DescriptionCVE.org

Dell Display and Peripheral Manager (DDPM Windows), versions prior to 2.3.0.17, contain an Authentication Bypass by Spoofing vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges and arbitrary code execution.

AnalysisAI

Authentication bypass via spoofing in Dell Display and Peripheral Manager (DDPM) for Windows, versions prior to 2.3.0.17, enables local low-privileged attackers to escalate their privileges and execute arbitrary code on affected systems. The flaw (CWE-290) allows an attacker already present on the system to spoof an authenticated identity, circumventing DDPM's internal access controls. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an attacker to have an interactive or remote local session on the target Windows host with at minimum a low-privileged (non-admin) account - confirmed by the CVSS PR:L metric. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 7.8 (High) is driven by full confidentiality, integrity, and availability impact (C:H/I:H/A:H) with a local, low-complexity attack vector requiring only low privileges and no user interaction (AV:L/AC:L/PR:L/UI:N/S:U). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary remediation is to upgrade Dell Display and Peripheral Manager for Windows to version 2.3.0.17 or later, as documented in Dell Security Advisory DSA-2026-320 (https://www.dell.com/support/kbdoc/en-us/000490038/dsa-2026-320-security-updates-for-dell-display-and-peripheral-manager-ddpm-windows-for-multiple-vulnerabilities). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit all Windows systems running DDPM to identify versions prior to 2.3.0.17 and quantify exposure. …
