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
API endpoint for user synchronization in 2N Access Commander version 3.4.1 did not have a sufficient input validation allowing for OS command injection. This vulnerability can only be exploited after authenticating with administrator privileges.

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

2N Access Commander version 3.4.1 contains an OS command injection vulnerability in the API endpoint for user synchronization due to insufficient input validation. An authenticated administrator can inject arbitrary OS commands through unsanitized input parameters passed to the user sync functionality.

MitigationImplement strict input validation and parameterized queries or sandboxed command execution for the user synchronization API endpoint. Consider using allowlist validation for all user-supplied input and replacing any dynamic command construction with safe API calls.

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 2N Access Commander version
    Locate the version information for your 2N Access Commander installation through the web interface, system diagnostics, or installed packages listing. Common locations include the administration panel's system info section or package management tools.
    Affected if The installed version is 3.4.1 or any version prior to 3.4.2
  2. Verify user synchronization feature is configured
    Check if the user synchronization functionality is enabled in the 2N Access Commander administration interface. Look for settings related to LDAP/AD synchronization, user import, or external identity provider integration.
    Affected if User synchronization is actively configured or has been used recently
  3. Review API access logs for user sync endpoint
    Examine authentication and API access logs for requests to user synchronization endpoints. Look for any entries involving command execution or unusual parameter patterns in sync-related API calls.
    Affected if There are recent API calls to user sync endpoints from administrator accounts with unexpected parameter content
  4. Check for unauthorized administrator accounts
    Review the list of administrator accounts in the system for any unauthorized or unexpected entries that may have been created through the command injection vulnerability.
    Affected if New or unexpected administrator accounts exist that were not created through legitimate administrative actions
  5. Inspect system for unexpected processes or scheduled tasks
    Examine running processes and scheduled tasks on the 2N Access Commander server for any unrecognized or suspicious commands that may have been injected and persisted.
    Affected if Unexpected processes, scripts, or scheduled tasks are present on the system

Your environment is affected if 2N Access Commander version is 3.4.1 or earlier AND the user synchronization feature is enabled, as this combination exposes the vulnerable API endpoint to authenticated administrators.

Upgrade available Upgrade to 3.4.2 or later
Fixed in 3.4.2
Interim mitigation

Implement strict input validation and parameterized queries or sandboxed command execution for the user synchronization API endpoint. Consider using allowlist validation for all user-supplied input and replacing any dynamic command construction with safe API calls.

Recommended fix Moderate confidence

Access Commander 3.4.2

  1. Locate your current 2N Access Commander installation and verify the installed version
  2. Access the 2N official support website or admin console to obtain version 3.4.2
  3. Follow the standard 2N Access Commander upgrade procedure documented in the official administration guide
  4. After upgrading, verify the new version is 3.4.2 or higher
  5. Confirm the API endpoint for user synchronization is now properly sanitizing input
