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
The administrative web server on the Digital Alert Systems DASDEC EAS device through 2.0-2 and the Monroe Electronics R189 One-Net EAS device through 2.0-2 uses predictable session ID values, which makes it easier for remote attackers to hijack sessions by sniffing the network. NOTE: VU#662676 states "Monroe Electronics could not reproduce this finding.

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 administrative web interface on Digital Alert Systems DASDEC and Monroe Electronics R189 One-Net EAS devices (versions through 2.0-2) uses cryptographically weak, predictable session ID generation. An attacker who can sniff network traffic can deduce valid session IDs and hijack authenticated administrative sessions.

MitigationImplement cryptographically secure random session ID generation using a CSPRNG; consider implementing session timeout and IP binding as additional session integrity controls. Since this is embedded firmware, contact vendors for patched firmware releases.

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 device model
    Access the administrative web interface or check the device label/documentation to confirm the device is a Digital Alert Systems DASDEC or Monroe Electronics R189 One-Net EAS encoder.
    Affected if The device is a DASDEC or Monroe Electronics R189 One-Net EAS device.
  2. Check the firmware version
    Log into the administrative web interface and navigate to the System Status or About page to view the installed firmware version. Alternatively, check the version displayed on the device's front panel diagnostic display.
    Affected if The firmware version is 2.0-2, 2.0-1, or 2.0-0 (any version through 2.0-2).
  3. Verify the web interface is enabled
    Attempt to access the administrative web interface by entering the device IP address in a web browser. Confirm the login page loads.
    Affected if The administrative web interface is accessible over the network.
  4. Inspect session ID characteristics
    Log into the web interface and examine the session cookie or URL parameter used for session management. Check if session IDs appear sequential, time-based, or have predictable patterns.
    Affected if Session IDs show predictable patterns such as sequential numbering, timestamps, or low-entropy values.

If the device is a DASDEC or Monroe Electronics R189 One-Net EAS with firmware version 2.0-2 or earlier and the administrative web interface is network-accessible, the environment is affected by this vulnerability.

dbcve · scoped
Upgrade available Upgrade to a release after 2.0-2
Interim mitigation

Implement cryptographically secure random session ID generation using a CSPRNG; consider implementing session timeout and IP binding as additional session integrity controls. Since this is embedded firmware, contact vendors for patched firmware releases.

Recommended fix Moderate confidence

Any firmware version higher than 2.0-2 (contact vendor for specific fixed release)

  1. Identify the current installed version of the DASDEC EAS or Monroe Electronics R189 One-Net EAS device
  2. Contact Digital Alert Systems or Monroe Electronics to obtain the latest firmware version that addresses this vulnerability
  3. Upgrade the device firmware to a version higher than 2.0-2 (the vendor should provide the specific fixed release)
  4. After upgrade, verify that session ID generation has been improved and is no longer predictable
  5. Monitor vendor security advisories for any additional updates
Caveat Review vendor release notes for any configuration or compatibility changes before upgrading
