Trend Micro Apex Central RCE Flaw Scores 9.8 CVSS in On-Prem Windows Versions

Trend Micro patched a critical remote code execution vulnerability (CVE-2025-69258) in Apex Central on-prem Windows, achieving a CVSS score of 9.8, and two denial-of-service vulnerabilities (CVE-2025-69259 & CVE-2025-69260). The flaw impacts versions below build 7190 and impacts the LoadLibraryEX process.

Why This Matters

Ideal security models assume limited network access and robust input validation; however, real-world systems often expose services and rely on complex inter-process communication. This flaw demonstrates how a simple crafted message can lead to arbitrary code execution with SYSTEM privileges, potentially impacting an entire network. Successful exploitation of an RCE vulnerability can lead to complete system compromise, data breaches, and significant financial losses for organizations utilizing Apex Central.

Key Insights

• CVE-2025-69258: A critical RCE vulnerability in Apex Central’s LoadLibraryEX, rated 9.8 CVSS.
• Message-based exploitation: Attackers trigger vulnerabilities by sending specific messages (e.g., 0x0a8d, 0x1b5b) to the MsgReceiver.exe component.
• Tenable’s discovery: Tenable reported the vulnerabilities in August 2025, highlighting the importance of third-party security research.
