CVE-2024-11609

Code execution via unchecked EAP9 copy length

Published Jan 30, 2025 · Updated Feb 10, 2025

Stack-based buffer overflow in AutomationDirect C-more EA9 Programming Software 6.78 and earlier allows remote attackers to execute code. The EAP9 parser copies user-supplied data into a fixed-length stack buffer without validating the input length, allowing the copy to overwrite process memory. Exploitation requires the target to visit a malicious page or open a crafted EAP9 file, and successful exploitation runs code in the current process context.
