CRITICAL 9.8

DescriptionCVE.org

WMV to AVI MPEG DVD WMV Convertor 4.6.1217 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting the license name and license code fields. Attackers can craft a malicious payload of 6000 bytes to trigger a bind shell on port 4444 by exploiting a stack-based buffer overflow in the application's input handling.

Executive ViewAI

Why It Matters

A critical vulnerability in WMV to AVI/MPEG/DVD converter software (versions up to 4.6.1217) allows attackers to execute arbitrary code with a CVSS score of 9.8. Organizations using this software are at immediate risk of system compromise, data theft, and operational disruption, particularly if the application processes untrusted media files from external sources.

Business Impact: Severe

Compensating Controls

Disable or uninstall the vulnerable software immediately if not critical to operations. If retention is required: restrict application usage to isolated, air-gapped systems; implement strict file-based access controls limiting which users can execute the converter; disable network access from the application layer; monitor process execution and file system changes for suspicious activity; apply application whitelisting to prevent execution of unknown binaries created by the converter.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Stack-based Buffer Overflow HIGH

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.
