Who should care

Organizations operating Johnson Controls Software House C●CURE 9000 physical access control systems, particularly those with web server interfaces exposed to administrative users. Security teams responsible for OT/ICS environments, building automation systems, and credential management programs should prioritize assessment and remediation.

Technical summary

The C●CURE 9000 Web Server, hosted on Microsoft IIS, can log Windows credential details to local log files under certain conditions. This information disclosure occurs in the api.log file located at C:/Program Files (x86)/Tyco/victorWebServices/victorWebsite/Logs. The vulnerability requires local access and high privileges to exploit, but successful exploitation yields high impact to confidentiality and integrity with some availability impact. Non-web service interfaces and prior product versions are explicitly noted as unaffected.

Defensive priority

HIGH

Recommended defensive actions

  • Apply vendor fix: Update Software House C●CURE 9000 to version 3.00.2 CU02 or 3.00.3.
  • Rotate credentials: Change passwords for any Windows accounts whose credentials may have been logged.
  • Sanitize logs: Delete the api.log file or manually remove password instances from C:/Program Files (x86)/Tyco/victorWebServices/victorWebsite/Logs.
