Trend Micro Apex One On-Premise Command Injection Vulnerability

Historical catalog analysis: CISA added this entry on August 18, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-54948 is an OS command injection vulnerability (CWE-78) identified in the Trend Micro Apex One Management Console. This flaw allows a remote, pre-authenticated attacker to upload malicious code and execute commands on affected installations. Because this occurs at the management console level, it represents a significant risk to the integrity of the security infrastructure managing endpoint protection across a healthcare network.

Exposure and applicability

This vulnerability specifically affects on-premise installations of the Trend Micro Apex One Management Console. Healthcare providers, health plans, and business associates who maintain their own local management servers for endpoint security are within the scope of this risk. Organizations utilizing cloud-based versions of the service may have different exposure profiles, as the source specifies the on-premise console.

For HIPAA-covered entities, a compromise of the security management console could potentially lead to unauthorized access to systems containing electronic Protected Health Information (ePHI) or disrupt the continuity of patient care by disabling endpoint protections across the clinical environment.

Remediation priorities

Based on our analysis, organizations should prioritize the following actions to reduce the likelihood of exploitation:

1. Immediate Version Audit: IT administrators should verify if they are running an affected on-premise version of Apex One. This is the primary step in determining if the organization is exposed.
2. Apply Vendor Mitigations: Following Trend Micro’s official instructions to apply available patches or mitigations is the most direct method to address the command injection flaw.
3. Network Segmentation Review: Security leaders should evaluate whether the management console is unnecessarily exposed to broad network segments. Restricting access to the console to authorized administrative workstations could limit the reach of a pre-authenticated remote attacker.
4. Decommissioning Evaluation: In scenarios where mitigations are unavailable or cannot be applied due to legacy system constraints, organizations should consider discontinuing use of the affected product to eliminate the risk.

How to validate remediation

To verify that exposure has been reduced, administrators can perform the following checks:
* Version Verification: Confirm through the management console’s system information that the installed version matches the patched or mitigated version specified by the vendor.
* Access Control Audit: Review firewall and Access Control List (ACL) logs to ensure that only authorized IP addresses can communicate with the Apex One Management Console port, reducing the remote attack surface.

Note: We do not recommend performing active penetration testing or attempting to trigger command injection on production medical systems or security consoles, as this could cause operational instability.

Limits and open questions

While CISA has added this vulnerability to its Known Exploited Vulnerabilities catalog, the source indicates that use in known ransomware campaigns is currently “Unknown.” It remains unclear exactly which versions of Apex One are affected beyond the general product identification. Furthermore, while patching reduces the likelihood of exploitation, it does not guarantee total prevention if other systemic vulnerabilities exist within the network architecture.
