LiveThreat Vulnerability Brief — CVE-2025-71213
What It Is — Trend Micro Apex One contains an origin‑validation error in its NT Listener service that permits a local attacker to elevate privileges to SYSTEM and execute arbitrary code. Exploitability — Requires prior low‑privilege code execution on the host; no public exploit or PoC disclosed, but the vulnerability is actively exploitable once foothold is gained. CVSS 7.8 (High).
Affected Products — Trend Micro Apex One (Security Agent).
TPRM Impact — Apex One is widely deployed by enterprises and managed‑service providers to protect endpoints; a compromised agent can undermine endpoint security controls, enabling lateral movement and data exposure across the supply chain.
Recommended Actions — 1) Apply Trend Micro’s remediation update (KB KA‑0022458) immediately on all endpoints. 2) Verify version numbers to confirm patch deployment. 3) Monitor for anomalous SYSTEM‑level activity and unauthorized command execution. 4) Enforce least‑privilege for services and isolate the Apex One agent where possible.
