CVE-2021-29780Network attack vector

Authenticated unauthorized action via improper input validation

Published Jul 19, 2021 · Updated Sep 16, 2024

Improper input validation in IBM Security QRadar SOAR version 41 allows remote authenticated users to perform unauthorized actions. The advisory does not identify a specific endpoint or parameter; it states that crafted input bypasses intended authorization checks. Access requires an authenticated account, and the bounded impact is execution of actions beyond that account's permissions, with no evidence of unauthenticated access or direct service compromise.
