CVE-2026-73598 Overview
CVE-2026-73598 affects Dell Secure Connect Gateway (SCG) Policy Manager in versions prior to 5.34.00.16. The vulnerability stems from an Incorrect Permission Assignment for Critical Resource [CWE-732]. A local attacker with low privileges can exploit the flaw to escalate privileges on the affected host. Dell disclosed the issue in security advisory DSA-2026-385 and released a fixed build. The vulnerability carries scope-change impact, meaning successful exploitation affects resources beyond the vulnerable component itself.
Critical Impact
A local, low-privileged attacker can gain elevated privileges on hosts running vulnerable Dell SCG Policy Manager builds, compromising the confidentiality, integrity, and availability of the system.

Technical Details for CVE-2026-73598
Vulnerability Analysis
CVE-2026-73598 is a privilege escalation vulnerability in Dell Secure Connect Gateway Policy Manager. The component assigns incorrect permissions to a critical resource, allowing a user with limited rights to interact with objects that should be restricted to higher-privileged accounts. Because the CVSS scope is changed, the impact extends beyond the Policy Manager process boundary and can affect other components on the host.
Successful exploitation grants the attacker elevated privileges. This enables further actions such as tampering with SCG configuration, reading sensitive credentials handled by the gateway, or pivoting to adjacent services that trust the elevated identity.
Root Cause
The root cause is an Incorrect Permission Assignment for Critical Resource, classified under [CWE-732]. A file, directory, registry key, service, or similar object shipped or created by SCG Policy Manager receives access controls that are too permissive. Standard local users can then modify or invoke that resource in a way that leads to code or actions running under a more privileged security context.
Attack Vector
Exploitation requires local access with low privileges and no user interaction. The attack complexity is high, indicating that the attacker must satisfy specific conditions on the target, such as timing, resource state, or configuration prerequisites. The vulnerability cannot be triggered remotely over the network.
Dell has not disclosed weaponized exploit details, and no public proof-of-concept is currently listed for CVE-2026-73598. Refer to the Dell Security Update DSA-2026-385 for vendor technical details.
Detection Methods for CVE-2026-73598
Indicators of Compromise
- Unexpected modifications to Dell SCG Policy Manager installation directories, binaries, or configuration files by non-administrative accounts.
- New or modified scheduled tasks, services, or startup entries referencing SCG Policy Manager paths.
- Local process execution where an SCG Policy Manager binary or service spawns child processes running under elevated accounts unexpectedly.
Detection Strategies
- Inventory SCG Policy Manager hosts and flag any installation with a version earlier than 5.34.00.16.
- Audit access control lists on SCG Policy Manager files, directories, and services for entries granting write or execute permissions to standard users or groups.
- Correlate local authentication events with subsequent privilege escalation events on hosts running SCG Policy Manager.
Monitoring Recommendations
- Enable file integrity monitoring on the SCG Policy Manager installation path and configuration store.
- Log and alert on service configuration changes and permission modifications targeting SCG components.
- Forward endpoint telemetry to a centralized analytics platform to identify privilege escalation patterns across the fleet.
How to Mitigate CVE-2026-73598
Immediate Actions Required
- Upgrade Dell Secure Connect Gateway Policy Manager to version 5.34.00.16 or later on all affected hosts.
- Restrict interactive and remote local logon rights on servers running SCG Policy Manager to trusted administrators only.
- Review and tighten filesystem and service permissions on SCG Policy Manager resources until patching completes.
Patch Information
Dell has released a fixed build in version 5.34.00.16. Full remediation details, affected build ranges, and download instructions are available in the Dell Security Update DSA-2026-385. Apply the vendor-supplied update as the primary remediation.
Workarounds
- Limit local access to SCG Policy Manager hosts to reduce the attacker pool able to reach the vulnerable component.
- Apply least-privilege principles to service accounts and remove unnecessary local user accounts from affected systems.
- Monitor SCG Policy Manager hosts for privilege escalation indicators until the patch is deployed.
