CVE-2024-51995
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 · uneditedCombodo iTop is a web based IT Service Management tool. An attacker can request any `route` we want as long as we specify an `operation` that is allowed. This issue has been addressed in version 3.2.0 by applying the same access control pattern as in `UI.php` to the `ajax.render.php` page which does not allow arbitrary `routes` to be dispatched. 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 confidenceCombodo iTop contains an access control bypass vulnerability in ajax.render.php where an attacker can specify arbitrary routes as long as the requested operation is allowed. The fix applies the same access control pattern from UI.php to prevent unauthorized route dispatching.

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 installed iTop versionLocate the iTop version file or header in the installation directory and read the version numberAffected if The installed version is lower than 3.2.0
-
Verify ajax.render.php existsLocate the ajax.render.php file in the web-facing iTop directoryAffected if The file exists and is accessible via the web server
-
Check if access controls from UI.php were applied to ajax.render.phpCompare the access control implementation in ajax.render.php to the pattern used in UI.php - look for route dispatching authorization checksAffected if ajax.render.php lacks the same access control checks that UI.php implements for route dispatching
-
Confirm ajax.render.php is web accessibleAttempt to access ajax.render.php via HTTP/HTTPS from the web serverAffected if The file responds to web requests without proper authorization enforcement
The environment is affected if iTop version is below 3.2.0 AND ajax.render.php is accessible without the UI.php-style access controls on route dispatching.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped3.2.0
Upgrade to iTop version 3.2.0 or later which enforces proper access controls on ajax.render.php. No workarounds are available.
3.2.0
- Download iTop version 3.2.0 from the official Combodo repository or your customer portal
- Review the iTop upgrade documentation for your current version
- Create a complete backup of your iTop installation including the database
- Place the site in maintenance mode if applicable
- Extract and deploy the new 3.2.0 files to your web server
- Run the iTop setup/upgrade wizard to migrate the database schema
- Verify the upgrade was successful by logging in and testing core functionality
- Ensure the ajax.render.php file contains the access control fix that restricts route dispatching
