CVE-2019-25365Public exploit

Code execution via oversized configuration path

Published Feb 18, 2026 · Updated Feb 18, 2026

Stack-based buffer overflow in ChaosPro 2.0 allows attackers to execute arbitrary code through a crafted ChaosPro.cfg file. The parser copies an oversized PicturePath or ProfilePath value from ChaosPro.cfg into a fixed-size stack buffer, overwriting the SEH record. Execution requires a user to run ChaosPro with the malicious local configuration on Windows XP; the demonstrated payload starts a bind shell.
