TITLE

Advantech WebAccess Vulnerable to stack-based buffer overflow

Trust: 0.8

sources: JVNDB: JVNDB-2014-001980

DESCRIPTION

Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long UserName parameter. 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 webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied UserName string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions
