CVE-2025-31284 is a vulnerability classified under CWE-269 (Improper Privilege Management) found in Trend Micro's Trend Vision One security platform. The flaw existed in the Status component, where an administrator could create new user accounts that were capable of modifying their own roles, effectively escalating their privileges beyond intended limits. This broken access control issue could allow attackers with initial administrative access to expand their control within the system, potentially compromising confidentiality and integrity of security monitoring data. The vulnerability requires an attacker to have administrative privileges initially and involves user interaction, which reduces the likelihood of remote exploitation by unauthorized users. The CVSS v3.1 base score is 4.6, indicating medium severity, with attack vector network-based, low attack complexity, privileges required, and user interaction needed. The vulnerability has been remediated by backend service updates, and no active exploits have been reported. Trend Vision One is a widely used security operations platform, so the vulnerability could have significant implications if exploited in unpatched environments.

If exploited, this vulnerability could allow an attacker with administrative access to escalate privileges by altering user roles, potentially gaining unauthorized control over security monitoring and management functions. This could lead to manipulation or suppression of security alerts, unauthorized access to sensitive data, and disruption of incident response activities. Although exploitation requires initial admin privileges, the ability to escalate privileges undermines the principle of least privilege and could facilitate further attacks within the network. Organizations relying on Trend Vision One for centralized security operations could face increased risk of insider threats or lateral movement by attackers. The absence of known exploits and backend remediation reduces immediate risk, but unpatched or misconfigured deployments remain vulnerable. The medium severity rating reflects moderate impact on confidentiality and integrity, with no direct availability impact.

Organizations should verify that their Trend Vision One deployments are running the latest backend service versions where this vulnerability has been addressed. Conduct thorough audits of user roles and permissions within Trend Vision One to ensure no unauthorized privilege escalations are possible. Implement strict administrative access controls and monitor administrative activities for suspicious behavior. Employ multi-factor authentication for all administrative accounts to reduce risk of credential compromise. Regularly review and update security policies related to user management in Trend Vision One. If possible, isolate the Trend Vision One management interface to trusted networks and restrict access via network segmentation and firewall rules. Maintain up-to-date incident response plans to quickly detect and respond to any suspicious privilege escalations. Engage with Trend Micro support for any additional patches or guidance related to this vulnerability.
