Administrator credential disclosure via exposed backup file

Published Apr 1, 2020 · Updated Aug 4, 2024

Credential exposure in Technicolor TC7337 firmware 8.89.17 allows remote attackers to obtain administrator credentials from a backup file. The configuration-backup function places recoverable administrator and Wi-Fi credentials in backupsettings.conf and makes the file retrievable. No authentication or user interaction is required; the direct effect is credential disclosure, with no documented modification or service interruption.
