CVE-2025-38738 is a vulnerability identified in Dell's SupportAssist for Home PCs Installer executable, specifically in versions 4.8.2.29006 and prior. The vulnerability is classified under CWE-266, which pertains to Incorrect Privilege Assignment. This means that the installer improperly assigns privileges during its execution, allowing a low-privileged local attacker to potentially escalate their privileges on the affected system. The vulnerability requires local access and some user interaction to exploit, as indicated by the CVSS vector (AV:L/AC:H/PR:L/UI:R). The CVSS score of 6.7 categorizes this as a medium severity issue. The impact of successful exploitation includes full compromise of confidentiality, integrity, and availability of the system, as the attacker can gain elevated privileges, potentially leading to unauthorized access to sensitive data, installation of persistent malware, or disruption of system operations. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability affects the installer component of SupportAssist, a Dell utility designed to assist users with system maintenance and support tasks on home PCs. Given the nature of the vulnerability, exploitation would require the attacker to have local access and to interact with the system, but once exploited, it could allow significant control escalation beyond the initial user privileges.

For European organizations, the impact of this vulnerability depends largely on the prevalence of Dell home PCs running SupportAssist within their environment, particularly in remote work or home office setups. If employees use vulnerable versions of SupportAssist on their home machines connected to corporate networks, attackers could leverage this vulnerability to gain elevated privileges on those devices. This could lead to lateral movement into corporate networks, data exfiltration, or disruption of business operations. The compromise of confidentiality, integrity, and availability poses risks to sensitive corporate data and continuity. Additionally, the vulnerability could be exploited by malicious insiders or attackers who gain physical or remote access to a user's machine with limited privileges. Although the vulnerability requires local access and user interaction, the widespread use of Dell home PCs in Europe means that the attack surface is non-negligible. The lack of known exploits in the wild currently reduces immediate risk, but the medium severity rating and potential impact warrant proactive mitigation.

European organizations should implement a multi-layered mitigation strategy: 1) Inventory and identify all Dell home PCs running SupportAssist, focusing on versions 4.8.2.29006 and earlier. 2) Monitor Dell's official channels for patches or updates addressing CVE-2025-38738 and prioritize prompt deployment once available. 3) Until patches are released, restrict local user permissions to the minimum necessary and enforce strict user account control policies to limit privilege escalation opportunities. 4) Educate users about the risks of running untrusted installers and the importance of not interacting with suspicious prompts or software. 5) Employ endpoint detection and response (EDR) solutions capable of detecting unusual privilege escalation attempts or installer behaviors. 6) For remote or home users, enforce VPN and network segmentation to limit access from potentially compromised home devices to sensitive corporate resources. 7) Regularly audit installed software versions and configurations on home PCs used for work purposes to ensure compliance with security policies.
