CVE-2023-4332 identifies a security vulnerability in Broadcom's LSI Storage Authority (LSA), specifically within the RAID controller's web interface. The issue is classified under CWE-732, which relates to incorrect permission assignment for critical resources. In this case, the vulnerability arises from improper permissions set on a log file used by the LSA application. Such misconfigurations can allow unauthorized users—potentially even unauthenticated attackers with network access—to read or manipulate log files that may contain sensitive operational details, configuration data, or error messages. This exposure could facilitate reconnaissance, privilege escalation, or other attack vectors. The vulnerability was published on August 15, 2023, but no CVSS score or patches have been released yet, and no known exploits have been reported in the wild. The affected product, Broadcom LSI Storage Authority, is widely used for managing RAID controllers in enterprise storage environments. Given the critical role of storage controllers in data integrity and availability, improper access to their logs can undermine system security and complicate incident response. The lack of authentication requirements for accessing the vulnerable resource increases the risk profile, although exploitation requires network access to the management interface or system hosting the logs. This vulnerability highlights the importance of secure default permissions and regular audits of file access controls in critical infrastructure software.

For European organizations, the impact of CVE-2023-4332 can be significant, especially for enterprises relying on Broadcom LSI Storage Authority for RAID management in data centers, cloud providers, and large-scale storage deployments. Unauthorized access to log files could reveal sensitive information about system configurations, error states, or operational procedures, which attackers could leverage to plan further attacks such as privilege escalation or lateral movement. Although the vulnerability does not directly allow code execution or data modification, the confidentiality breach can weaken overall security posture. In regulated sectors such as finance, healthcare, and government within Europe, exposure of such information could lead to compliance violations under GDPR or sector-specific regulations. The absence of known exploits reduces immediate risk, but the potential for future exploitation remains, especially if attackers develop tools to automate unauthorized access. Additionally, the vulnerability could complicate forensic investigations by allowing attackers to tamper with logs if write permissions are also misconfigured. Availability and integrity of storage systems could be indirectly affected if attackers use information gleaned from logs to disrupt RAID configurations or data access.

Since no official patches are currently available for CVE-2023-4332, European organizations should implement immediate compensating controls. First, conduct a thorough audit of file permissions on all systems running Broadcom LSI Storage Authority, focusing on log files and other critical resources. Restrict access to these files strictly to authorized administrative users and system processes. Disable or limit network access to the RAID controller web interface to trusted management networks only, using network segmentation and firewall rules. Implement strong authentication and access controls on the management interface to prevent unauthorized access. Monitor access logs and system events for unusual activity related to the LSA application. If possible, temporarily disable or restrict logging features that expose sensitive information until a patch is released. Engage with Broadcom support channels to obtain updates on patch availability and recommended configurations. Finally, incorporate this vulnerability into vulnerability management and incident response plans to ensure rapid detection and remediation once exploits emerge.
