CVE-2021-22310

Admin-only disclosure via sensitive login data logging

Published Mar 22, 2021 · Updated Aug 3, 2024

Information disclosure in Huawei NIP and USG firmware allows local users with administrative access to read login data from logs. During device login, the server logging path stores sensitive information in a log file where a logged-in attacker can retrieve it. Successful access requires high privileges on the target system and affects confidentiality without reported integrity or availability impact.
