CVE-2025-54987 is an OS command injection vulnerability classified under CWE-78, affecting Trend Micro Apex One (on-premise) management console version 2019 (14.0). The flaw allows a remote attacker to upload malicious code and execute arbitrary commands on the affected system without requiring authentication or user interaction. This vulnerability is similar to CVE-2025-54948 but targets a different CPU architecture, indicating that multiple hardware platforms running the same software are vulnerable. The vulnerability arises from improper input validation in the management console, enabling attackers to inject OS commands that the system executes with elevated privileges. The CVSS v3.1 score of 9.4 highlights the critical nature of this flaw, with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact includes full confidentiality compromise, partial integrity loss, and high availability disruption, potentially allowing attackers to take control of the management console, manipulate endpoint security policies, or disrupt security operations. Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime candidate for exploitation by threat actors targeting enterprise environments. Trend Micro Apex One is widely deployed in enterprises globally, especially in sectors requiring robust endpoint protection such as finance, healthcare, government, and critical infrastructure. The lack of an available patch at the time of publication increases the urgency for organizations to implement interim mitigations and monitor for exploitation attempts.

The impact of CVE-2025-54987 is severe for organizations using Trend Micro Apex One on-premise management consoles. Successful exploitation allows attackers to execute arbitrary OS commands remotely without authentication, leading to potential full system compromise. This can result in unauthorized access to sensitive data, disruption or disabling of endpoint security controls, and potential lateral movement within the network. The confidentiality of organizational data is at high risk, as attackers could exfiltrate information or manipulate security logs. Integrity is partially impacted since attackers can modify configurations or security policies, potentially undermining the security posture. Availability is highly affected because attackers could disrupt or disable the management console, impairing the organization's ability to manage endpoint security effectively. Given the critical role of Apex One in enterprise security, exploitation could lead to widespread security failures and increased risk of further attacks. The vulnerability's ease of exploitation and lack of required privileges make it attractive for attackers, increasing the likelihood of targeted attacks against high-value organizations worldwide.

Organizations should prioritize applying official patches from Trend Micro as soon as they become available. Until patches are released, implement strict network segmentation to isolate the Apex One management console from untrusted networks and limit access to trusted administrators only. Employ firewall rules to restrict inbound traffic to the management console to known IP addresses. Enable and monitor detailed logging on the management console to detect suspicious activities such as unexpected file uploads or command executions. Conduct regular security audits and vulnerability scans to identify any signs of compromise. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this vulnerability. Educate administrators on the risks and signs of exploitation to improve incident response readiness. If possible, temporarily disable or restrict features that allow file uploads or command execution until the vulnerability is mitigated. Maintain up-to-date backups of management console configurations and endpoint security policies to enable rapid recovery in case of compromise.
