CVE-2025-27689 is an improper access control vulnerability classified under CWE-284 affecting Dell iDRAC Tools versions prior to 11.3.0.0. The Integrated Dell Remote Access Controller (iDRAC) is a widely used out-of-band management platform embedded in Dell servers, enabling administrators to remotely manage and monitor hardware. The vulnerability allows a low-privileged attacker with local access to escalate their privileges, potentially gaining administrative control over the system. The flaw arises from inadequate enforcement of access control policies within the iDRAC software, permitting unauthorized operations that should be restricted. The CVSS v3.1 base score of 7.8 reflects high severity, with attack vector local (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits have been reported in the wild yet, the vulnerability poses a serious risk because iDRAC is critical for server management and often trusted with elevated privileges. Exploitation could allow attackers to manipulate server configurations, access sensitive data, or disrupt operations. The vulnerability affects all Dell iDRAC Tools versions before 11.3.0.0, but specific affected versions are not enumerated. The issue was reserved in March 2025 and published in June 2025. No official patches or mitigation links are currently provided, indicating that organizations must monitor Dell advisories closely. The vulnerability underscores the need for strict local access controls and timely patch management in environments using iDRAC for server administration.

The impact of CVE-2025-27689 is significant for organizations relying on Dell iDRAC for server management. Successful exploitation allows a low-privileged local attacker to escalate privileges to administrative levels, potentially gaining full control over the server hardware and management functions. This can lead to unauthorized disclosure of sensitive information, unauthorized modification or deletion of data, and disruption or denial of service of critical infrastructure. Since iDRAC is used for out-of-band management, attackers could bypass network-level protections and directly manipulate hardware settings, firmware, or system configurations. This could facilitate persistent backdoors, sabotage, or lateral movement within data centers. The vulnerability is particularly impactful in environments with shared physical access, such as colocation facilities, managed service providers, or large enterprise data centers. The lack of user interaction required and low complexity of attack increase the likelihood of exploitation once local access is obtained. Although no exploits are known in the wild yet, the potential for damage is high, especially in sectors like finance, government, healthcare, and cloud service providers where Dell servers are prevalent.

To mitigate CVE-2025-27689, organizations should implement the following specific measures: 1) Restrict physical and local access to servers running Dell iDRAC Tools to trusted personnel only, using strict access control policies and monitoring. 2) Employ strong authentication and authorization mechanisms for local and remote management interfaces to reduce the risk of unauthorized access. 3) Monitor system logs and iDRAC audit trails for unusual privilege escalation attempts or suspicious activity indicative of exploitation attempts. 4) Segment management networks and isolate iDRAC interfaces from general user networks to limit exposure. 5) Apply the official Dell patch or update to iDRAC Tools version 11.3.0.0 or later as soon as it becomes available. 6) If patches are not yet available, consider temporary workarounds such as disabling unnecessary local management features or using host-based controls to restrict execution of iDRAC tools by low-privileged users. 7) Conduct regular security assessments and penetration testing focused on management interfaces to identify and remediate access control weaknesses. 8) Educate data center and IT staff about the risks of local privilege escalation vulnerabilities and enforce strict operational security practices.
