CVE-2022-43908Network attack vector

Authenticated service interruption via improper input validation

Published Jul 19, 2023 · Updated Oct 21, 2024

Improper input validation in IBM Security Guardium 11.3 allows remote authenticated users to interrupt service through a network request. IBM has not identified the affected interface, input field, validation failure, or resulting failure mode beyond denial of service. A valid account is required, and published evidence supports an availability impact only; it does not establish whether exploitation causes a hang, crash, or reboot.
