The vulnerability identified in CVE-2018-7095 affects the 3PAR Service Processor (SP) firmware versions prior to SP-4.4.0.GA-110(MU7), representing a critical access control flaw that undermines the security posture of HPE 3PAR storage systems. This vulnerability resides within the service processor's authentication and authorization mechanisms, specifically targeting the access restriction controls that govern administrative access to the storage array's management interfaces. The flaw enables remote exploitation, meaning attackers can potentially bypass legitimate access controls without requiring physical presence or local network access, significantly expanding the attack surface and potential impact.
The technical nature of this vulnerability stems from insufficient validation of authentication tokens and session management within the service processor's web interface implementation. Attackers can exploit this weakness to gain unauthorized administrative access to the 3PAR storage array, effectively bypassing the normal access restriction mechanisms that should prevent unauthorized users from performing critical administrative functions. This flaw operates at the application layer of the OSI model, specifically targeting the web-based management interface that administrators use to configure and monitor the storage system. The vulnerability's remote exploitability means that an attacker positioned outside the network perimeter can potentially leverage this flaw, making it particularly dangerous for organizations with exposed management interfaces.
The operational impact of this vulnerability is severe and multifaceted, as it allows attackers to assume administrative privileges over the affected 3PAR storage arrays. Once exploited, adversaries can perform actions such as modifying storage configurations, creating or deleting volumes, accessing sensitive data stored on the array, and potentially disrupting storage services. The vulnerability also enables privilege escalation attacks that can lead to complete system compromise, as the service processor typically operates with elevated privileges. Organizations relying on 3PAR storage systems for critical data infrastructure face significant risk of data breaches, service disruptions, and potential regulatory compliance violations if this vulnerability remains unpatched. The impact extends beyond immediate security concerns to include potential financial losses, reputational damage, and operational downtime.
Organizations should immediately implement mitigations including applying the vendor-provided firmware update SP-4.4.0.GA-110(MU7) to address the vulnerability. Network segmentation and firewall rules should be implemented to restrict access to the service processor management interfaces, particularly limiting access to trusted administrative networks. Monitoring should be enhanced to detect unusual access patterns or authentication attempts to the affected systems. The vulnerability aligns with CWE-287, which addresses improper authentication issues, and maps to ATT&CK techniques such as T1078 for valid accounts and T1566 for phishing attacks that could lead to exploitation. Additionally, organizations should conduct comprehensive vulnerability assessments of their storage infrastructure and implement principle of least privilege access controls to minimize the potential impact of similar vulnerabilities in the future.
