CVE-2026-27101 is a security vulnerability identified in Dell Secure Connect Gateway (SCG) versions 5.28.00.xx through 5.32.00.xx. The flaw is categorized as CWE-22, which involves improper limitation of a pathname to a restricted directory, commonly known as a path traversal vulnerability. This vulnerability allows an attacker with high privileges on the management network to craft malicious pathnames that bypass intended directory restrictions. By exploiting this, the attacker can access or manipulate files outside the designated directories, potentially leading to remote code execution on the SCG appliance or application. The vulnerability does not require user interaction but does require the attacker to have high-level privileges and network access to the management interface, limiting the attack surface to internal or trusted network segments. The CVSS v3.1 base score is 4.7, reflecting a medium severity level due to the requirement for high privileges and the limited scope of impact on confidentiality, integrity, and availability. No public exploits or active exploitation have been reported to date. The vulnerability highlights the importance of proper input validation and pathname sanitization in security gateway products that manage critical network access.

If exploited, this vulnerability could allow a high-privileged attacker within the management network to execute arbitrary code remotely on the Dell Secure Connect Gateway appliance or application. This could lead to unauthorized access to sensitive configuration files, modification of system settings, or disruption of secure connectivity services. The impact on confidentiality includes potential exposure of sensitive network credentials or configurations. Integrity could be compromised by unauthorized changes to system files or security policies. Availability might be affected if the attacker disrupts gateway operations or causes system instability. However, the requirement for high privileges and network access limits the risk to internal threat actors or compromised administrators. Organizations relying on Dell SCG for secure network access could face increased risk of lateral movement or persistent footholds within their infrastructure if this vulnerability is exploited.

To mitigate this vulnerability, organizations should implement strict access controls on the management network to ensure only trusted, high-privileged administrators can access the Dell Secure Connect Gateway interfaces. Network segmentation and firewall rules should restrict management access to known IP addresses and secure channels. Monitor and audit management network activity for suspicious behavior indicative of exploitation attempts. Dell should be engaged to provide patches or updates addressing this vulnerability; organizations must apply these patches promptly once available. Additionally, administrators should review and harden configuration settings on the SCG appliance to minimize exposure. Employing intrusion detection systems that can identify anomalous file access or path traversal attempts may provide early warning. Finally, conduct regular security assessments and penetration tests focusing on management interfaces to detect similar vulnerabilities proactively.
