Executive Summary

CVE-2024-39724 is a vulnerability in IBM Db2 Big SQL on Cloud Pak for Data versions 7.8 and earlier. It occurs because the system does not properly limit resource allocation due to a lack of throttling on an API.

This flaw allows an authenticated user who has internal knowledge of the system to cause a denial of service (DoS) by exhausting system resources.

The vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling.

Impact Analysis

This vulnerability can impact you by allowing an authenticated user with some internal knowledge to cause a denial of service (DoS) condition.

The attacker can exhaust system resources, making the affected IBM Db2 Big SQL service unavailable or degraded, which impacts availability.

There is no impact on confidentiality or integrity, but the availability of the service is highly affected.

Mitigation Strategies

The recommended immediate step to mitigate this vulnerability is to upgrade IBM Db2 Big SQL to version 8.2 or later, which is available on Cloud Pak for Data 5.2 or later.

No workarounds or other mitigations are provided, so upgrading is the primary remediation.
