Unitrends Security: IPMI Port Vulnerabilities


Unitrends Security: IPMI Port Vulnerabilities


In response to potentials for IPMI Port Vulnerabilities
Unitrends Appliances that include IPMI capabilities, are not vulnerable to any of the specified threats because the IPMI solution is disabled by default. If you choose to use the IPMI solution, please review the following information to harden the solution to the needs of your environment and security needs.

Below are the Common Vulnerabilities and Exposures (CVE) numbers that relate to IPMI and how to address them. Any commands that need to be submitted to the BIOS or IPMI can be done by connecting a keyboard and monitor console to the Unitrends Appliance or by via an SSH Terminal Console, using ipmiutil.

The ipmiutil package is pre-installed on systems after Unitrends release 7.2.0, but some systems may have versions prior to ipmiutil-2.9.4, so it can be updated using this command:  yum update ipmiutil.
