CVE-2025-36092 is a vulnerability classified under CWE-1284, which pertains to improper validation of specified quantity in input. This flaw exists in IBM Cloud Pak For Business Automation versions 24.0.0, 24.0.1, and 25.0.0. The vulnerability allows an authenticated user to submit input with improperly validated length parameters, which the system fails to handle correctly. This improper validation can cause the application to enter an unstable state, leading to denial of service (DoS) by crashing the service or consuming excessive resources. The vulnerability does not expose confidential data or allow unauthorized data modification, but it impacts the availability of the automation platform. The CVSS v3.1 score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality or integrity impact (C:N/I:N), and high availability impact (A:H). No public exploits are currently known, and no patches are linked yet, indicating that remediation may be pending or in progress. The vulnerability requires an attacker to have valid credentials, limiting exposure to authenticated users, but given the critical role of IBM Cloud Pak in business automation, the impact of service disruption can be significant. The improper input validation likely stems from insufficient checks on the length or quantity parameters in API calls or user inputs, which can be exploited to overwhelm the system or trigger unhandled exceptions.

For European organizations relying on IBM Cloud Pak For Business Automation, this vulnerability poses a risk of service disruption through denial of service attacks initiated by authenticated users. Such disruptions can halt critical business automation workflows, impacting operational efficiency and potentially causing financial losses. Since the vulnerability affects availability only, confidentiality and integrity of data remain intact. However, the loss of availability in automation platforms can cascade into broader business process interruptions, especially in sectors like finance, manufacturing, and public services where automation is integral. The requirement for authentication reduces the attack surface but does not eliminate risk, particularly if insider threats or compromised credentials are factors. Organizations with large-scale deployments or those integrating IBM Cloud Pak deeply into their IT infrastructure face higher operational risks. Additionally, the lack of current exploits in the wild provides a window for proactive mitigation before exploitation becomes widespread.

1. Monitor IBM’s official channels closely for patches or updates addressing CVE-2025-36092 and apply them promptly once available. 2. Restrict user privileges rigorously, ensuring that only trusted and necessary users have authenticated access to IBM Cloud Pak For Business Automation. 3. Implement input validation controls at the application and network layers to detect and block anomalous or excessively long input parameters that could trigger the vulnerability. 4. Employ rate limiting and anomaly detection on API endpoints to prevent abuse by authenticated users. 5. Conduct regular audits of user accounts and access logs to identify suspicious activities or potential credential compromise. 6. Develop and test incident response plans specifically for denial of service scenarios affecting business automation platforms. 7. Consider network segmentation to isolate critical automation services and reduce the blast radius of potential DoS attacks. 8. Educate administrators and users on the importance of credential security to mitigate insider threats or credential theft risks. 9. Use application-layer firewalls or web application firewalls (WAFs) capable of detecting unusual input patterns related to this vulnerability. 10. Engage with IBM support for guidance and potential workarounds until official patches are released.
