CVE-2026-24497

Code execution via undisclosed stack buffer overflow

Published Feb 27, 2026 · Updated Feb 27, 2026

Stack-based buffer overflow in SimTech Systems ThinkWise 7 through 22 allows attackers to execute code via unspecified input. The CNA and KrCERT/CC advisory do not identify the affected parser, input field, or unsafe copy operation. The CNA assessment places the attack locally, requires no privileges, and requires passive user interaction; successful exploitation executes attacker-controlled code.
