CVE-2025-45376 is a vulnerability classified under CWE-280 (Improper Handling of Insufficient Permissions or Privileges) affecting Dell Repository Manager (DRM) version 3.4.7. The flaw allows a low-privileged attacker with local access to exploit the application’s insufficient permission checks, leading to elevation of privileges. The vulnerability arises because DRM does not properly enforce permission boundaries, enabling unauthorized actions that should be restricted to higher-privileged users. The CVSS v3.1 score is 7.5 (high), with vector AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H, indicating local attack vector, high attack complexity, low privileges required, user interaction required, scope change, and high impacts on confidentiality, integrity, and availability. Although no public exploits are known yet, the vulnerability poses a significant risk due to the potential for attackers to gain elevated privileges and fully compromise affected systems. Dell Repository Manager is used primarily for managing firmware and driver updates on Dell hardware, making it a critical tool in enterprise environments. The vulnerability was published on September 29, 2025, and affects version 3.4.7; version 3.4.8 is also mentioned but not explicitly confirmed as vulnerable. No patches or mitigation links were provided at the time of publication.

The vulnerability enables a low-privileged local attacker to escalate privileges, potentially gaining administrative or SYSTEM-level access on affected machines. This can lead to full system compromise, including unauthorized access to sensitive data, modification or deletion of critical files, and disruption of system availability. Since Dell Repository Manager is widely used in enterprise environments for hardware management, exploitation could facilitate lateral movement within corporate networks, undermining overall security posture. The elevated privileges could also allow attackers to disable security controls, install persistent malware, or exfiltrate confidential information. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk in environments where attackers can gain initial footholds via phishing, physical access, or insider threats. The scope change in the CVSS vector indicates that the vulnerability affects resources beyond the initially vulnerable component, increasing the breadth of impact.

Organizations should immediately verify if Dell Repository Manager version 3.4.7 is deployed in their environment and prioritize upgrading to a fixed version once available. In the absence of an official patch, apply strict access controls to limit local user permissions on systems running DRM, ensuring only trusted administrators have access. Employ application whitelisting and endpoint protection solutions to detect and block suspicious activities related to DRM processes. Monitor system logs for unusual privilege escalation attempts or unauthorized access patterns. Restrict physical and remote access to critical systems to reduce the risk of local exploitation. Conduct user awareness training to minimize risky user interactions that could trigger exploitation. Engage with Dell support channels for any interim mitigations or workarounds. Finally, implement network segmentation to contain potential compromises and reduce lateral movement opportunities.
