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
When user authentication is not enabled the shell can execute commands with the highest privileges. Red Lion SixTRAK and VersaTRAK Series RTUs with authenticated users enabled (UDR-A) any Sixnet UDR message will meet an authentication challenge over UDP/IP. When the same message comes over TCP/IP the RTU will simply accept the message with no authentication challenge.

Recommended fix Moderate confidence

RLCSIM-2023-05 patch/firmware update (contact vendor for exact version per model)

  1. Identify your specific Red Lion SixTRAK or VersaTRAK model from the affected list (St Ipm 6350, St Ipm 8460, Vt Mipm 135 D, Vt Mipm 245 D, Vt Ipm2m 213 D, or Vt Ipm2m 113 D)
  2. Navigate to the vendor support portal at https://support.redlion.net
  3. Locate the RLCSIM-2023-05 patch or firmware update for your specific model
  4. Download and apply the firmware update to address the authentication bypass vulnerability
  5. After patching, verify that user authentication (UDR-A) is properly enabled
  6. Confirm that both UDP/IP and TCP/IP communications now properly enforce authentication challenges
