CVE-2023-31925Network attack vector

SNMP credential disclosure via plaintext SupportSave logs

Published Aug 31, 2023 · Updated Sep 27, 2024

Cleartext credential storage in Brocade SANnav releases before 2.2.2a or 2.3.0 allows remote authenticated users to read SNMPv3 passwords. A failed SNMP configuration causes the communication log dump included in a subsequent SupportSave capture to record authentication passwords without encryption. The leak requires privileged access to the captured log files after such a failure and exposes credentials used for managed SNMP endpoints.
