CVE-2014-9194
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 · uneditedArbiter 1094B GPS Substation Clock allows remote attackers to cause a denial of service (disruption) via crafted radio transmissions that spoof GPS satellite broadcasts.
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 confidenceThe Arbiter 1094B GPS Substation Clock accepts GPS satellite signals without sufficient validation, allowing remote attackers to transmit crafted radio signals that spoof legitimate GPS broadcasts and cause the device to lose synchronization or provide incorrect time, resulting in denial of service for time-dependent substation operations.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Arbiter 1094B device in environmentLocate the physical device or check network inventory for 'Arbiter 1094B' or '1094B GPS Substation Clock' - this may require physical inspection of telecom/network closets or DCIM recordsAffected if The device is present and operational in the environment
-
Verify GPS signal reception is activeCheck device status indicators or management interface for GPS signal lock status - look for 'GPS Locked', 'Synchronized', or signal strength indicators on the device front panel or web interfaceAffected if GPS signal is being received and the device shows locked/synchronized status, meaning it is vulnerable to spoofed signals
-
Check network accessibility of device management interfaceDetermine if the device management port (typically Ethernet for configuration/monitoring) is accessible from network segments - check for open ports 80/443 or SNMP exposureAffected if The device management interface is reachable from network segments beyond the isolated control room, increasing attack surface for remote exploitation
-
Monitor for time synchronization anomaliesCompare device time output against known-good authoritative time sources (such as local atomic clock, PTP grandmaster, or other trusted NTP servers) over a period - log any sudden jumps, step changes, or gradual driftAffected if Time discrepancies are detected when compared against independent time references, indicating possible spoofing or loss of synchronization
-
Inspect for GPS spoofing detection capabilitiesReview device configuration or documentation for any available GPS signal validation, anti-spoofing, or cryptographic authentication settings - check firmware version and available security featuresAffected if Device lacks GPS signal authentication or spoofing detection features, or such features are disabled (note: all versions are affected regardless)
If an Arbiter 1094B GPS Substation Clock is present and actively receiving GPS signals, the environment is affected by this vulnerability since all versions lack sufficient GPS signal validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement GPS signal spoofing detection and monitoring solutions, deploy cryptographic GPS signal authentication if available from vendor, and segregate critical timing infrastructure on restricted network segments with redundant authoritative time sources.
