VAR-201404-0541
Vulnerability from variot - Updated: 2025-09-21 23:04An attacker can exploit this vulnerability by copying an overly long NodeName2 argument into a statically sized buffer on the stack to overflow the static stack buffer. An attacker may use this vulnerability to remotely execute arbitrary code. 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 NodeName2 string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess fails to properly filter user input when processing odeName2 parameters, allowing remote attackers to exploit vulnerabilities to submit special parameters that trigger stack buffer overflows, causing applications to crash or execute arbitrary code. 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
