DESCRIPTION

Buffer overflow in Advantech WebAccess before 8.1_20160519 allows local users to cause a denial of service via a crafted DLL file. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in versions prior to Advantech WebAccess 8.1_20160519. An attacker could exploit this vulnerability to insert and execute arbitrary code with a specially crafted DLL file. Advantech WebAccess is prone to the following security vulnerabilities: 1. Unsafe ActiveX control local security vulnerability 2. A local buffer-overflow vulnerability Local attackers can exploit these issues to perform unauthorized actions and crash the affected application; denying service to legitimate users. Due to the nature of these issues, code-execution may be possible but this has not been confirmed
