CVE-2025-38739
Dell · Dell Digital Delivery
A high-severity vulnerability has been identified in the Dell Digital Delivery software, which is pre-installed on numerous Dell computer models.
Executive summary
A high-severity vulnerability has been identified in the Dell Digital Delivery software, which is pre-installed on numerous Dell computer models. An attacker with local access to a vulnerable system could exploit this flaw to gain elevated administrative privileges. Successful exploitation would allow an attacker to take full control of the affected workstation, install malicious software, steal sensitive data, and potentially move to other systems on the network.
Vulnerability
The vulnerability is a local privilege escalation (LPE) flaw within the Dell Digital Delivery service. The service, which runs with SYSTEM-level privileges, improperly handles file operations or executable paths, creating a condition where a low-privileged local user can manipulate the service's behavior. An attacker could exploit this by placing a malicious payload in a specific, insecurely permissioned directory, which the Dell Digital Delivery service would then execute with full system privileges, effectively escalating the attacker's access from a standard user to a system administrator.
Business impact
This vulnerability is rated as High severity with a CVSS score of 7.2. The primary business impact is the complete compromise of endpoint integrity and confidentiality. An attacker successfully exploiting this flaw on a corporate workstation could bypass all standard user access controls to access or exfiltrate sensitive business data, intellectual property, or personal identifiable information (PII). Furthermore, the compromised machine could be used as a staging point to launch further attacks within the corporate network, install ransomware, or deploy persistent backdoors for long-term espionage.
Remediation
Immediate Action: The primary remediation is to apply the security update provided by the vendor immediately. System administrators should ensure that all instances of Dell Digital Delivery are updated to version 5.0 or later. Following the update, security teams should monitor for any signs of post-patch exploitation attempts and review system and application access logs for anomalous activity preceding the patch deployment.
Proactive Monitoring: Security teams should configure monitoring tools to look for signs of exploitation. This includes monitoring for unexpected processes being spawned by the Dell Digital Delivery service (e.g., DellDigitalDelivery.exe or a related service process). Watch for suspicious file writes to system directories or modifications to registry keys by processes running under a standard user context. Endpoint Detection and Response (EDR) solutions should be tuned to alert on processes that gain SYSTEM-level privileges unexpectedly.
Compensating Controls: If patching cannot be immediately deployed, consider the following controls:
- Application Control: Use application whitelisting solutions like AppLocker or Windows Defender Application Control to prevent unauthorized executables from running.
- Uninstall Software: If Dell Digital Delivery is not a business-critical application in your environment, consider uninstalling it as a temporary or permanent mitigating control.
- Endpoint Hardening: Ensure EDR/XDR solutions are deployed and active on all endpoints to detect and block malicious behaviors associated with privilege escalation.
Exploitation status
Public Exploit Available: false
Analyst recommendation
Given the high CVSS score and the widespread deployment of Dell hardware in corporate environments, this vulnerability presents a significant risk. We recommend that organizations prioritize the immediate patching of CVE-2025-38739 across all managed Dell endpoints. This vulnerability should be considered a critical link in a potential attack chain, allowing an intruder to escalate a minor breach into a full system compromise. Although not currently on the CISA KEV list, its high impact warrants urgent attention from patch management and security operations teams.
