Vulnerability from variot - Updated: 2025-12-20 23:37

Advantech WebAccess/VPN versions prior to 1.1.5 contain a SQL injection vulnerability in AjaxFwRulesController.ajaxNetworkFwRulesAction() that allows an authenticated low-privileged observer user to inject SQL via datatable search parameters, leading to disclosure of database information. Advantech WebAccess/VPN is a virtual private network function integrated into Advantech's WebAccess/SCADA software, designed to provide a secure and reliable network connectivity solution for industrial automation and remote monitoring systems.

Advantech WebAccess/VPN contains an SQL injection vulnerability. This vulnerability stems from improper handling of datatable search parameters in the AjaxFwRulesController.ajaxNetworkFwRulesAction function. Attackers can exploit this vulnerability to execute illegal SQL commands and steal sensitive database data

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.
