CVE-2020-4216Network attack vector

Unauthenticated Discovery Server access via hard-coded password

Published Jun 15, 2020 · Updated Sep 16, 2024

Authentication bypass in IBM Spectrum Protect Plus 10.1.0 through 10.1.5 allows remote attackers to access the Discovery Server. The login-request handler accepts a hard-coded account password instead of requiring installation-specific credentials. No authentication is required; successful use exposes protected Discovery Server data, with no vendor-reported integrity or availability impact.
