CVE-2025-36595 Overview
CVE-2025-36595 is a static code injection vulnerability affecting Dell Unisphere for PowerMax Virtual Appliance versions 9.2.4.x. The flaw is classified under CWE-96 as Improper Neutralization of Directives in Statically Saved Code. A remote attacker holding high privileges can inject directives into statically saved code, leading to arbitrary code execution on the affected appliance. Dell published the issue in advisory DSA-2025-235, which covers multiple vulnerabilities across the PowerMax product line.
Critical Impact
Successful exploitation grants code execution on the storage management appliance, compromising confidentiality, integrity, and availability of the PowerMax management plane.

Technical Details for CVE-2025-36595
Vulnerability Analysis
The vulnerability resides in how the Unisphere for PowerMax Virtual Appliance handles input that is persisted into statically saved code paths. Because attacker-controlled directives are not neutralized before being written into code that is later interpreted or executed, an authenticated high-privileged user can plant payloads that the appliance subsequently executes. The result is code execution in the context of the storage management appliance, which controls PowerMax array operations.
The attack requires network reachability to the management interface and valid high-privilege credentials. No user interaction is needed once the attacker has access, and exploitation does not require breaking out of an authenticated session.
Root Cause
The root cause is improper neutralization of code-relevant directives before they are persisted into a statically saved file or template ([CWE-96]). The appliance trusts the privileged user's input and writes it into a location that is later evaluated as code, removing the boundary between configuration data and executable logic.
Attack Vector
An authenticated administrator submits crafted input through a management interface that is stored on disk and later executed by an appliance subsystem. Because the storage layer treats the input as code rather than data, the injected directives run with the privileges of the executing process. See the Dell Security Update DSA-2025-235 for vendor-confirmed technical context. No public proof-of-concept is available at this time.
Detection Methods for CVE-2025-36595
Indicators of Compromise
- Unexpected modifications to scripts, templates, or configuration files used by the Unisphere for PowerMax appliance
- New or modified processes spawned by the management application outside of normal administrative workflows
- Outbound network connections initiated by the appliance to untrusted hosts following administrative activity
Detection Strategies
- Audit administrative actions on the Unisphere management interface and correlate them with file system writes to code or template directories
- Monitor process lineage on the virtual appliance to identify shell or interpreter processes spawned by the management service
- Compare file integrity baselines of the appliance against vendor-shipped images to detect injected directives
Monitoring Recommendations
- Forward appliance system and application logs to a centralized log platform for retention and correlation
- Alert on privileged authentication events to the Unisphere management interface from unexpected source addresses
- Review change-control records for any unscheduled administrator actions against PowerMax management components
How to Mitigate CVE-2025-36595
Immediate Actions Required
- Apply the fixed versions referenced in Dell DSA-2025-235 to all Unisphere for PowerMax Virtual Appliance 9.2.4.x deployments
- Rotate credentials for any administrator accounts on the affected appliances after patching
- Review audit logs for high-privileged activity preceding the patch window
Patch Information
Dell has issued a security update for the affected products under advisory DSA-2025-235. Administrators should consult the advisory for the exact remediated versions and upgrade procedures for Unisphere for PowerMax Virtual Appliance and Solutions Enabler Virtual Appliance.
Workarounds
- Restrict network access to the Unisphere management interface to a dedicated management network or jump host
- Enforce least privilege by limiting the number of accounts with high-privileged roles on the appliance
- Require multi-factor authentication for all administrative access to Dell storage management components
