CVE-2026-78020
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk7th percentile - higher than 7% of all known CVEs
Summary
Dell Secure Connect Gateway (SCG) Policy Manager versions prior to 5.34.00.16 contain an Improper Certificate Validation vulnerability. An unauthenticated attacker with remote access could exploit it to cause denial of service, information disclosure, and remote execution.
Risk Assessment
Improper certificate validation allows an attacker to impersonate a trusted server, potentially leading to data interception, denial of service, or remote code execution on the system.
Recommendation
Update Dell Secure Connect Gateway Policy Manager to version 5.34.00.16 or later. Ensure proper certificate chain validation and avoid disabling certificate verification in the configuration.
