No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

An issue was discovered in SecurEnvoy SecurAccess 9.3.502. When put in Debug mode and used for RDP connections, the application stores the emergency credentials in cleartext in the logs (present in the DEBUG folder) that can be accessed by anyone. NOTE: The vendor disputes this as a vulnerability since the disclosure of a local account password (actually an alpha numeric passcode) is achievable only when a custom registry key is added to the windows registry. This action requires administrator access and the registry key is only provided by support staff at securenvoy to troubleshoot customer issues.
