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
CSV injection in export as csv in Combodo iTop v.3.1.0-2-11973 allows a local attacker to execute arbitrary code via a crafted script to the export-v2.php and ajax.render.php components.

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

CSV injection vulnerability in Combodo iTop's export functionality (export-v2.php and ajax.render.php) allows a local attacker to inject malicious formulas into CSV exports. When opened in spreadsheet applications, these crafted formulas can execute arbitrary code on the victim's system.

MitigationImplement input sanitization to escape or strip formula injection characters (=, +, -, @, tab, CR) from user-supplied data before including it in CSV exports. Consider disabling macro execution in generated CSV files or using proper content-type headers.

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 iTop installation and version
    Locate the iTop installation directory and check the version file (typically version.php or similar file containing the version string). Compare the installed version to the affected version 3.1.0-2 build 11973.
    Affected if The installed iTop version is 3.1.0-2 build 11973 or lower.
  2. Confirm export-v2.php exists
    Check if the file export-v2.php exists in the web root or application directory of the iTop installation.
    Affected if The file export-v2.php is present and accessible on the server.
  3. Confirm ajax.render.php exists
    Check if the file ajax.render.php exists in the iTop application directory.
    Affected if The file ajax.render.php is present and accessible on the server.
  4. Verify CSV export functionality is enabled
    Access the iTop web interface and attempt to use the export feature (typically found in the Data Administration or Export menu). Check if users with appropriate permissions can generate CSV exports.
    Affected if The CSV export functionality is enabled and accessible to users.
  5. Test for formula injection character handling
    Create a test object in iTop with a field containing a formula injection character (=, +, -, @, tab, or CR) followed by text (e.g., '=CMD|'). Export that object to CSV and examine the raw CSV content to see if the character is escaped or stripped.
    Affected if The formula injection characters are NOT escaped or stripped in the CSV export output (raw CSV shows unescaped =, +, -, @, or similar characters).

A user is affected if they are running Combodo iTop version 3.1.0-2 build 11973 or lower AND have the CSV export functionality enabled, with unescaped formula injection characters appearing in exported CSV files.

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
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement input sanitization to escape or strip formula injection characters (=, +, -, @, tab, CR) from user-supplied data before including it in CSV exports. Consider disabling macro execution in generated CSV files or using proper content-type headers.
