Broadcom RAID Controller Insecure HTTP Configuration Vulnerability.

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2023-4338

The vulnerability affects a RAID controller web interface. While web interfaces can be exposed, RAID management interfaces are typically intended for internal administrative use within a local network or management segment, and exposure of such devices directly to the public internet is considered an uncommon or improper deployment configuration.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in the web interface of Broadcom RAID controllers. The issue stems from an insecure default HTTP configuration that lacks essential security headers, potentially allowing unauthorized access and control over storage systems. The primary concern is to confirm if this technology is in use and if it is exposed in a manner that could be exploited.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by accessing the Broadcom RAID Controller's web interface. If the interface is exposed and uses insecure default HTTP configurations without proper content type protection, an attacker might be able to manipulate how the web server handles content, potentially leading to serious security consequences. This could allow an attacker to compromise the confidentiality, integrity, and availability of the system.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to execute arbitrary code on the affected RAID controller. This is possible when the web interface is accessible over a network and insecure HTTP configurations are present. The impact could range from data corruption to full system compromise.

Data/System Asset: RAID controller management data.
Exposure: Network access to web interface.
Consequence: Arbitrary code execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

Infrastructure and security teams are likely responsible for addressing this vulnerability in Broadcom RAID controller web interfaces. The first practical step is to identify all instances of this interface, determine their reachability and business criticality, and then assign ownership for remediation planning.

Frequently asked questions

What is the Broadcom RAID Controller web interface?

This software provides a browser-based management console for hardware RAID controllers. It is used by administrators to configure storage arrays, monitor drive health, and manage data redundancy settings on servers, acting as a critical bridge between the user and the physical storage hardware.

Why is this CVE-2023-4338 a security concern?

The issue is classified as a missing security header vulnerability. Specifically, the web interface fails to implement the X-Content-Type-Options header. This weakness can cause the browser to misinterpret content types, potentially allowing an attacker to manipulate system data or gain unauthorized control over the RAID controller's functions.

How can an attacker trigger this vulnerability?

An attacker needs network access to the controller's management web interface. The vulnerability relies on the software's default insecure HTTP configuration. Importantly, this issue is not triggered if the interface is completely isolated from the network or if access is strictly governed by secure, restricted management segments.

Is my Broadcom RAID controller at risk?

Risk depends heavily on how the device is connected. Halo Surface Signal indicates that while these interfaces exist, they are designed for internal management. If your controller is directly reachable from the public internet, it faces a much higher risk than a device residing on a private, non-routed management network.

What should I do if I use this hardware?

Begin by auditing your infrastructure to locate all instances of the Broadcom RAID Controller web interface. Determine which devices are reachable from your network's perimeter versus those on restricted segments. Prioritize verifying access controls and coordinate with your infrastructure team to review security configurations for these interfaces.
