CVE-2026-78492Network attack vector

Unauthorized access via improper certificate validation

Published Sep 9, 2026 · Updated Sep 11, 2026

Improper certificate validation in Dell SCG Appliance before 5.36.00.16 and Application before 5.36.00.00 allows remote attackers unauthorized access. Dell has not published the affected certificate-validation locus or the incorrect operation performed on an untrusted certificate. Exploitation requires unauthenticated remote access and high attack complexity; successful exploitation compromises confidentiality and integrity without a reported availability impact.
