CVE-2022-23141Network attack vector

Sensitive information disclosure via ineffective ZBOOT authentication

Published Jul 15, 2022 · Updated Aug 3, 2024

Information disclosure in ZTE Corporation ZXMP M721 firmware COMMOND21BOOTV100004_LS1045 allows remote attackers to obtain sensitive information. The ZBOOT serial-port interface accepts authentication as enabled even though the check is ineffective, allowing login without valid authentication. Access requires network reachability to the device interface; the documented consequence is confidential-information exposure without integrity or availability impact.
