Magix Musik Maker 16 Stack-Based Buffer Overflow Vulnerability Allowing Arbitrary Code Execution

A stack-based buffer overflow vulnerability has been identified in Magix Musik Maker 16, all versions through 16.0.2.4. This issue arises from improper handling of .mmm arrangement files, where an unsafe strcpy() operation fails to validate input length. Attackers can exploit this vulnerability by crafting a malicious .mmm file that, when opened, overwrites the Structured Exception Handler (SEH). This exploitation bypasses Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR), potentially leading to arbitrary code execution.

Impact

Exploitation of this vulnerability allows for a stack-based buffer overflow, overwriting the Structured Exception Handler and leading to arbitrary code execution.

Reproduction

To reproduce this vulnerability, create a .mmm file that includes a payload designed to exploit the buffer overflow. The payload should be crafted to overwrite the Structured Exception Handler. Once the file is prepared, open it in Magix Musik Maker 16. The application will process the file, triggering the buffer overflow and executing the embedded payload.

Remediation

Users can upgrade to Magix Musik Maker version 17 or later to address this vulnerability.
