Attack Chain

1. A local attacker gains initial access to a system running the vulnerable Broadcom Automic Automation Agent for Unix.
2. The attacker identifies a weakness within the agent’s permissioning or execution logic.
3. The attacker crafts a malicious input or command specifically designed to exploit the identified vulnerability.
4. The attacker executes the malicious command, leveraging the agent’s existing privileges in an unintended way.
5. Through the exploited vulnerability, the attacker gains elevated privileges, such as root or system administrator.
6. The attacker leverages the escalated privileges to access sensitive data, modify system configurations, or install malicious software.
7. The attacker may further compromise the system by creating new user accounts with elevated privileges for persistent access.

Impact

Successful exploitation of this vulnerability allows a local attacker to escalate privileges on a Unix system running the Broadcom Automic Automation Agent. This could lead to complete compromise of the system, unauthorized access to sensitive data handled by the automation agent, and potential lateral movement to other systems within the network. The specific impact depends on the agent’s configuration and the privileges it operates with, but could include disrupting critical business processes.

Recommendation

• Investigate all systems running Broadcom Automic Automation Agent Unix for any suspicious activity indicative of privilege escalation (see Sigma rule below).
• Monitor process execution for unexpected commands or processes being run by the Automic Automation Agent (see Sigma rule below).
• Apply the latest security patches released by Broadcom for Automic Automation Agent Unix as soon as they are available to remediate the underlying vulnerability.
