Authored by Tipping Point | Site zerodayinitiative.com

Zero Day Initiative Advisory 12-169 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of GE Proficy Historian. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the KeyHelp.ocx ActiveX control. The control contains a LaunchTriPane function that allows launching of the HTML Help executable (hh.exe) with customized command line parameters. By using the -decompile switch, an attacker can specify the folder to decompile to and a UNC path to a specially crafted .chm file. The attacker can utilize this vulnerability to execute remote code under the context of the process.
