CVE-2026-26945 is a Process Control vulnerability (CWE-114) identified in Dell Integrated Dell Remote Access Controller (iDRAC) firmware versions prior to 7.00.00.181 for 9 and 14G, prior to 7.20.10.50 for 15G and 16G, and prior to 1.20.25.00 for 10 and 17G hardware. iDRAC is a specialized management controller embedded in Dell servers that provides out-of-band management capabilities, including remote monitoring, firmware updates, and system configuration. The vulnerability allows a high privileged attacker with adjacent network access—meaning the attacker must be on the same local network segment or have network proximity—to manipulate process control mechanisms within iDRAC. This manipulation can lead to arbitrary code execution, compromising the integrity of the management controller and potentially the host system. The CVSS v3.1 score is 5.3 (medium), reflecting the requirement for high privileges and high attack complexity, no user interaction, and limited confidentiality impact but high integrity impact. No public exploits or active exploitation have been reported to date. The vulnerability highlights the risks associated with privileged access to management interfaces and the importance of securing out-of-band management channels. Since iDRAC is widely used in enterprise and data center environments, exploitation could facilitate further lateral movement or persistent footholds within critical infrastructure.

The primary impact of CVE-2026-26945 is unauthorized code execution on the iDRAC management controller, which can undermine the integrity of server management operations. Successful exploitation could allow attackers to alter firmware settings, disable security controls, or install persistent malware, potentially leading to broader compromise of the server and connected infrastructure. This could disrupt availability indirectly by impairing management functions or cause data integrity issues through unauthorized configuration changes. Organizations relying on Dell servers with affected iDRAC versions, especially in data centers, cloud providers, and critical infrastructure sectors, face risks of targeted attacks that leverage this vulnerability for lateral movement or persistent access. The requirement for high privileges and adjacent network access limits the attack surface but does not eliminate risk, particularly in environments where network segmentation is weak or insider threats exist. The absence of known exploits reduces immediate risk but warrants proactive remediation to prevent future exploitation.

1. Apply firmware updates from Dell as soon as they become available for the affected iDRAC versions to remediate the vulnerability. 2. Restrict network access to iDRAC interfaces by implementing strict network segmentation and firewall rules, allowing only trusted management stations to connect. 3. Enforce strong authentication and access control policies for iDRAC, including multi-factor authentication where supported. 4. Monitor network traffic to and from iDRAC interfaces for anomalous activity indicative of exploitation attempts. 5. Disable or limit iDRAC features not in use to reduce the attack surface. 6. Regularly audit and review privileged user accounts and their access to management controllers. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect suspicious behavior targeting iDRAC. 8. Educate administrators about the risks of adjacent network access and the importance of securing management networks. These steps go beyond generic advice by focusing on network-level controls, access management, and proactive monitoring specific to iDRAC environments.
