CVE-2025-27689 is a high-severity vulnerability affecting Dell iDRAC Tools versions prior to 11.3.0.0. The vulnerability is classified under CWE-284, indicating improper access control. Specifically, this flaw allows a low-privileged attacker with local access to the affected system to escalate their privileges. The Dell Integrated Dell Remote Access Controller (iDRAC) Tools are used for remote management of Dell servers, providing administrators with capabilities such as hardware monitoring, firmware updates, and system configuration. The vulnerability arises because the access control mechanisms within iDRAC Tools do not adequately restrict certain privileged operations, enabling an attacker who already has some level of local access to bypass restrictions and gain elevated privileges. According to the CVSS v3.1 vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), the attack requires local access (AV:L), has low attack complexity (AC:L), requires low privileges (PR:L), and no user interaction (UI:N). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning an attacker could fully compromise the system, access sensitive data, modify system configurations, or disrupt availability. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that this is a newly disclosed vulnerability. The lack of a patch means affected organizations must rely on mitigation and monitoring until an official fix is released. Given the critical role of iDRAC in server management, exploitation could allow attackers to gain control over server hardware management functions, potentially leading to full system compromise or persistent footholds in enterprise environments.

For European organizations, the impact of CVE-2025-27689 could be significant, especially for enterprises and data centers relying on Dell server infrastructure with iDRAC Tools deployed. Successful exploitation would allow attackers with local access—such as malicious insiders, compromised user accounts, or attackers who have gained limited footholds—to escalate privileges and gain full control over server management functions. This could lead to unauthorized access to sensitive data, manipulation of server configurations, disruption of critical services, and potential lateral movement within networks. Sectors such as finance, healthcare, telecommunications, and government agencies, which often use Dell servers for critical workloads, could face operational disruptions and data breaches. The vulnerability's requirement for local access limits remote exploitation but does not eliminate risk, as attackers often leverage initial access vectors such as phishing or exploiting other vulnerabilities to gain local presence. The high impact on confidentiality, integrity, and availability means that exploitation could severely affect business continuity and compliance with European data protection regulations like GDPR, potentially resulting in legal and financial consequences.

1. Restrict local access strictly: Limit physical and remote local access to servers running vulnerable iDRAC Tools to trusted personnel only. Implement strong access controls on consoles and management interfaces. 2. Monitor and audit local user activities: Enable detailed logging of local user actions on servers with iDRAC Tools and regularly review logs for suspicious privilege escalation attempts. 3. Employ network segmentation: Isolate management networks where iDRAC interfaces reside to reduce the risk of attackers gaining local access through lateral movement. 4. Use multi-factor authentication (MFA) for all administrative access, including local logins where possible, to reduce the risk of credential compromise. 5. Apply principle of least privilege: Ensure users and service accounts have only the minimum privileges necessary to perform their tasks, reducing the impact of any local compromise. 6. Prepare for patch deployment: Monitor Dell’s security advisories closely and plan for rapid deployment of the iDRAC Tools update to version 11.3.0.0 or later once available. 7. Employ endpoint detection and response (EDR) solutions: Use EDR tools to detect anomalous privilege escalation behaviors on servers. 8. Conduct internal penetration testing and vulnerability assessments focusing on local privilege escalation vectors to identify and remediate weaknesses proactively.
