Dell Command Update (DCU), versions prior to 5.7.1, contain an Incorrect Authorization vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges.
AnalysisAI
Elevation of privilege in Dell Command Update (DCU) versions prior to 5.7.1 allows a local low-privileged attacker to gain elevated permissions through an Incorrect Authorization flaw (CWE-863). The vulnerability does not require user interaction or special configuration beyond the presence of a low-privileged local account on a Dell system running a vulnerable DCU version. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing low-privileged local account on the target Windows system with Dell Command Update installed in a version prior to 5.7.1 (confirmed by CVSS AV:L/PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.5 (Medium) with vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N accurately captures the constrained threat model: exploitation is bounded to local authenticated access with low privileges, no user interaction, and no network exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a standard local user account on a Dell system running DCU prior to 5.7.1 - whether an insider, a compromised workstation session, or an attacker who has achieved initial access via phishing - invokes a DCU interface or internal operation that is protected by a flawed authorization check. Because the authorization logic reaches an incorrect decision (CWE-863), the operation executes with elevated privileges, granting the attacker administrative control over the local system. … |
| Remediation | Upgrade Dell Command Update to version 5.7.1 or later, which resolves this vulnerability per Dell 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. |
