CVE-2022-40235 is a vulnerability identified in IBM InfoSphere Information Server version 11.7, which could allow an authenticated user with limited privileges to cause a denial of service (DoS) condition. The root cause is improper input validation, classified under CWE-20, which allows the attacker to disrupt the normal operation of the server by removing the ability to run jobs. This vulnerability does not affect confidentiality or integrity but impacts availability by preventing job execution, which is critical in data integration and ETL (Extract, Transform, Load) processes that InfoSphere facilitates. The CVSS v3.1 base 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 impact on confidentiality or integrity (C:N/I:N), and high impact on availability (A:H). No known exploits have been reported in the wild, and no official patches are currently linked in the provided data. The vulnerability requires an authenticated user with some privileges, which suggests that internal or compromised users could exploit this flaw to disrupt data workflows. Given the critical role of IBM InfoSphere Information Server in enterprise data management, this DoS could significantly affect business operations relying on timely data processing and integration.

For European organizations, the impact of this vulnerability can be significant, especially for enterprises and public sector entities relying on IBM InfoSphere Information Server for data integration, analytics, and business intelligence. The denial of service can halt critical data processing jobs, leading to delays in reporting, decision-making, and operational workflows. Industries such as finance, telecommunications, manufacturing, and government agencies that depend on continuous data pipelines may experience operational disruptions, potential regulatory compliance issues due to delayed data availability, and increased recovery costs. Since the vulnerability requires authenticated access, insider threats or compromised credentials pose a realistic risk vector. The disruption of data jobs could also affect downstream systems and services, amplifying the operational impact. While no data breach or data corruption is indicated, the unavailability of data services can indirectly affect business continuity and service level agreements (SLAs).

1. Implement strict access controls and monitor user privileges to limit the number of users with job execution rights in IBM InfoSphere Information Server. 2. Conduct regular audits of user accounts and sessions to detect anomalous activities that could indicate exploitation attempts. 3. Employ network segmentation and firewall rules to restrict access to the InfoSphere server to trusted internal networks and users only. 4. Since no official patch is currently linked, consider deploying application-level input validation or filtering mechanisms where possible to mitigate improper input risks. 5. Establish robust incident response procedures to quickly identify and recover from denial of service conditions affecting job execution. 6. Engage with IBM support or security advisories to obtain any forthcoming patches or workarounds. 7. Use multi-factor authentication (MFA) for all users accessing the system to reduce the risk of credential compromise. 8. Implement job scheduling redundancy or failover mechanisms to minimize operational impact if the primary job execution is disrupted. 9. Monitor logs and system metrics for early signs of job execution failures or unusual input patterns that could indicate exploitation attempts.
