CVE-2020-4477Network attack vector

Sensitive information exposure via plaintext virgo logging

Published Jun 15, 2020 · Updated Sep 16, 2024

Plaintext logging in IBM Spectrum Protect Plus 10.1.0 through 10.1.5 allows remote authenticated users to read sensitive information. The application writes highly sensitive information to the virgo log file in plaintext instead of excluding or protecting it. Low-privileged access and a high-complexity path are required; disclosed data can support further attacks against the appliance.
