CVE-2023-4343 identifies a security vulnerability in the Broadcom LSI Storage Authority (LSA) RAID controller's web management interface. The core issue is that sensitive password information is included directly in the URL as a search parameter during authentication or configuration operations. URLs are often logged by web servers, proxies, and client browsers, and can be exposed in browser history or network traffic captures. This exposure increases the risk of credential leakage without requiring active exploitation or complex attack vectors. An attacker with access to network traffic or logs could retrieve these passwords and gain unauthorized access to the RAID controller's management interface. This could lead to unauthorized configuration changes, data access, or disruption of storage services. The vulnerability does not currently have a CVSS score or known exploits in the wild, but the nature of the flaw suggests a significant confidentiality risk. The affected product, Broadcom LSI Storage Authority, is commonly deployed in enterprise storage solutions, making this vulnerability relevant to organizations managing critical data infrastructure. The lack of authentication bypass or remote code execution reduces the immediate risk, but the exposure of credentials is a serious concern that can facilitate further attacks.

For European organizations, the exposure of administrative credentials in URLs can lead to unauthorized access to critical storage infrastructure. This can compromise the confidentiality and integrity of stored data, potentially leading to data breaches or manipulation of storage configurations. Enterprises in sectors such as finance, healthcare, telecommunications, and government, which rely heavily on Broadcom RAID controllers for data storage, are at heightened risk. The vulnerability could also facilitate lateral movement within networks if attackers leverage stolen credentials to access other systems. Additionally, exposure of passwords in URLs can undermine compliance with data protection regulations such as GDPR, leading to legal and reputational consequences. The impact is amplified in environments where network monitoring or logging is extensive, as these increase the likelihood of credential exposure. Although no active exploitation is reported, the vulnerability presents a clear vector for attackers to gain privileged access if not mitigated promptly.

Organizations should immediately audit their use of the Broadcom LSI Storage Authority web interface to identify if password information is exposed in URLs. Network administrators should restrict access to the RAID controller management interface using network segmentation, VPNs, or IP whitelisting to limit exposure. It is critical to avoid sharing URLs containing sensitive parameters and to clear browser histories and logs that may contain such URLs. Monitoring network traffic for suspicious access patterns to the LSA interface can help detect potential exploitation attempts. Organizations should engage with Broadcom to obtain patches or updates addressing this vulnerability and apply them as soon as they become available. In the interim, consider disabling web interface access if possible or enforcing multi-factor authentication to reduce the risk of unauthorized access. Additionally, review logging configurations to ensure sensitive information is not recorded in logs or monitoring tools. Educate administrators on secure credential handling practices to prevent accidental exposure.
