Dell Command Update (DCU), versions prior to 5.7.1, contain an Improper Restriction of XML External Entity Reference vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges and Server-side request forgery.
AnalysisAI
XML External Entity injection in Dell Command Update (DCU) versions prior to 5.7.1 enables a local attacker with low-privilege access to perform server-side request forgery and escalate privileges. The vulnerability stems from insufficient restriction of XML external entity references during DCU's XML parsing operations. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local system access with at minimum low-privilege credentials (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 score reflects a local, low-complexity attack requiring only low privileges with no user interaction, producing a scope change and high confidentiality impact - a meaningful combination. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A locally authenticated low-privilege user - such as a standard domain account on a managed Dell workstation - crafts a malicious XML file containing an XXE payload referencing an internal network resource or sensitive local file path. When DCU parses this XML during a normal update workflow, the external entity is resolved, causing DCU to issue an SSRF request to an attacker-controlled or internal target, or exposing file contents that can be leveraged to escalate privileges on the host. … |
| Remediation | Upgrade Dell Command Update to version 5.7.1 or later, as specified in Dell Security Advisory DSA-2026-309 available at https://www.dell.com/support/kbdoc/en-us/000501378/dsa-2026-309-security-update-for-dell-command-update-for-multiple-vulnerabilities. … Detailed patch versions, workarounds, and compensating controls in full report. |
