CVE-2025-3473 is a vulnerability identified in IBM Security Guardium version 12.1, categorized under CWE-277, which pertains to Insecure Inherited Permissions. The flaw arises from the way the software sets permissions on certain resources, allowing a local user with elevated privileges (but not root) to escalate their privileges to root. This escalation is possible because the program creates insecure inherited permissions that can be exploited by a local privileged user to gain full administrative control over the system. The vulnerability requires local access and a user with high privileges, but does not require user interaction beyond executing the exploit. The CVSS v3.1 base score is 6.7, indicating a medium severity level. The attack vector is local (AV:L), with low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (all high). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's root cause is improper permission inheritance, which is a common security misconfiguration that can lead to privilege escalation if not properly managed. IBM Security Guardium is a data security and protection platform widely used in enterprise environments to monitor and protect databases and sensitive data assets.

For European organizations, this vulnerability poses a significant risk especially to enterprises relying on IBM Security Guardium 12.1 for database activity monitoring and data security compliance. Successful exploitation could allow an attacker with local privileged access to gain root-level control, potentially leading to full system compromise. This could result in unauthorized access to sensitive data, disruption of security monitoring capabilities, and the ability to disable or manipulate security controls. Given the critical role Guardium plays in regulatory compliance (e.g., GDPR), exploitation could lead to data breaches, regulatory fines, and reputational damage. The requirement for local privileged access somewhat limits remote exploitation, but insider threats or attackers who have already gained some elevated access could leverage this vulnerability to escalate privileges further. The impact on confidentiality, integrity, and availability is high, as root access enables complete control over the affected system.

Organizations should immediately audit their IBM Security Guardium 12.1 deployments to identify any instances of insecure inherited permissions. Until an official patch is released, administrators should implement strict access controls to limit local privileged user accounts and monitor for unusual privilege escalation attempts. Employing file system permission audits and using tools to detect improper permission inheritance can help identify vulnerable configurations. Additionally, organizations should enforce the principle of least privilege, ensuring that users have only the minimum necessary permissions. Restricting physical and local access to Guardium servers is critical. Monitoring system logs for suspicious activity related to privilege changes or unauthorized access attempts is also recommended. Once IBM releases a patch or update, organizations should prioritize timely deployment. In parallel, consider implementing host-based intrusion detection systems (HIDS) to detect and alert on privilege escalation attempts.
