CVE-2025-71213· NVD / CVE Program· CNA trendmicro

An origin validation error vulnerability in Trend Micro Apex One could allow a local attacker to escalate privileges on affected installatio

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Trend Micro, Inc. TrendAI Apex One 14.0.0.14136; Trend Micro, Inc. TrendAI Apex One as a Service 14.0.20315.

Low priority for now. Upgrade to Trend Micro, Inc. TrendAI Apex One 14.0.0.14136; Trend Micro, Inc. TrendAI Apex One as a Service 14.0.20315 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

An origin validation error vulnerability in Trend Micro Apex One could allow a local attacker to escalate privileges on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
