of the Template Definition page. Look for any unexpected script tags, iframe elements, or obfuscated JavaScript in the HTML source.
    Affected if Unexpected script tags or malicious code is present in the rendered page source

Your environment is affected if Junos Space is installed and the version is less than 24.1 or exactly 24.1, and the Template Definition page is accessible to authenticated users.
