Dell Command Update (DCU), versions prior to 5.7.1, contain an Exposure of Sensitive System Information to an Unauthorized Control Sphere vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Information disclosure.
AnalysisAI
Dell Command Update (DCU) versions prior to 5.7.1 expose sensitive system information to low-privileged local users, confirmed via Dell Security Advisory DSA-2026-309. The CVSS vector (AV:L/AC:L/PR:L/UI:N/C:H) indicates that a standard local account with no elevated rights and no user interaction is sufficient to trigger high-confidentiality-impact disclosure - potentially exposing hardware identifiers, system configuration details, or other privileged data handled by the update utility. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing local session on the target Windows system with at minimum a low-privileged (standard user) account - confirmed by CVSS AV:L/PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.5 (Medium) accurately reflects the constrained attack surface: AV:L limits exploitation to accounts with local system access, and PR:L requires at minimum a standard user session, ruling out anonymous or network-based attacks. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A standard Windows user account on a Dell machine running DCU prior to 5.7.1 interacts with the application - either directly through its interface or by querying accessible files, registry keys, or IPC mechanisms exposed by the utility - and retrieves sensitive system information beyond what that account should be permitted to access. No elevated privileges or network access are required. … |
| Remediation | Upgrade Dell Command Update to version 5.7.1 or later, which is the vendor-confirmed fix per Dell Security Advisory DSA-2026-309 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. |
