CVE-2025-36094 is a vulnerability identified in IBM Cloud Pak for Business Automation versions 24.0.0 through 25.0.0 Interim Fix 002. The root cause is improper validation of the specified quantity in input, classified under CWE-1284. This flaw allows an authenticated user to submit input with improperly validated length parameters, which can lead to denial of service (DoS) conditions or corruption of existing data within the application. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based, meaning an attacker can exploit it remotely once authenticated. The CVSS v3.1 base score is 5.4, indicating a medium severity level, with impact on integrity and availability but no confidentiality loss. The vulnerability affects multiple recent versions of IBM Cloud Pak for Business Automation, a platform widely used for automating business processes and workflows. While no public exploits are currently known, the potential for disruption in business-critical automation tasks is significant. The improper input validation could cause application crashes or data inconsistencies, potentially impacting business operations relying on automated workflows. IBM has not yet published patches or interim fixes specifically addressing this issue, so organizations must monitor for updates and apply them promptly once available.

For European organizations, the impact of CVE-2025-36094 can be substantial, especially for those relying heavily on IBM Cloud Pak for Business Automation to manage critical business processes. The vulnerability can lead to denial of service, causing interruptions in automated workflows and business operations, which may result in financial losses and operational delays. Data corruption risks threaten the integrity of business data, potentially leading to erroneous processing outcomes or compliance issues if corrupted data is used in reporting or decision-making. Since the vulnerability requires authenticated access, insider threats or compromised credentials could be leveraged to exploit this flaw. The disruption of automation services could also affect supply chain management, customer service, and regulatory reporting, which are critical in sectors such as finance, manufacturing, and public services prevalent in Europe. The absence of confidentiality impact reduces risks related to data breaches but does not diminish the operational risks posed by availability and integrity compromises.

European organizations should implement a multi-layered mitigation approach: 1) Restrict and monitor authenticated user access to IBM Cloud Pak for Business Automation, enforcing least privilege principles to minimize the risk of exploitation. 2) Closely monitor IBM’s security advisories for patches or interim fixes addressing CVE-2025-36094 and apply them promptly once released. 3) Implement input validation controls and anomaly detection within the application environment to detect and block abnormal input lengths or patterns that could trigger the vulnerability. 4) Conduct regular audits of user activities and access logs to identify potential misuse or exploitation attempts. 5) Employ network segmentation and access controls to limit exposure of the affected systems to only trusted users and networks. 6) Prepare incident response plans specifically addressing potential denial of service or data corruption scenarios to minimize downtime and data loss. 7) Engage with IBM support to obtain guidance and potential workarounds until official patches are available.
