Who should care

Users of IBM Cognos Analytics 12.1.3 GA Version with build number through 12.1.3-2606251736 should be aware of this vulnerability and take necessary precautions. This includes operators, administrators, and security teams responsible for the platform, as they need to assess the impact, apply patches or mitigations, and monitor for potential exploitation attempts.

Technical summary

The vulnerability exists in the Agentic AI assistant's concurrent request-handling logic of IBM Cognos Analytics 12.1.3 GA Version with build number through 12.1.3-2606251736. When multiple authenticated users submit report-related tasks simultaneously, an attacker could obtain incorrect report summary results or cause report-processing failures due to a race condition. This issue arises from inadequate handling of concurrent requests, potentially leading to incorrect report summary results or report-processing failures.

Defensive priority

Medium priority. Organizations should prioritize patching or mitigating this vulnerability to prevent potential report-processing failures or incorrect report summary results. Compensating controls and monitoring should be implemented to detect and respond to potential exploitation attempts until a patch is applied. Review compensating controls for exposed systems while remediation is scheduled and verified. Check relevant monitoring, detection, and logs for exposed assets that need extra review. Track exceptions, retest remediated assets, and close the item only after evidence is documented. Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up. Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Consider asset inventory and source tracking to ensure comprehensive vulnerability management. Rollback or change windows may be necessary for remediation efforts. Exposure review should be conducted to understand the potential impact on the organization. Monitoring and detection capabilities should be evaluated to ensure they can identify potential exploitation attempts. A thorough review of the vulnerability and its potential impact on the organization is necessary to ensure adequate protection. This vulnerability may require additional security measures to prevent exploitation, such as implementing additional logging or monitoring to detect suspicious activity. It is essential to review the official advisory and CVE record to understand the vulnerability and its potential impact on the organization. The organization should also consider implementing compensating controls, such as additional security measures or workarounds, to mitigate the vulnerability until a patch is applied. The organization should prioritize patching or mitigating this vulnerability to prevent potential report-processing failures or incorrect report summary results. The organization should also consider conducting a thorough review of its security controls and procedures to ensure
