CVE-2026-49005

Root password hash disclosure via unencrypted firmware

Published Aug 7, 2026 · Updated Aug 7, 2026

Credential exposure in ZTE ZXHN F689 firmware allows physically proximate attackers to obtain the device's root password hash. The firmware stores the root password hash in unencrypted information, but ZTE has not disclosed the file, image region, hash scheme, or extraction procedure. Physical access to the appliance is required; the reported consequence is limited to disclosure of the hash, which can support offline password cracking.
