CVE-2026-79645 describes a Missing Authentication for Critical Function vulnerability in Dell Secure Connect Gateway 5.0 Application and Appliance. Versions prior to 5.36.00.00 (Application) and 5.36.00.16 (Appliance) do not properly enforce authentication on a critical function, enabling unauthenticated remote attackers to potentially access sensitive functions or data. The CVSS v3.1 base score is 8.2, reflecting network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, low confidentiality impact, high integrity impact, and no availability impact. No official remediation level or patch information is provided in the source data.

An unauthenticated remote attacker could exploit this vulnerability to gain unauthorized access to critical functions within the Dell SCG 5.0 Application or Appliance. This could lead to unauthorized modification of data or system integrity compromise. Confidentiality impact is low, integrity impact is high, and availability is not affected according to the CVSS vector. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official remediation level or patch information is provided, users should monitor Dell's security advisories for updates. Until a fix is available, restrict remote access to the affected systems and apply network-level controls to limit exposure.
