Local access with low privileges suffices via IPC abuse; full C/I/A impact reflects achievable SYSTEM-level code execution; scope unchanged as compromise is contained to the local host.

Lifecycle Timeline
3DescriptionCVE.org
Dell Display and Peripheral Manager (DDPM Windows), versions prior to 2.3.0.17, contain Improper Access Control vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges and arbitrary code execution.
AnalysisAI
Local privilege escalation in Dell Display and Peripheral Manager (DDPM) for Windows enables a low-privileged local attacker to bypass access controls and execute arbitrary code at elevated privileges, affecting all versions prior to 2.3.0.17. The root cause is an improper access control flaw classified as CWE-290 (Authentication Bypass by Capture-replay), through which a standard user account can subvert DDPM's privileged service process and achieve system-level code execution. Dell has released version 2.3.0.17 via advisory DSA-2026-320, and no public exploit or active exploitation has been identified at time of analysis.
Technical ContextAI
Dell Display and Peripheral Manager (DDPM) is a Windows application for centrally managing Dell-branded displays and peripheral devices, identified by CPE cpe:2.3:a:dell:display_and_peripheral_manager_(ddpm_windows). The root cause is CWE-290 (Authentication Bypass by Capture-replay), a class of flaw in which an application's access control mechanism can be circumvented by replaying or spoofing an authentication artifact - such as a session token, IPC credential, or named pipe identity - without proper re-validation. This pattern is particularly common in device management software that runs a background service at SYSTEM or high-integrity level while exposing a local inter-process interface to lower-privileged user-space components. A low-privileged attacker can abuse this interface to impersonate or inject into the privileged service, bypassing the intended authorization boundary. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms the flaw is accessible to any local standard user account with no additional complexity, consistent with this IPC abuse pattern.
RemediationAI
The primary fix is to upgrade Dell Display and Peripheral Manager (DDPM) for Windows to version 2.3.0.17 or later, as documented in Dell Security Advisory DSA-2026-320 at 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. If immediate patching is not operationally feasible, administrators should restrict interactive or remote desktop access to affected endpoints to only trusted personnel, reducing the pool of potential low-privileged local attackers. Enforcing application control policies (e.g., Windows Defender Application Control or AppLocker) to prevent unauthorized processes from interacting with DDPM service interfaces provides an additional compensating control, though this requires policy tuning and may affect legitimate DDPM functionality. In environments that do not require display and peripheral management features, uninstalling DDPM entirely is a viable interim control, with the trade-off of losing centralized peripheral configuration management. Endpoint detection rules monitoring for unexpected child process creation or privilege changes originating from DDPM service processes can serve as a detective compensating measure.
