VULNERABILITY DETAILS	This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Schneider Electric ProClima. 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 ATX45.ATX45Ctrl.1 ActiveX control in Atx45.ocx. The control does not check the length of an attacker-supplied string in the SetHtmlFileName method before copying it into a fixed length buffer on the heap. This allows an attacker to execute arbitrary code in the context of the browser process.
