CVE-2024-22457Network attack vector

Authenticated server impersonation via self-signed certificate

Published Mar 1, 2024 · Updated Aug 15, 2024

Improper authentication in Dell Secure Connect Gateway 5.20 allows remote authenticated users to impersonate its server during migration. The SRS-to-SCG update path accepts a presented self-signed certificate without adequately authenticating the remote endpoint. Low-privileged access and user interaction are required; successful spoofing lets the attacker communicate as the trusted remote server.
