CVE-2020-5330Public exploitNetwork attack vector

Unauthenticated credential-hash disclosure via exposed admin endpoint

Published Apr 10, 2020 · Updated Sep 16, 2024

Information disclosure in Dell PowerConnect firmware allows remote attackers to retrieve credential hashes through crafted web requests. The unauthenticated web interface redirects to an API base path where config/device/adminusersetting returns usernames and SHA-1 password hashes without access control. Network access to the management interface is sufficient, and recovered hashes can be matched offline and used to authenticate as the compromised account.
