CVE-2020-4850

Sensitive data disclosure via leftover configuration files

Published May 20, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Spectrum Scale Transparent Cloud Tiering 1.1.1.0 through 1.1.8.4 allows remote attackers to read sensitive data. Configuration handling leaves sensitive files behind where subsequent access can retrieve them; IBM has not disclosed the filenames or access path. The published description calls the attacker remote, while IBM's CVSS assessment models local access without privileges or user interaction.
