CVE-2024-20503

Estado: AnalizadaMedia (5.5)—

A vulnerability in Cisco Duo Epic for Hyperdrive could allow an authenticated, local attacker to view sensitive information in cleartext on an affected system.

This vulnerability is due to improper storage of an unencrypted registry key. A low-privileged attacker could exploit this vulnerability by viewing or querying the registry key on the affected system. A successful exploit could allow the attacker to view sensitive information in cleartext.
