CVE-2025-3473 is a vulnerability identified in IBM Security Guardium version 12.1, categorized under CWE-277: Insecure Inherited Permissions. The flaw arises from the program creating insecure inherited permissions on certain resources, which can be exploited by a local privileged user to escalate their privileges to root. Specifically, the vulnerability allows an attacker who already has some level of privileged access on the system (but not root) to leverage improperly set permissions inherited by files or processes managed by Security Guardium, thereby gaining full root-level control. This escalation can lead to complete system compromise, including unauthorized access to sensitive data, modification or deletion of critical files, and disruption of system availability. The CVSS v3.1 base score is 6.7, reflecting a medium severity level. The vector indicates that the attack requires local access (AV:L), low attack complexity (AC:L), high privileges (PR:H), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches have been linked yet. IBM Security Guardium is a data security and protection platform widely used for database activity monitoring and compliance enforcement, often deployed in enterprise environments to safeguard critical data assets.

For European organizations, this vulnerability poses a significant risk, particularly for those relying on IBM Security Guardium 12.1 to protect sensitive databases and comply with stringent data protection regulations such as GDPR. Successful exploitation could lead to unauthorized root access, enabling attackers to bypass security controls, access or manipulate confidential data, and disrupt business operations. This could result in data breaches, regulatory penalties, reputational damage, and operational downtime. Given that the vulnerability requires local privileged access, the threat is more pronounced in environments where multiple users have elevated privileges or where attackers can gain initial footholds through other means. The comprehensive impact on confidentiality, integrity, and availability underscores the criticality of addressing this issue promptly to maintain trust and compliance in European markets.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately audit and review the permission settings on all files and processes related to IBM Security Guardium 12.1 to identify and correct insecure inherited permissions. 2) Restrict local privileged access strictly to trusted administrators and implement robust access controls and monitoring to detect unauthorized privilege escalations. 3) Employ application whitelisting and integrity monitoring to detect anomalous changes in Security Guardium components. 4) Isolate Security Guardium servers from general user environments to minimize the risk of local privilege abuse. 5) Monitor system logs and security alerts for suspicious activities indicative of privilege escalation attempts. 6) Engage with IBM support to obtain patches or workarounds as soon as they become available and plan for timely deployment. 7) Conduct regular security training for administrators to recognize and prevent privilege misuse. These steps go beyond generic advice by focusing on permission auditing, access restriction, and proactive monitoring tailored to the specific nature of this vulnerability.
