Broadcom RAID Controller Web Interface Lacks HTTP Strict Transport Security Policy

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2023-4342

The vulnerability involves the RAID controller web interface. While this component is network-accessible, such management interfaces are typically intended for internal administrative use within a data center or local network, not for direct exposure to the public internet. While reachable in some environments, public internet exposure is uncommon for this type of hardware management tool.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory concerns a critical vulnerability in the Broadcom RAID controller web interface. The issue stems from a lack of proper security policy, which could allow for unauthorized access and manipulation of sensitive data if the interface is exposed. The primary concern is to confirm if this technology is in use and if it is accessible externally.

Insecure web interface on RAID controllers.
Confirms internal systems, not broad public risk.
Assess relevance and external exposure.

Attack Path

How an attacker could exploit the issue

An attacker could target the Broadcom RAID controller's web interface, which is exposed to the network and lacks a strict transport security policy. By exploiting this, an attacker could gain unauthorized access to sensitive information and potentially disrupt operations.

Network exposure without secure defaults.
Insecure web interface allows access.
High risk of data compromise and disruption.

Live Threat

Current exploitation, exposure, and threat context

The web interface of Broadcom RAID controllers could be exposed to risks when its default configurations lack HTTP strict-transport-security. This could allow an attacker to intercept sensitive administrative data or commands when users access the interface over an unencrypted connection.

Unencrypted network traffic.
Unauthorized system control.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Broadcom RAID Controller web interface's insecure defaults, specifically the lack of an HTTP Strict-Transport-Security policy, require immediate attention from infrastructure and security teams. The first practical step is to identify all instances of the affected RAID controller web interface, determine their network exposure, confirm business criticality, and assign ownership for remediation.

Infrastructure and Security teams should own.
Verify network exposure and business criticality.
Plan remediation based on identified risk.

Frequently asked questions

What is the Broadcom RAID Controller web interface?

This software component provides a browser-based management console for Broadcom RAID controllers. Administrators use this interface to configure storage arrays, monitor disk health, and manage data redundancy settings directly through the network.

Why does CVE-2023-4342 involve a lack of HSTS?

The vulnerability stems from missing HTTP Strict-Transport-Security (HSTS) headers. Without this policy, browsers may not enforce secure, encrypted HTTPS connections, potentially allowing traffic to be downgraded to unencrypted HTTP, which risks exposing administrative credentials or commands.

How can an attacker trigger this security weakness?

An attacker triggers this condition by intercepting network traffic between the user and the RAID controller. Note that simply browsing the interface locally does not trigger this bug; the risk arises when the connection is established over an unencrypted channel that lacks the mandated security policy.

Do I need to worry about this if my RAID controller is internal?

Halo Surface Signal indicates that while these interfaces are network-accessible, they are typically designed for internal management. Public internet exposure is uncommon for this hardware, but you should still assess whether your internal network configuration allows unauthorized segments to reach the interface.

What steps should I take if I use this software?

Begin by auditing your infrastructure to locate all instances of the affected Broadcom RAID controller web interface. Once identified, evaluate their current network accessibility, determine their criticality to your operations, and designate a team to manage the necessary configuration updates.
