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
2N Access Commander version 2.1 and prior is vulnerable in default settings to Man In The Middle attack due to not verifying certificates of 2N edge devices. 2N has currently released an updated version 3.3 of 2N Access Commander, with added Certificate Fingerprint Verification. Since version 2.2 of 2N Access Commander (released in February 2022) it is also possible to enforce TLS certificate validation.It is recommended that all customers update 2N Access Commander to the latest version and use one of two mentioned practices.

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 versions 2.1 and prior do not verify TLS certificates from connected 2N edge devices in their default configuration, allowing an attacker positioned on the network to intercept and modify communications between the Access Commander server and edge devices via a Man-In-The-Middle attack.

MitigationUpgrade to version 3.3 or later which includes Certificate Fingerprint Verification, or at minimum upgrade to version 2.2 and enable TLS certificate validation enforcement.

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 the installed 2N Access Commander version
    Access the web administration interface and navigate to the About or System Information page, or check the version displayed on the login screen. Alternatively, check any installed software inventory or documentation.
    Affected if The displayed version is 2.1 or any version prior to 2.1
  2. Verify whether TLS certificate validation is enabled
    In the web administration interface, locate the TLS or security settings section. Look for options related to certificate verification, certificate fingerprint validation, or TLS authentication for edge device connections.
    Affected if Certificate validation is disabled, not configured, or set to 'optional' in the current configuration
  3. Confirm the default configuration state
    Review the current security configuration to determine if the installation has ever had TLS certificate validation explicitly enabled, or if it has always operated with default settings.
    Affected if The system is using default settings with no explicit TLS certificate validation configured for edge device communications
  4. Check the connected edge device configuration
    In the device management or edge device settings section, verify whether the server is configured to validate certificates or fingerprints from connected 2N edge devices.
    Affected if The server does not require or verify TLS certificates from edge devices before establishing connections

The environment is affected if 2N Access Commander version 2.1 or prior is in use with default settings where TLS certificate validation for edge devices is disabled or not enforced.

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

Upgrade to version 3.3 or later which includes Certificate Fingerprint Verification, or at minimum upgrade to version 2.2 and enable TLS certificate validation enforcement.

Recommended fix High confidence

2N Access Commander version 3.3

  1. Download 2N Access Commander version 3.3 from the official 2N website (www.2n.com)
  2. Follow the 2N upgrade documentation to upgrade from version 2.1 or prior to version 3.3
  3. After upgrading to version 3.3, enable Certificate Fingerprint Verification in the settings
  4. Alternatively, if staying on version 2.2 or later, enforce TLS certificate validation in the configuration settings
  5. Verify that certificate validation is active by testing connectivity to 2N edge devices
