Alert meAnalysisAI
IBM MQ 9.1.0.0, 9.1.0.1, 9.1.1, and 9.1.0.2 is vulnerable to a denial of service due to a local user being able to fill up the disk space of the underlying filesystem using the error logging service. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. This Uncontrolled Resource Consumption vulnerability could allow attackers to cause denial of service by exhausting system resources.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Implement rate limiting, set resource quotas, validate input sizes, use timeouts.
