CVE-2014-2379
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 · uneditedSensys Networks VSN240-F and VSN240-T sensors VDS before 2.10.1 and TrafficDOT before 2.10.3 do not use encryption, which allows remote attackers to interfere with traffic control by replaying transmissions on a wireless network.
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 confidenceSensys Networks VSN240-F and VSN240-T wireless traffic sensors running VDS before 2.10.1 and TrafficDOT before 2.10.3 transmit data without encryption over wireless networks. Attackers can capture and replay these unencrypted transmissions to manipulate traffic control 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 the installed product and firmware versionAccess the sensor management interface or check the device label to determine if the device is a VSN240-F, VSN240-T, or a system running VDS or TrafficDOT software. Note the exact version number displayed in the system information or about section.Affected if The device is a VSN240-F or VSN240-T (all versions) OR the installed VDS version is 1.8.5, 1.8.7, 2.6.3, 2.6.4, or <= 2.10.0 OR the installed TrafficDOT version is 2.8.3, 2.10.0, 2.10.1, or <= 2.10.2
-
Verify wireless encryption configuration on the sensorLog into the sensor management console or access the wireless network settings. Look for the encryption settings (WPA2, AES, or proprietary encryption) on the wireless interface connecting the sensor to the network.Affected if No encryption is enabled on the wireless interface, or the encryption is set to 'None' or 'Open'
-
Capture and inspect wireless traffic from the sensorUse a wireless packet sniffer (such as Wireshark with a monitor-mode adapter) to capture traffic transmitted by the sensor. Examine the captured packets to determine if the payload data is encrypted or transmitted in plaintext.Affected if Traffic captures show unencrypted, plaintext data in the sensor transmissions (data appears as readable text rather than encrypted bytes)
-
Check for replay attack vulnerability in network monitoringReview wireless intrusion detection system (WIDS) logs or network monitoring tools for any signs of repeated or duplicated sensor transmissions that could indicate a replay attack attempt.Affected if Duplicate sensor transmissions are detected on the network, or no replay attack detection mechanisms are in place
A user is affected if their device is a VSN240-F or VSN240-T (any version) or runs a vulnerable VDS/TrafficDOT version AND wireless encryption is not enabled or traffic is transmitted in plaintext.

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 dataUpgrade VDS to version 2.10.1 or later and TrafficDOT to version 2.10.3 or later to enable encryption. If immediate upgrade is not feasible, implement network segmentation and employ wireless intrusion detection to monitor for replay attacks on the sensor network.
