DescriptionCVE.org

AVS Audio Converter 9.1.2.600 contains a stack overflow vulnerability that allows attackers to execute arbitrary code by manipulating the output folder text input. Attackers can craft a malicious payload that overwrites stack memory and triggers a bind shell on port 9999 when the 'Browse' button is clicked.

Executive ViewAI

Why It Matters

AVS Audio Converter 9.1.2.600 contains a critical stack overflow vulnerability (CVE-2019-25318) that enables arbitrary code execution if users process untrusted files or interact with malicious folder paths. Any organization deploying this software faces immediate risk of compromise, particularly if the application processes user-supplied or external audio content.

Business Impact: High
Compensating Controls

Disable or uninstall AVS Audio Converter 9.1.2.600 immediately. If removal is not feasible: restrict application execution via application whitelisting/AppLocker policies; prevent end-user access to untrusted audio files; isolate affected systems from critical infrastructure using network segmentation; disable folder/file input dialogs where possible; monitor process execution logs for suspicious AVS behavior; consider containerization or sandbox execution to limit blast radius if exploitation occurs.

Attack Technique

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.
