CVE-2025-38742 identifies an Incorrect Permission Assignment vulnerability (CWE-732) in Dell's iDRAC Service Module (iSM) versions prior to 6.0.3.0. The iSM is a component that facilitates management and monitoring of Dell servers via the Integrated Dell Remote Access Controller (iDRAC). The vulnerability arises because critical resources within the iSM are assigned permissions that are too permissive, allowing a low privileged local attacker to gain unauthorized access. Exploitation requires local access to the system but does not require user interaction or elevated privileges initially. Once exploited, the attacker can execute arbitrary code, potentially compromising confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score is 5.3, with vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L, indicating local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, and low impact on confidentiality, integrity, and availability. No public exploits or patches are currently available, but the vulnerability is published and recognized by Dell. This flaw could be leveraged in environments where local access is possible, such as through compromised user accounts or insider threats. The vulnerability underscores the importance of strict permission management on critical system components in server management modules.

The vulnerability allows a low privileged local attacker to execute arbitrary code on Dell servers managed via iDRAC Service Module, potentially leading to unauthorized access to sensitive data, modification of system configurations, or disruption of server operations. This can undermine the confidentiality, integrity, and availability of critical infrastructure managed by affected Dell servers. Organizations relying on iDRAC for remote management in data centers, cloud environments, and enterprise IT infrastructures could face operational disruptions or data breaches if exploited. Although remote exploitation is not possible, insider threats or attackers who gain local access through other means could leverage this vulnerability to escalate privileges or maintain persistence. The medium severity rating reflects the balance between the requirement for local access and the significant impact of code execution. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially in high-security environments.

Organizations should immediately upgrade the Dell iDRAC Service Module to version 6.0.3.0 or later once available to remediate the incorrect permission assignment. Until patches are released, restrict local access to systems running vulnerable versions by enforcing strict access controls and monitoring local user activities. Implement robust endpoint security solutions to detect and prevent unauthorized local privilege escalation attempts. Regularly audit permissions on critical resources within server management modules to ensure they adhere to the principle of least privilege. Employ network segmentation to isolate management interfaces like iDRAC from general user networks, minimizing the risk of local access by unauthorized users. Additionally, enforce strong authentication and logging on management interfaces to detect suspicious activities. Organizations should also maintain up-to-date inventories of affected systems and apply compensating controls such as host-based intrusion detection systems (HIDS) to monitor for exploitation attempts.
