VAR-201404-0541

Vulnerability from variot - Updated: 2023-12-18 12:51

Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long NodeName2 argument. 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 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

    "data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long NodeName2 argument. 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 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. \nAdvantech 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",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
