CVE-2021-26999Network attack vector

Sensitive data disclosure via failed-connection logging

Published Aug 6, 2021 · Updated Aug 3, 2024

Information disclosure in NetApp Cloud Manager before 3.9.9 allows remote authenticated users to read sensitive data from logs. The Active Directory connection-failure path writes sensitive connection information to logs instead of omitting it. A failed connection must occur, and access is limited to authenticated users; no integrity or availability impact is reported.
