CVE-2023-4336 identifies a security vulnerability in the Broadcom LSI Storage Authority (LSA) RAID Controller's web interface, specifically related to its default HTTP configuration. The vulnerability arises because the web interface does not set the Secure attribute on cookies by default. The Secure attribute is critical for cookies as it instructs browsers to only send cookies over HTTPS connections, thereby protecting session cookies from being transmitted over unencrypted HTTP. Without this attribute, session cookies can be exposed to interception via man-in-the-middle (MITM) attacks on unencrypted networks. This exposure can lead to session hijacking, allowing attackers to impersonate legitimate users, potentially gaining unauthorized access to the RAID controller's management functions. The vulnerability affects all versions of LSI Storage Authority as no specific version restrictions are noted. No CVSS score has been assigned yet, and no known exploits have been reported in the wild, indicating this is a newly disclosed issue. The lack of the Secure attribute does not directly allow code execution or privilege escalation but compromises the confidentiality and integrity of session management. The vulnerability is particularly relevant for environments where the RAID controller's web interface is accessible over HTTP or untrusted networks. Since RAID controllers are critical infrastructure components managing storage arrays, unauthorized access could lead to data exposure or disruption of storage services. The absence of patches or official mitigation guidance suggests that organizations must implement compensating controls such as enforcing HTTPS and reviewing network access policies to protect the management interface.

For European organizations, the impact of CVE-2023-4336 centers on the potential compromise of RAID controller management sessions. If an attacker can intercept network traffic—especially in environments where the management interface is accessible over unencrypted HTTP—they could hijack administrative sessions. This could lead to unauthorized configuration changes, disruption of storage services, or exposure of sensitive data stored on RAID arrays. Organizations with remote or web-accessible management interfaces are at higher risk, including data centers, cloud providers, and enterprises with distributed infrastructure. The vulnerability undermines confidentiality and integrity but does not directly affect availability unless attackers deliberately disrupt storage configurations. Given the critical role of storage controllers in enterprise IT, any compromise could have cascading effects on business operations and data security. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often target misconfigured management interfaces. European organizations must consider the risk in the context of GDPR and other data protection regulations, as unauthorized access to storage systems could lead to data breaches with regulatory consequences.

To mitigate CVE-2023-4336, organizations should: 1) Immediately enforce HTTPS-only access to the Broadcom LSI Storage Authority web interface by configuring SSL/TLS certificates and disabling HTTP access to prevent cookie exposure over unencrypted channels. 2) Verify and configure the web server or application to set the Secure attribute on all session cookies to ensure they are only transmitted over secure connections. 3) Restrict network access to the RAID controller management interface using firewalls or network segmentation, limiting access to trusted administrative networks or VPNs. 4) Monitor network traffic and logs for unusual session activity or repeated login attempts that may indicate session hijacking attempts. 5) Stay alert for official patches or updates from Broadcom and apply them promptly once available. 6) Educate administrators about the risks of accessing management interfaces over insecure networks and encourage the use of secure remote access methods. 7) Conduct regular security assessments of management interfaces to detect misconfigurations or vulnerabilities. These steps go beyond generic advice by focusing on specific configuration changes and network controls tailored to the affected product and vulnerability nature.
