CVE-2025-33003 is a vulnerability classified under CWE-250 (Execution with Unnecessary Privileges) affecting IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6. The flaw arises because certain processes within the containerized deployment of InfoSphere run with elevated privileges unnecessarily, allowing a non-root user to escalate their privileges within the container scope. This privilege escalation can lead to unauthorized access to sensitive data, modification of critical information, or disruption of services. The vulnerability has a CVSS v3.1 base score of 7.8, indicating high severity, with attack vector local (AV:L), attack complexity high (AC:H), privileges required low (PR:L), no user interaction (UI:N), and scope changed (S:C). The impact on confidentiality, integrity, and availability is high, meaning an attacker could fully compromise the container environment. Although no public exploits are known, the vulnerability poses a significant risk in environments where InfoSphere is deployed in containers and accessed by multiple users with varying privilege levels. The lack of available patches at the time of publication necessitates immediate mitigation efforts by administrators.

The vulnerability allows attackers with low-level access to escalate privileges within the container, potentially gaining control over sensitive data processing and management functions of IBM InfoSphere Information Server. This can lead to data breaches, unauthorized data manipulation, and service disruption. Given InfoSphere's role in enterprise data integration and governance, exploitation could compromise critical business intelligence and analytics workflows. The containerized nature of the deployment means that the impact is scoped to the container but can still affect multi-tenant environments or systems relying on container isolation. Organizations worldwide using affected versions risk exposure of confidential data and operational interruptions, which could result in financial loss, reputational damage, and regulatory penalties.

1. Apply patches or updates from IBM as soon as they become available to address CVE-2025-33003. 2. Until patches are released, restrict access to InfoSphere containers to trusted users only and enforce strict access controls. 3. Review and minimize privileges assigned to processes within the container to ensure the principle of least privilege is followed. 4. Implement container security best practices such as running containers with non-root users and disabling unnecessary capabilities. 5. Monitor container logs and system behavior for unusual privilege escalation attempts or suspicious activities. 6. Use container runtime security tools to enforce security policies and detect privilege misuse. 7. Conduct regular security audits and vulnerability assessments on containerized deployments of InfoSphere. 8. Segment network and data access to limit the blast radius if a container is compromised.
