CVE-2022-48071Network attack vector

Credential disclosure via plaintext password storage

Published Jan 27, 2023 · Updated Mar 28, 2025

Cleartext credential storage in Phicomm K2 firmware 22.6.534.263 allows remote attackers to read root and admin passwords. The public advisory identifies only the firmware credential store, which retains both passwords without encryption and does not name a file or endpoint. Network reachability is scored as unauthenticated, but the disclosure path and required router configuration remain unpublished; the bounded impact is credential exposure.
