CVE-2024-49561 is an Incorrect Privilege Assignment vulnerability (CWE-266) affecting Dell SmartFabric OS10 Software versions 10.5.4.x, 10.5.5.x, 10.5.6.x, and 10.6.0.x. The flaw allows a low-privileged attacker who has local access to the system to escalate their privileges, potentially gaining administrative or root-level control. This vulnerability arises from improper configuration or enforcement of privilege levels within the OS10 software, enabling unauthorized access to sensitive functions or data. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction required. The attacker must have local access, which typically means physical access or access via a compromised internal network segment. No public exploits have been reported yet, but the vulnerability poses a significant risk in environments where Dell SmartFabric OS10 is used to manage network fabrics in data centers and enterprise networks. The vulnerability could allow attackers to manipulate network configurations, intercept or alter data flows, or disrupt network availability.

The vulnerability could lead to severe consequences for organizations relying on Dell SmartFabric OS10 for network fabric management. An attacker exploiting this flaw could gain elevated privileges, enabling them to modify network configurations, disable security controls, or access sensitive network traffic. This could result in data breaches, network downtime, or lateral movement within the network to compromise additional systems. The impact spans confidentiality, integrity, and availability, potentially affecting critical infrastructure and enterprise operations. Given the role of SmartFabric OS10 in data center and cloud environments, exploitation could disrupt business continuity and cause significant financial and reputational damage. The requirement for local access limits remote exploitation but does not eliminate risk, especially in environments with inadequate internal access controls or insider threats.

Organizations should implement strict local access controls to limit who can physically or logically access devices running Dell SmartFabric OS10. Network segmentation and zero-trust principles should be enforced to reduce the risk of an attacker gaining local access. Monitoring and alerting for unusual privilege escalations or configuration changes on SmartFabric OS10 devices should be established. Until patches are released by Dell, consider disabling or restricting non-essential local administrative interfaces and services. Regularly audit user accounts and permissions on affected devices to ensure least privilege principles are followed. Once Dell releases patches or updates addressing this vulnerability, prioritize immediate deployment in all affected environments. Additionally, maintain robust incident response plans to quickly identify and remediate any exploitation attempts.
