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
OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules rely exclusively on a time value for entropy in key generation, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by predicting the time of project creation.

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 OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules use only a timestamp as the entropy source for cryptographic key generation. Since project creation time can be predicted or discovered by attackers, the encryption keys can be reconstructed, allowing remote attackers to defeat the cryptographic protection mechanisms.

MitigationReplace time-based key generation with cryptographically secure random number generators (CSPRNG) and implement proper key management. If firmware update available from vendor, apply it; otherwise implement out-of-band key provisioning.

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 OleumTech devices in your environment
    Inventory network-connected devices and look for OleumTech WIO DH2 Wireless Gateway or Sensor Wireless I/O Modules. Check device labels, network scans, or asset management records for these specific product names.
    Affected if OleumTech WIO DH2 Wireless Gateway or Sensor Wireless I/O Modules are present in the environment
  2. Confirm device firmware version
    Access the device management interface or check device documentation to determine the firmware version installed on OleumTech WIO or Sensor modules.
    Affected if Any firmware version is found on these devices - all versions are affected by design
  3. Examine cryptographic key provisioning method
    Review device configuration settings, key management documentation, or consult vendor documentation to determine how encryption keys are generated. Check if keys are derived from timestamp/creation time or if out-of-band key provisioning with cryptographically random keys has been implemented.
    Affected if Keys are generated using timestamp as the sole entropy source or default factory settings are in use without custom key provisioning
  4. Verify custom key implementation
    Check if organization has implemented out-of-band key provisioning (keys generated externally using CSPRNG and imported into devices) instead of relying on device-generated time-based keys.
    Affected if No custom key provisioning has been implemented and devices rely on default key generation behavior

If OleumTech WIO DH2 Wireless Gateway or Sensor Wireless I/O Modules are deployed using the default timestamp-based key generation without out-of-band key provisioning, the environment is affected by CVE-2014-2362.

Mitigation

Replace time-based key generation with cryptographically secure random number generators (CSPRNG) and implement proper key management. If firmware update available from vendor, apply it; otherwise implement out-of-band key provisioning.
