CVE-2024-47965
📋 TL;DR
Delta Electronics CNCSoft-G2 has a buffer over-read vulnerability (CWE-125) that allows attackers to read memory beyond allocated buffers. This can lead to information disclosure or be combined with other vulnerabilities for code execution. Industrial control systems using CNCSoft-G2 for CNC machine programming and monitoring are affected.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to full compromise of CNC systems, potential manipulation of manufacturing processes, production disruption, or safety incidents.
Likely Case
Information disclosure from memory, potential denial of service, or limited code execution within the CNCSoft-G2 process context.
If Mitigated
Limited impact with proper network segmentation and application sandboxing, potentially only information disclosure without code execution.
🎯 Exploit Status
Requires user interaction (opening malicious file/website). Exploit would need to bypass ASLR/DEP protections for reliable code execution.
🛠️ Fix & Mitigation
