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
In Combodo iTop 2.2.0 through 2.6.0, if the configuration file is writable, then execution of arbitrary code can be accomplished by calling ajax.dataloader with a maliciously crafted payload. Many conditions can place the configuration file into a writable state: during installation; during upgrade; in certain cases, an error during modification of the file from the web interface leaves the file writable (can be triggered with XSS); a race condition can be triggered by the hub-connector module (community version only from 2.4.1 to 2.6.0); or editing the file in a CLI.

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

Arbitrary code execution vulnerability in Combodo iTop 2.2.0-2.6.0 where an attacker can execute malicious code via ajax.dataloader if the configuration file is writable. Multiple conditions (installation, upgrade, XSS-triggered errors, hub-connector race condition, or CLI editing) can leave the config file in a writable state.

MitigationEnsure the configuration file has restrictive filesystem permissions (not writable by the web server process) and apply vendor patches to prevent code execution via ajax.dataloader.

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 banner to determine the running iTop version number
    Affected if the installed version falls within 2.2.0 to 2.4.0 or 2.4.1 to 2.6.0
  2. Locate the main configuration file
    Find the primary configuration file (commonly config.php or similar in the application root or conf directory)
    Affected if you cannot locate a configuration file to check
  3. Check if configuration file is writable
    Inspect filesystem permissions on the main configuration file - on Unix systems use 'ls -la' or 'stat', on Windows check the file properties under Security tab
    Affected if the configuration file has write permissions enabled for the web server user or World/Group writable permissions (e.g., permission mask 0666 or 0777, or owner writable by non-admin user)
  4. Verify ajax.dataloader endpoint accessibility
    Determine if the ajax.dataloader script is accessible via HTTP/HTTPS on the web server - attempt a request or check web server routing configuration
    Affected if the ajax.dataloader endpoint is reachable without authentication

You are affected if running iTop 2.2.0-2.6.0 AND the configuration file is writable by the web server process AND ajax.dataloader is accessible, allowing remote code execution.

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 data
Upgrade available Upgrade to a release after 2.6.0
Interim mitigation

Ensure the configuration file has restrictive filesystem permissions (not writable by the web server process) and apply vendor patches to prevent code execution via ajax.dataloader.
