Who should care

Administrators and operators running Automic Automation Agent Unix on Linux x64, Linux Power 64 BE/LE, zLinux (zSeries), AIX, Solaris x64, or Solaris Sparc 64; security teams responsible for patching and privilege-hardening on those hosts.

Technical summary

The CVE description indicates an execution-with-unnecessary-privileges flaw in the Automic Automation Agent Unix component. NVD assigns CVSS 4.0 AV:L/AC:L/AT:N/PR:L/UI:N with high impact to confidentiality, integrity, and availability, which is consistent with a local privilege-escalation path. The issue affects Automic Automation versions prior to 24.4.4 HF1.

Defensive priority

High — prioritize remediation on any affected host, especially where the agent runs with elevated privileges.

Recommended defensive actions

  • Inventory Automic Automation Agent Unix deployments and identify versions earlier than 24.4.4 HF1.
  • Upgrade to 24.4.4 HF1 or a later vendor-fixed release as soon as possible.
  • Review agent service accounts and remove unnecessary elevated privileges where operationally feasible.
  • Monitor affected hosts for unexpected child processes, command execution, or privilege changes associated with the agent.
  • Follow the Broadcom advisory and validate any compensating controls against your deployment model.
