Description
Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to command execution.
Impact
Successful exploitation allows a low privileged local attacker to execute OS commands on the affected system, potentially leading to unauthorized access to sensitive information (high confidentiality impact). There is no reported impact on integrity or availability. No known exploits in the wild have been reported.
Summary
CVE-2026-78484 is an OS command injection vulnerability (CWE-77) affecting Dell Secure Connect Gateway 5.0 Application and Appliance. Versions prior to 5.36.00.00 (Application) and 5.36.00.16 (Appliance) are vulnerable. A low privileged attacker with local access could exploit this vulnerability to execute arbitrary OS commands. The CVSS v3.1 base score is 5.5, reflecting medium severity with high confidentiality impact but no integrity or availability impact. No vendor advisory or patch information is provided, so patch status is unknown.
