CVE-2019-25318Public exploit

Code execution via oversized output-folder input

Published Feb 12, 2026 · Updated Feb 12, 2026

Stack-based buffer overflow in AVS Audio Converter 9.1.2.600 allows attackers to execute arbitrary code through the output-folder field. The output-folder text path accepts an oversized value and overwrites stack memory instead of enforcing the destination's bounds. Exploitation requires the crafted value to be present when the Browse button is clicked; the published demonstration opens a bind shell on TCP port 9999.
