Beware of Man-in-the-Middle Attacks on your Dell Unity Storage System

CVSScvssV3_1: 8.6

Dell Unity storage systems are commonly used by organizations to consolidate storage and simplify data management. However, it is important for Dell Unity users to be aware of a critical vulnerability that could allow attackers to intercept and manipulate traffic between Dell Unity and vCenter servers.

The vulnerability, tracked as CVE-2023-43082, exists in the vmadapter component and could enable man-in-the-middle attacks. By obtaining a certificate signed by a trusted certificate authority, an attacker may be able to spoof the vCenter certificate authority and position themselves in the middle of communications. This would allow them to view and modify sensitive information like authentication details in transit.

In a man-in-the-middle attack, the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other. By spoofing trusted certificates, attackers could intercept login credentials and other sensitive data from Dell Unity storage systems.

If exploited, this has the potential to seriously compromise the security and integrity of storage resources, virtual infrastructure and company data.

The best way to protect against such attacks is to ensure Dell Unity systems are updated to the latest versions that have addressed this vulnerability. Administrators should also consider implementing certificate pinning or certificate revocation checks to prevent relying on certificates that may have been compromised. Vigilance around certificate management helps reduce the risk of man-in-the-middle attacks on Dell Unity storage.
