Critical SQLite Vulnerability in Siemens Industrial Controllers Enables Code Execution
A high-severity numeric truncation error in SQLite within Siemens RUGGEDCOM CROSSBOW controllers allowed attackers with low privileges to achieve arbitrary code execution and denial of service through memory corruption. This vulnerability (CVE-2025-6965) affects critical manufacturing infrastructure worldwide, demonstrating how third-party library flaws can create serious attack vectors in industrial control systems. The flaw's ability to escalate low-privilege access to full code execution highlights the critical importance of maintaining current patches on operational technology systems. Immediate patching to version 5.8 is essential to prevent potential manufacturing disruptions or safety incidents.
