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
Ericsson Network Manager (ENM), versions prior to 22.1, contains a vulnerability in the application Network Connectivity Manager (NCM) where improper Neutralization of Formula Elements in a CSV File can lead to remote code execution or data leakage via maliciously injected hyperlinks. The attacker would need admin/elevated access to exploit the 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

Ericsson Network Manager (ENM) versions before 22.1 contain a CSV injection vulnerability in the Network Connectivity Manager (NCM) component. Attackers with admin/elevated access can inject formula characters (=, +, -, @, tab) into CSV exports that, when opened in spreadsheet applications, can trigger arbitrary code execution or data exfiltration.

MitigationEscape or remove formula-initiating characters (=, +, -, @, tab, carriage return) from user-controlled data before embedding in CSV exports, or implement warning banners in generated CSV files to alert users of potentially dangerous content.

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 ENM installation version
    Access the ENM administrative interface or check system inventory for the installed Ericsson Network Manager version number. Compare against the affected range of versions before 22.1.
    Affected if The installed version is lower than 22.1 (e.g., 21.x, 20.x, etc.)
  2. Confirm Network Connectivity Manager (NCM) component is present
    Check ENM deployment documentation or component list to verify the NCM module or feature is installed and active.
    Affected if NCM component is present in the ENM deployment
  3. Verify CSV export functionality exists
    Locate the Network Connectivity Manager interface and identify if CSV export or download features are available for network data or reports.
    Affected if CSV export feature is accessible within the NCM component
  4. Assess user access to NCM export feature
    Review user role permissions in ENM to determine if admin or elevated-privilege accounts exist that can access the CSV export functionality.
    Affected if Admin or elevated-privilege accounts with access to CSV export are present in the system

The environment is affected if running Ericsson Network Manager version below 22.1 with the NCM component and CSV export feature enabled, allowing admin users to generate CSV files that could contain injected formula characters.

Escape or remove formula-initiating characters (=, +, -, @, tab, carriage return) from user-controlled data before embedding in CSV exports, or implement warning banners in generated CSV files to alert users of potentially dangerous content.

Recommended fix High confidence

22.1

  1. Upgrade Ericsson Network Manager (ENM) to version 22.1 or later to address the CSV formula injection vulnerability.
  2. Verify the upgrade in a test environment before deploying to production.
  3. After upgrading, confirm that the Network Connectivity Manager (NCM) component is functioning correctly with the new version.
