CVE-2022-34363 Overview
CVE-2022-34363 is an authorization bypass vulnerability in Dell Unisphere for PowerMax vApp versions prior to 10.0.0.2. The flaw resides in the Unisphere for VMAX application running within the vApp deployment. An authenticated attacker with low privileges can exploit this issue over the network to perform actions beyond their authorized scope. The weakness is categorized as Improper Authorization [CWE-285] and affects the integrity of managed storage resources.
Critical Impact
An authenticated low-privileged attacker can bypass authorization checks in Unisphere for VMAX and modify storage management data without proper permissions.
Affected Products
- Dell Unisphere for PowerMax vApp versions prior to 10.0.0.2
- Unisphere for VMAX application running in the vApp
- Dell PowerMax storage management deployments using the affected vApp

Technical Details for CVE-2022-34363
Vulnerability Analysis
The vulnerability stems from improper authorization enforcement in the Unisphere for VMAX application bundled within the PowerMax vApp. Dell Unisphere for PowerMax is the web-based management interface used to administer Dell PowerMax and VMAX storage arrays. The vApp packaging delivers Unisphere as a virtual appliance for VMware environments.
The flaw allows an authenticated user with low privileges to perform operations that should require higher authorization. Because the attack vector is network-based and requires no user interaction, an attacker holding any valid account on the management interface can issue requests that bypass intended access controls. The impact is limited to integrity, meaning the attacker can modify configuration or data without affecting confidentiality or availability directly.
Root Cause
The root cause is missing or insufficient authorization checks within specific Unisphere for VMAX request handlers. The application validates that the requester is authenticated but does not consistently verify whether the authenticated principal has permission to invoke the requested operation. This represents a classic broken access control pattern aligned with [CWE-285].
Attack Vector
Exploitation requires network reachability to the Unisphere management interface and valid low-privileged credentials. The attacker submits crafted requests to functionality that should be restricted to administrators. No specialized tooling is required because the requests use the standard Unisphere management API. See the Dell Services Knowledge Article for vendor technical details.
Detection Methods for CVE-2022-34363
Indicators of Compromise
- Unisphere for PowerMax vApp instances running versions earlier than 10.0.0.2
- Audit log entries showing low-privileged accounts invoking administrative operations
- Unexpected storage configuration changes initiated by non-administrative users
Detection Strategies
- Review Unisphere audit logs for privilege mismatches between the authenticated user role and the operation performed
- Compare expected role-based access patterns against actual API call activity captured by the management interface
- Correlate authentication events with subsequent administrative actions to identify authorization anomalies
Monitoring Recommendations
- Forward Unisphere for PowerMax audit and access logs to a centralized logging platform for retention and correlation
- Alert on configuration changes performed by accounts that lack administrative role assignments
- Monitor network access to the Unisphere management interface and restrict it to authorized administrative networks
How to Mitigate CVE-2022-34363
Immediate Actions Required
- Upgrade Dell Unisphere for PowerMax vApp to version 10.0.0.2 or later
- Inventory all Unisphere for PowerMax vApp deployments and identify instances running affected versions
- Audit account privileges and remove unnecessary access to the Unisphere management interface
- Review historical audit logs for evidence of unauthorized actions performed by low-privileged accounts
Patch Information
Dell has released a fixed version in Unisphere for PowerMax vApp 10.0.0.2. Customers should consult the Dell Services Knowledge Article for the official remediation guidance and download instructions.
Workarounds
- Restrict network access to the Unisphere management interface using firewall rules or network segmentation
- Limit Unisphere user accounts to the minimum required and disable unused low-privileged accounts
- Enforce strong authentication and rotate credentials for all Unisphere users until patching is complete
