CVE-2025-71210 — Trendmicro Apex One security vulnerability

Critical CVSS 9.8

A vulnerability in the Trend Micro Apex One management console could allow a remote attacker to upload malicious code and execute commands on affected installations. Please note: although this vulnerability carries a technical critical CVSS rating, this was reported via responsible disclosure via a researcher through the Zero Day Initiative. The SaaS versions of the product have already been mitigated and no customer action required. For this particular vulnerability, an attacker must have access to the Trend Micro Apex One Management Console, so customers that have their console�s IP address exposed externally should consider mitigating factors such as source restrictions if not already applied.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
