CVE-2025-29984 is a vulnerability classified under CWE-284 (Improper Access Control) affecting Dell Trusted Device Client versions prior to 7.0.3.0. The root cause is incorrect default permissions set within the software, which allow a low privileged attacker with local access to escalate their privileges. This means an attacker who already has limited access to the system could exploit the vulnerability to gain higher-level privileges, potentially leading to full system compromise. The vulnerability requires local access and user interaction, which limits remote exploitation but does not eliminate risk in environments where multiple users share systems or where attackers can gain physical or remote desktop access. The CVSS 3.1 score of 6.7 reflects medium severity, with attack vector local (AV:L), attack complexity high (AC:H), privileges required low (PR:L), user interaction required (UI:R), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits are known at this time, but the vulnerability's presence in a trusted device client used for security purposes increases its potential impact. The lack of patch links suggests a patch may not yet be publicly available, emphasizing the need for interim mitigations. This vulnerability could be leveraged to bypass security controls, access sensitive data, or disrupt system operations.

The potential impact of CVE-2025-29984 is significant for organizations relying on Dell Trusted Device Client for device security and authentication. Successful exploitation could allow attackers with limited local access to escalate privileges, leading to unauthorized access to sensitive information, modification or deletion of critical data, and disruption of system availability. This could compromise the integrity of security policies enforced by the Dell Trusted Device Client, undermining trust in device authentication mechanisms. Organizations in sectors such as government, finance, healthcare, and critical infrastructure, where Dell products are widely used, may face increased risk of insider threats or lateral movement by attackers who have gained initial footholds. The requirement for local access and user interaction reduces the likelihood of widespread remote exploitation but does not eliminate risk in environments with shared or poorly controlled user access. The absence of known exploits currently limits immediate threat but also means organizations should proactively address the vulnerability before exploitation occurs.

To mitigate CVE-2025-29984, organizations should implement the following specific measures: 1) Restrict local user permissions rigorously to minimize the number of users with low privilege access on systems running Dell Trusted Device Client. 2) Enforce strict physical and logical access controls to prevent unauthorized local access. 3) Monitor system logs and security events for unusual privilege escalation attempts or suspicious activities related to Dell Trusted Device Client processes. 4) Apply principle of least privilege to all user accounts and services interacting with the affected software. 5) Once available, promptly deploy official patches or updates from Dell addressing this vulnerability. 6) Consider deploying application whitelisting or endpoint detection and response (EDR) solutions to detect and block exploitation attempts. 7) Educate users about the risks of local privilege escalation and the importance of not interacting with suspicious prompts or software. 8) Conduct regular security audits and vulnerability assessments focusing on local access controls and privilege management. These targeted actions go beyond generic advice by focusing on controlling local access vectors and monitoring for exploitation indicators specific to this vulnerability.
