Assessment
Why it matters
EPSS is 0.9%; technical severity is CVSS 9.8.
IBM HMC V10.3.1050.0 through 10.3.1064.0 and IBM HMC V11.1.1110.0 through 11.1.1112.0 Management systems in IBM Power environments (HMC and Novalink) could allow an unauthenticated user to execute arbitrary commands with elevated privileges on the system due to improper validation of user supplied input.
Who should care
- Teams operating Hardware Management Console
- Vulnerability and exposure management teams
