CVE-2023-28076Network attack vector

Remote information disclosure via risky AES-GCM ciphers

Published May 16, 2023 · Updated Jan 22, 2025

Broken AES-GCM use in Dell CloudLink 7.1.2 and earlier allows remote attackers to disclose information through network access. Dell identifies the affected cryptographic primitive as AES-GCM but does not disclose the component, operation, or attacker-controlled input involved. Exploitation requires no authentication, has high complexity, and affects confidentiality without reported integrity or availability impact.
