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
Due to insufficient file permissions, unprivileged users could gain access to unencrypted user credentials that are used in the integration interface towards 3rd party systems.

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

The vulnerability stems from improper file permissions on credential storage files, allowing unprivileged users to read unencrypted credentials used for third-party system integrations. This enables attackers with basic system access to obtain credentials for downstream systems.

MitigationRestrict file permissions on credential storage locations to privileged users/processes only, and encrypt stored credentials at rest.

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 Axis License Plate Verifier installation
    Locate the Axis License Plate Verifier application on the system. Check common installation directories or use system inventory tools to confirm presence of this specific product.
    Affected if The product is not installed on the system.
  2. Determine installed version
    Query the installed version of Axis License Plate Verifier using the product's built-in version command, about dialog, or system registry/tools. Compare the version number to the affected range: 2.8.3 and below.
    Affected if The installed version is 2.8.3 or lower.
  3. Locate credential storage files
    Search for credential storage files used by the Axis License Plate Verifier for third-party system integrations. Common locations may include configuration directories, data folders, or credential vault files associated with the application.
    Affected if Credential storage files exist on the system.
  4. Inspect file permissions on credential storage
    Use filesystem permission tools (such as ls -la or icacls) to examine the access control lists on identified credential storage files. Verify which user accounts and groups have read access to these files.
    Affected if Unprivileged users or the Everyone group have read access to credential storage files.
  5. Verify credential encryption status
    Examine the credential storage files to determine if credentials are stored in encrypted form or in plaintext. Check file contents if permissions allow, or review application configuration for encryption settings.
    Affected if Credentials are stored in plaintext or with weak encryption that could be read by unprivileged users.

A system is affected if Axis License Plate Verifier version 2.8.3 or lower is installed AND credential storage files are readable by unprivileged users due to improper file permissions.
