Vulnerability from variot

A stack-based buffer overflow vulnerability in Advantech WebAccess Versions 9.02 and prior caused by a lack of proper validation of the length of user-supplied data may allow remote code execution. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the handling of IOCTL 0x2711, which can be used to invoke BwFLApp.exe. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a set of browser-based HMI/SCADA software from Advantech.

A stack buffer overflow vulnerability exists in Advantech WebAccess 9.02 and earlier. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment
