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
Combodo iTop is a simple, web based IT Service Management tool. When displaying page Run queries Cross-site Scripting (XSS) are possible for scripts outside of script tags. This has been fixed in versions 2.7.9, 3.0.4, 3.1.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.

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

Combodo iTop contains a stored Cross-site Scripting (XSS) vulnerability in the 'Run queries' page where malicious scripts can be injected and executed outside of script tags. This allows attackers to embed malicious JavaScript that executes in the browsers of users viewing the affected page.

MitigationUpgrade iTop to version 2.7.9, 3.0.4, or 3.1.0 to patch the XSS vulnerability. No workarounds are available.

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 installed iTop version
    Locate the version file or check the application footer/admin page for the exact version number of Combodo iTop
    Affected if The version is below 2.7.9, or between 3.0.0 and 3.0.4 inclusive
  2. Confirm Run queries feature is accessible
    Navigate to or check if the 'Run queries' page is present in the iTop web interface (typically under the Queries or Data menu)
    Affected if The Run queries page exists and is accessible to the user being assessed
  3. Verify query execution capability
    Check if the logged-in user has permissions to create or modify queries in the Run queries interface
    Affected if Users with query creation/modification privileges can access this feature
  4. Inspect stored query definitions
    Examine the database tables (such as priv_query or similar) or the Run queries page for any unexpected or suspicious query names or values that may contain script tags or HTML attributes
    Affected if Any query entries contain unsanitized user input that could execute as JavaScript

You are affected if your iTop version is below 2.7.9 or between 3.0.0-3.0.4 AND the Run queries feature is accessible to users in your environment.

Recommended fix High confidence

iTop 2.7.9 (for 2.x users) or iTop 3.0.4/3.1.0 (for 3.x users)

  1. Determine your current iTop version by checking the application's login page or configuration
  2. If running iTop 2.x (version < 2.7.9), upgrade to version 2.7.9 or later (e.g., 2.7.9)
  3. If running iTop 3.0.x (version >= 3.0.0 and < 3.0.4), upgrade to version 3.0.4 or later (recommended: 3.1.0)
