CVE-2023-4341 identifies a privilege escalation vulnerability in Broadcom's LSI Storage Authority (LSA), a management software for Broadcom RAID controllers. The vulnerability stems from the Web GUI component creating insecure folders with improper permissions, which can be leveraged by an attacker to escalate privileges to root on the affected system. This escalation allows an attacker to gain full administrative control over the RAID controller management environment, potentially compromising the underlying storage infrastructure. The vulnerability affects all versions indicated as '0' in the data, suggesting it may be present in initial or unspecified versions of the software. No CVSS score has been assigned yet, and no known exploits are reported in the wild, indicating it may be newly discovered or not yet weaponized. The root cause relates to insecure folder creation, which could allow local or remote attackers with some level of access to the Web GUI to execute privilege escalation attacks. Given the critical role of RAID controllers in data storage and availability, exploitation could lead to unauthorized data access, data integrity violations, or denial of service through manipulation of storage configurations. The vulnerability was published on August 15, 2023, by the CVE database and assigned by certcc. The lack of patches or exploit details suggests organizations should proactively monitor and restrict access to the LSA Web GUI and prepare to apply vendor updates once available.

For European organizations, the impact of CVE-2023-4341 could be severe, especially for those relying on Broadcom RAID controllers in data centers, cloud infrastructure, and enterprise storage systems. Successful exploitation could lead to full root access on management systems, enabling attackers to manipulate RAID configurations, access sensitive stored data, or disrupt storage availability. This compromises confidentiality, integrity, and availability of critical data assets. Industries such as finance, healthcare, telecommunications, and government, which depend heavily on reliable and secure storage infrastructure, would be particularly vulnerable. The ability to escalate privileges without user interaction increases the risk of automated or stealthy attacks. Additionally, the lack of current public exploits means organizations may be unprepared, increasing the window of exposure. The threat could also affect managed service providers and cloud operators using Broadcom RAID solutions, potentially cascading impacts to their European clients.

Organizations should immediately audit and restrict access to the LSI Storage Authority Web GUI, ensuring it is only accessible to trusted administrators via secure networks or VPNs. Implement strict network segmentation and firewall rules to limit exposure of management interfaces. Monitor logs for unusual access patterns or privilege escalation attempts related to the LSA software. Since no official patches are currently available, maintain close communication with Broadcom for updates and apply patches promptly once released. Consider deploying host-based intrusion detection systems (HIDS) to detect unauthorized changes to folder permissions or suspicious activity on the RAID controller management hosts. Conduct regular security assessments and penetration tests focusing on storage management systems. Additionally, enforce strong authentication mechanisms and consider multi-factor authentication for access to the LSA Web GUI to reduce the risk of unauthorized exploitation.
