Remediations

• Bachmann recommends its direct users and original equipment manufacturers (OEM) update to Version 4.49-P1, which is available under item number 00036634-90. To obtain Version 3.95R-P8 the end user is required to contact their key account manager or technical support agent at Bachmann. Asset owners should contact their OEM or reseller for patches. Bachmann does not provide support directly to asset owners. Please refer to the Bachmann Customer Information Note for more details. The password “_pC5#3fS@Y8s” is required to access.
• Update the default username and password in the default Bachmann login handler for field operations.
• Direct users or OEMs may utilize their own login handler (e.g., LDAP, Radius, etc.) to circumvent the default authentication handler. Security Level 4 is still recommended for field operations.
• Restrict physical access to the device to authorized personnel only.
• Default Security Level 0 within Bachmann controllers is inherently insecure and should not be used in field operations. Security Levels 1, 2, and 3 are also not recommended for field operations. The use of Telnet, FTP, and Console access during field operations may result in the exploitation of inherent vulnerabilities such as unauthenticated access or exposure of sensitive information. Bachmann strongly recommends users apply Security Level 4, where communication with the device is limited to TLS protected services and all insecure services are disabled.
