CVE-2022-28165 in SANNav
Summary
by MITRE • 05/06/2022
A vulnerability in the role-based access control (RBAC) functionality of the Brocade SANNav before 2.2.0 could allow an authenticated, remote attacker to access resources that they should not be able to access and perform actions that they should not be able to perform. The vulnerability exists because restrictions are not performed on Server side to ensure the user has required permission before processing requests.

The vulnerability identified as CVE-2022-28165 represents a critical weakness in the role-based access control mechanisms of Brocade SANNav software versions prior to 2.2.0. This issue fundamentally undermines the security posture of storage network management systems by creating a path for authenticated remote attackers to bypass intended access controls. The vulnerability operates at the core of authorization enforcement where proper permission validation fails to occur on the server-side processing layer, allowing malicious actors to exploit this gap in the security architecture.
The technical flaw manifests as a failure in server-side input validation and permission checking within the RBAC framework. When users submit requests to the SANNav management interface, the system should verify that each operation aligns with the user's assigned roles and permissions before executing any actions. However, in affected versions, this validation process is incomplete or entirely absent, enabling attackers to manipulate requests and gain unauthorized access to resources they should not be able to reach. This represents a classic authorization bypass vulnerability that can be categorized under CWE-285, which deals with insufficient authorization in software systems. The flaw essentially allows privilege escalation through improper access control enforcement, where legitimate authenticated users can perform actions beyond their designated permissions.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass potential data compromise and system integrity violations within storage network environments. Attackers could potentially manipulate storage configurations, access sensitive network data, or perform administrative functions that should be restricted to specific privileged roles. This poses significant risks to enterprise storage infrastructures where SANNav is used for managing critical storage resources. The vulnerability affects the confidentiality, integrity, and availability of storage network management systems, making it particularly dangerous in environments where storage security is paramount. Organizations using affected versions face potential exposure to insider threats or external attacks that leverage this weakness to gain unauthorized control over their storage networks.
Mitigation strategies for CVE-2022-28165 center on immediate software updates to Brocade SANNav version 2.2.0 or later, which contains the necessary patches to address the server-side permission validation issues. System administrators should also implement network segmentation and monitoring to detect anomalous access patterns that might indicate exploitation attempts. Additional defensive measures include conducting comprehensive access control reviews, implementing least privilege principles for user accounts, and enabling detailed audit logging to track all administrative activities. From an ATT&CK framework perspective, this vulnerability aligns with techniques such as privilege escalation and defense evasion, as attackers can leverage it to expand their access within the storage network environment. Organizations should also consider implementing multi-factor authentication and regular security assessments to strengthen their overall security posture against similar authorization bypass threats. The vulnerability demonstrates the critical importance of server-side validation in maintaining secure access control systems, particularly in enterprise storage management platforms where unauthorized access can lead to significant operational and security consequences.
