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
**VERSION NOT SUPPORTED WHEN ASSIGNED** A vulnerability could cause certain data to be visible on the network when the 'password' feature is enabled. This vulnerability was discovered in and remediated in versions v4.9.1 and v4.10.1 on May 30, 2013. The 'password' feature is an additional optional check performed by TS1131 that it is connected to a specific controller. This data is sent as clear text and is visible on the network. This feature is not present in TriStation 1131 versions v4.9.1 and v4.10.1 through current. Therefore, the vulnerability is not present in these versions.

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 confidence

In older versions of TriStation 1131 (before v4.9.1/v4.10.1), the optional 'password' feature used to verify connection to a specific controller transmitted authentication data in cleartext on the network, allowing eavesdroppers to capture sensitive information.

MitigationUpgrade TriStation 1131 to version v4.9.1, v4.10.1, or later, which removed the vulnerable password feature entirely.

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 installed TriStation 1131 version
    Locate the TriStation 1131 installation on the system and check the software version information, typically found in the program metadata, about dialog, or installation directory
    Affected if Version is between 1.0 and 4.12.0 inclusive
  2. Compare version to affected range
    Verify if the identified version falls within the vulnerable range: >= 1.0 and <= 4.12.0
    Affected if Version is 4.12.0 or lower
  3. Check if password feature is configured
    Examine the TriStation 1131 project or controller configuration settings to determine whether the optional password feature for controller connection has been enabled
    Affected if Password feature is enabled and configured for controller communication

Environment is affected if TriStation 1131 version 4.12.0 or lower is installed AND the optional password feature is configured for controller connection.
