CVE-2024-28065

Sensitive data extraction via unencrypted firmware files

Published Apr 5, 2024 · Updated Mar 28, 2025

Cleartext storage in Unify OpenScape Desk Phone CP firmware allows physically proximate attackers to extract sensitive data. The firmware image stores files without encryption, including a root password hash, so offline extraction exposes embedded credentials. Exploitation requires unauthenticated physical access to the phone and does not reportedly alter service operation.
