CVE-2025-54987
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in Trend Micro Apex One (on-premise) management console could allow a pre-authenticated remote attacker to upload malicious code and execute commands on affected installations. This vulnerability is essentially the same as CVE-2025-54948 but targets a different CPU architecture.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA pre-authenticated remote code execution vulnerability exists in the Trend Micro Apex One on-premise management console. An unauthenticated attacker can upload malicious code (likely a web shell or executable) through the management interface and achieve command execution on the underlying system. This CVE is architecturally distinct from CVE-2025-54948 but exploits the same underlying flaw.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Apex One versionLocate the installed version of Trend Micro Apex One. Check the management console About page, or inspect version information in the installation directory typically found at C:\Program Files\Trend Micro\Apex One\, or view the product via Windows Programs and Features.Affected if The installed version is exactly 2019 (version 2019)
-
Determine management console exposureIdentify network accessibility of the Apex One management console ports (commonly 4343, 443, 8080). Review firewall rules, NAT configurations, and any reverse proxy setups to determine if the console is reachable from untrusted networks.Affected if The management console port is exposed to the internet or untrusted internal networks without VPN or authentication protection
-
Inspect web root for web shellsExamine the web console directory (typically C:\Program Files\Trend Micro\Apex One\PCCSRV\Web_Console\) for unexpected files. Look for newly created or recently modified .asp, .aspx, .jsp, .php, .exe, or .dll files, especially those with random alphanumeric names.Affected if Unexpected script files, executables, or web shells are found in the web console directory
-
Review logs for upload anomaliesAnalyze Apex One management console logs and web server logs (usually in C:\Program Files\Trend Micro\Apex One\PCCSRV\Logs\) for suspicious POST requests to upload endpoints, particularly those containing unusual file extensions or attempts to bypass file type restrictions.Affected if Logs contain evidence of unauthorized file upload attempts or suspicious POST requests to the management interface
You are affected if Apex One version 2019 is installed AND the management console is network-accessible from untrusted sources, or if signs of compromise such as web shells or anomalous upload activity are found.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the vendor-supplied patch for CVE-2025-54987 immediately; if patches are unavailable, restrict network access to the management console using firewall rules or VPN access until the update can be deployed.
- Access the vendor patch reference at https://success.trendmicro.com/en-US/solution/KA-0020652 to obtain the specific patch or hotfix for this vulnerability
- Apply the vendor-supplied patch following the installation instructions provided in the knowledge base article
- After patching, verify the Apex One server is running correctly and monitor for any anomalous behavior
- Ensure the management console is not directly exposed to the internet; restrict access to trusted administrators only via VPN or firewall rules
