Remote Code Execution in HPE Networking Fabric Composer

Publication date: 2026-09-01

Last updated on: 2026-09-02

Assigner: Hewlett Packard Enterprise (HPE)

Description

A remote code execution vulnerability exists in the underlying operating system of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system, leading to complete compromise of the HPE Networking Fabric Composer host.

Attack-Flow Graph

Executive Summary

This is a remote code execution vulnerability in HPE Networking Fabric Composer's underlying operating system. An unauthenticated remote attacker could exploit it to run arbitrary commands on the host if certain external conditions are met. Successful exploitation grants privileged command execution, potentially leading to full system compromise.

Detection Guidance

Detection of this vulnerability requires checking for unauthorized command execution on HPE Networking Fabric Composer hosts. Monitor system logs for unusual commands or processes, especially those involving privileged user access. Verify if the system is running the vulnerable version of HPE Networking Fabric Composer.

Impact Analysis

An attacker could gain complete control over the HPE Networking Fabric Composer host, allowing them to execute malicious commands with high privileges. This could lead to data theft, system disruption, or further network infiltration depending on the host's role in the environment.

Compliance Impact

This vulnerability could lead to complete compromise of the HPE Networking Fabric Composer host, potentially exposing sensitive data or systems. Such a compromise may violate compliance requirements under GDPR or HIPAA if it involves unauthorized access to personal or health information.

Mitigation Strategies

Apply vendor-provided patches or updates for HPE Networking Fabric Composer immediately. Isolate affected systems from untrusted networks. Monitor for unusual activity or unauthorized access. Restrict network access to the system using firewalls or access controls.
