CVE-2025-36193 is a high-severity vulnerability affecting IBM Transformation Advisor versions 2.0.1 through 4.3.1. The root cause is an incorrect permission assignment (CWE-732) on security-critical files within the container image used by the IBM Transformation Advisor Operator Catalog. Specifically, these files are assigned privileges that are too permissive, allowing a local attacker with access inside the container to escalate their privileges to root. This vulnerability is particularly critical because it enables privilege escalation inside a containerized environment, which is often considered a security boundary. The vulnerability does not require prior authentication or user interaction, and the attack vector is local (AV:L), meaning the attacker must have some level of access to the container environment. The CVSS v3.1 base score is 8.4, reflecting high impact on confidentiality, integrity, and availability, as a root escalation can lead to full system compromise. The vulnerability affects the IBM Transformation Advisor product, which is used to analyze and assist in application modernization and migration efforts, often deployed in enterprise environments including container orchestration platforms. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that organizations should prioritize mitigation and monitoring to prevent exploitation.

For European organizations, this vulnerability poses a significant risk especially for enterprises leveraging IBM Transformation Advisor in containerized environments for application modernization projects. Successful exploitation could allow attackers to gain root privileges inside containers, potentially leading to lateral movement within the host or cluster, data exfiltration, or disruption of critical modernization workflows. Given the critical role of IBM Transformation Advisor in digital transformation initiatives, exploitation could delay projects, cause data integrity issues, or lead to exposure of sensitive application data. Additionally, the compromise of container environments could impact compliance with European data protection regulations such as GDPR, especially if personal data is processed or stored within affected systems. The local attack vector means that attackers would need initial access to the container environment, which could be achieved through other vulnerabilities or insider threats, emphasizing the need for layered security controls.

1. Immediate mitigation should include restricting access to container environments running IBM Transformation Advisor Operator Catalog images to trusted personnel only, minimizing the risk of local exploitation. 2. Implement strict container runtime security policies using tools like AppArmor, SELinux, or seccomp to limit the capabilities of containers and prevent privilege escalation. 3. Monitor container logs and audit trails for suspicious activity indicative of privilege escalation attempts. 4. Employ network segmentation and zero-trust principles to limit lateral movement if a container is compromised. 5. Since no patches are currently linked, coordinate with IBM support for any available workarounds or upcoming patches and plan for rapid deployment once available. 6. Review and harden file permissions within container images if possible by rebuilding images with corrected permissions. 7. Conduct regular vulnerability scans and penetration tests focusing on container security to detect and remediate similar issues proactively.
