V8 - Authorization Unnecessary privilege execution
Exploitation Conditions

Attacker must already have local, authenticated low-privileged shell access (CVSS AV:L/PR:L) on a Unix host running a vulnerable Automic Automation Agent (Linux x64, Linux Power 64 BE/LE, zLinux, AIX, Solaris x64, or Solaris Sparc 64) at a version below 24.4.4 HF1, and the agent must be configured to invoke or be reachable by target programs running with elevated privileges - the core trigger per the description is the agent's execution with unnecessary privileges combined with the presence of elevated-privilege target programs it can act upon. Exploitation is limited by the requirement for a pre-existing local account on the agent host and is not reachable over the network in the default vector; remote attackers would first need to obtain a shell through a separate weakness.

Impact

Real-world risk is moderately high but bounded by the local attack vector. The CVSS 4.0 vector AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H confirms an authenticated local user with low privileges can fully compromise confidentiality, integrity, and availability with low complexity and no user interaction, and the subsequent system scope impacts (SC:L/SI:L/SA:L) indicate limited spill-over to other components. No EPSS score, KEV listing, or POC was provided in the intelligence set, and the CVE is not flagged as actively exploited, suggesting opportunistic rather than mass-exploited risk. Priority should be elevated on hosts where the Automic agent is reachable by low-trust local accounts (e.g., shared batch hosts or jump boxes) and lower where only operators have shell access; missing EPSS and exploit-maturity data (E:X) means real-world exploitation likelihood cannot be independently quantified from the supplied data.

Exploit ScenarioDerived

A low-privileged local user on a Solaris or Linux host where the Automic Automation Agent is deployed leverages the agent's unnecessary privileges to coerce it into launching or influencing a target program that runs with elevated rights, escalating to that program's identity (often root or a service account). With no public exploit identified at time of analysis, the attack would currently require independent vulnerability research, but the low attack complexity and absence of user interaction make weaponization straightforward once internals are understood.

AnalysisAIv1 – May 19, 2026

Local privilege escalation in Broadcom Automic Automation Agent versions prior to 24.4.4 HF1 allows authenticated low-privileged users on Unix-family systems (Linux x64, Linux Power 64 BE/LE, zLinux, AIX, Solaris x64, Solaris Sparc 64) to abuse the agent's elevated privileges and target programs running with higher rights. The CVSS 4.0 score of 8.5 reflects high confidentiality, integrity, and availability impact achievable from a local foothold, with no public exploit identified at time of analysis.

RemediationAI

Vendor-released patch: Automic Automation 24.4.4 HF1 - upgrade all Unix agents to this version or later per the Broadcom Security Advisory at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/37512. If immediate patching is not feasible, restrict interactive and SSH access to hosts running the agent so that only trusted operators hold local accounts, audit the UID/GID and setuid configuration the agent runs under to ensure it does not exceed what jobs actually require, and review agent job definitions to remove or scope target-program invocations that run with root or other elevated identities; note that tightening the agent's identity may break workflows that rely on it executing privileged commands, so workload changes should be staged in a test environment first.

Technical ContextAI · show details

Automic Automation is Broadcom's enterprise workload automation platform; its Unix agent executes scheduled jobs and orchestrates tasks across heterogeneous server fleets, typically running with elevated rights so it can launch processes as multiple target users. The root cause is classified as CWE-250 (Execution with Unnecessary Privileges), meaning the agent retains or exposes privileges broader than required for its operating context, enabling a local attacker to leverage the agent to invoke or influence privileged target programs. The CPE cpe:2.3:a:broadcom:automic_automation:*:*:*:*:*:*:*:* confirms the flaw is in the application layer across all listed Unix-variant builds rather than in an underlying OS component.

DescriptionCVE.org

Execution with unnecessary privileges vulnerability in Broadcom Automic Automation Agent Unix on Linux x64, Linux Power 64 BE, Linux Power 64 LE, zLinux (zSeries), AIX, Solaris x64, Solaris Sparc 64 allows Privilege Escalation, Target Programs with Elevated Privileges.

This issue affects Automic Automation: < 24.4.4 HF1.

Executive ViewAI

Why It Matters

Broadcom Automic Automation Agent contains a local privilege escalation flaw (CVE-2026-8370, CVSS 8.5) affecting versions prior to 24.4.4 HF1 on Unix systems, allowing authenticated low-privilege users to gain elevated access. This exposes organizations running business-critical automation workflows to potential compromise of system integrity and business process continuity, as low-level operators could escalate to administrative control.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: enforce principle of least privilege for automation agent service accounts, implement mandatory access controls (MAC) on affected Unix systems, deploy host-based intrusion detection focusing on local privilege escalation patterns, restrict SSH and direct system access to automation infrastructure, and maintain audit logging of authentication and escalation attempts.

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
