CVE-2021-39006Network attack vector

Unauthenticated sensitive information disclosure

Published Jun 21, 2022 · Updated Sep 16, 2024

Information disclosure in IBM QRadar WinCollect Agent 10.0 and 10.0.1 allows remote attackers to obtain sensitive information. IBM describes only “missing best practices” and does not identify the affected component, request, data source, or incorrect operation. Network access requires no authentication or user interaction, and the published impact is limited to sensitive-information exposure without integrity or availability effects.
