CVE-2025-33003 is a vulnerability identified in IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6, where the software executes certain processes with unnecessary elevated privileges inside containerized environments. This flaw corresponds to CWE-250, which involves execution with excessive privileges that are not required for the intended functionality. Specifically, a non-root user with limited privileges inside the container can exploit this vulnerability to gain higher privileges or capabilities within the container scope. The vulnerability is local (AV:L), requires low privileges (PR:L), has high attack complexity (AC:H), and does not require user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially compromised component. The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating that an attacker could fully compromise the affected system's data and operations. Although no public exploits have been reported, the vulnerability poses a significant risk due to the critical role of IBM InfoSphere in enterprise data integration, governance, and analytics workflows. The lack of available patches increases the urgency for organizations to implement compensating controls. The vulnerability arises from improper privilege management within containerized deployments, which could allow privilege escalation attacks, potentially leading to unauthorized data access, data manipulation, or service disruption.

For European organizations, the impact of CVE-2025-33003 can be severe, especially for those relying on IBM InfoSphere Information Server for critical data integration, governance, and analytics. Successful exploitation could allow attackers to escalate privileges within container environments, leading to unauthorized access to sensitive data, manipulation of data pipelines, or disruption of business-critical services. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), operational downtime, and reputational damage. Industries such as finance, healthcare, telecommunications, and government agencies in Europe that use IBM InfoSphere extensively are particularly at risk. The containerized nature of the deployment means that lateral movement within the environment is possible, potentially compromising other containerized applications or services. The high confidentiality, integrity, and availability impacts underscore the critical need for timely mitigation to prevent exploitation that could affect large-scale data processing and analytics operations.

Since no official patches are currently available, European organizations should implement the following specific mitigations: 1) Review and minimize the privileges assigned to IBM InfoSphere containers, ensuring the principle of least privilege is strictly enforced. 2) Harden container runtime environments by disabling unnecessary capabilities and using security modules such as SELinux or AppArmor to restrict process actions. 3) Implement strict access controls and authentication mechanisms to limit local user access to the container hosts and InfoSphere environments. 4) Monitor container logs and system events for unusual privilege escalations or suspicious activity indicative of exploitation attempts. 5) Employ network segmentation to isolate containerized InfoSphere deployments from other critical infrastructure. 6) Prepare incident response plans specifically addressing container privilege escalation scenarios. 7) Stay informed on IBM security advisories for forthcoming patches and apply them promptly once released. 8) Conduct regular security audits and penetration testing focused on container privilege boundaries. These targeted actions go beyond generic advice by focusing on container-specific privilege management and monitoring.
