AI-analyzed exploit summary This exploit targets a SEH-based buffer overflow in VideoCharge Studio 2.12.3.685. It crafts a malicious .vsc file with a payload to execute arbitrary code (calc.exe) via a structured exception handler overwrite.

Description

A stack-based buffer overflow vulnerability exists in VideoCharge Studio 2.12.3.685 when processing a specially crafted .VSC configuration file. The issue occurs due to improper handling of user-supplied data in the XML 'Name' attribute, leading to an SEH overwrite condition. An attacker can exploit this vulnerability by convincing a user to open a malicious .VSC file, resulting in arbitrary code execution under the context of the user.
