TITLE

Advantech WebAccess Unspecified ActiveX Vulnerabilities that capture important information in controls

Trust: 0.8

sources: JVNDB: JVNDB-2016-003355

DESCRIPTION

Unspecified ActiveX controls in Advantech WebAccess before 8.1_20160519 allow remote authenticated users to obtain sensitive information or modify data via unknown vectors, related to the INTERFACESAFE_FOR_UNTRUSTED_CALLER (aka safe for scripting) flag. 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. An arbitrary code execution vulnerability exists in Advantech WebAccess prior to 8.1_20160519, which was caused by a program that marked an unsafe ActiveX control as safe-for-scripting. An attacker could exploit this vulnerability to insert and execute arbitrary code. Advantech WebAccess is prone to the following security vulnerabilities: 1. 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. Versions prior to Advantech WebAccess 8.1_20160519 are vulnerable
