Broadcom RAID Controller Web GUI Privilege Escalation Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2023-4341

The vulnerability affects a RAID controller's Web GUI, which is a management interface. While such interfaces are ideally restricted to internal management networks, they are commonly deployed as web services accessible over the network. Given its role as a web-based administration tool, it is frequently exposed in environments where remote management or centralized monitoring is required.

Horizon Alert

Summary of the vulnerability and why it matters

A privilege escalation vulnerability exists in Broadcom RAID controller management software, allowing unauthorized users to gain root-level access by exploiting insecure folder creation within the Web GUI. This could potentially expose sensitive storage configurations and data.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by targeting the web interface of a Broadcom RAID controller. Since the web interface is accessible via the network and does not require initial authentication, an attacker can remotely interact with it. This interaction allows the creation of insecure folders, which can then lead to privilege escalation to root access on the affected system.

No authentication required for access.
Insecure folder creation via Web GUI.
Privilege escalation to root.

Live Threat

Operational Fix

Recommended remediation, mitigation, and detection steps

This critical privilege escalation vulnerability in Broadcom RAID controllers requires immediate attention from infrastructure and platform teams, potentially involving vendor management. The first practical step is to identify all instances of the affected RAID controller Web GUI, determine their network exposure and business criticality, and assign ownership to a specific team for assessment and remediation planning.

Frequently asked questions

What is the Broadcom RAID Controller Web Interface?

It is a management software component used to configure and monitor RAID storage systems. Administrators rely on this web-based interface to manage disk arrays, view controller status, and ensure data availability across storage hardware. It essentially acts as the control panel for the RAID controller's operations.

How does CVE-2023-4341 allow privilege escalation?

This vulnerability involves a weakness in how the software manages folder creation. Because the interface creates certain folders insecurely, an unauthorized user can manipulate these directory permissions to gain root-level access. By exploiting this flaw, an attacker effectively bypasses standard security controls to take full control of the underlying system.

Does this vulnerability require a specific trigger?

The flaw is triggered by interacting with the Web GUI to create these insecure folders. An attacker does not need prior authentication to initiate this process, as the interface accepts the commands remotely. It is important to note that this is a flaw in the interface's design; simply viewing the dashboard without performing these specific management actions does not inherently trigger the root access escalation.

Is my system at risk if it is not internet-facing?

According to Halo Surface Signal, this management interface is often deployed as a web service for remote administration. While internal networks are generally safer than the public internet, the risk remains if the interface is accessible to anyone on your internal network. If your management console is reachable over the network, it is potentially reachable by an attacker who has already breached your perimeter.

What should I do if I use this RAID software?

Start by identifying all instances of the Broadcom RAID Controller Web GUI within your environment. Once you have a complete inventory, assess which systems are reachable over the network and determine their business criticality. Coordinate with your infrastructure or platform teams to prioritize these systems for security review and plan for potential vendor-provided updates.
