CVE-2020-5032

Temporary service interruption

Published Feb 4, 2021 · Updated Sep 16, 2024

Denial of service in IBM QRadar SIEM 7.3 and 7.4 allows remote attackers on an adjacent network to interrupt service with crafted payloads. IBM has not disclosed the affected component, payload format, or operation that mishandles the payload in vulnerable configurations. No authentication or user interaction is required, but exploitation has high complexity and causes only a temporary service interruption.
