TITLE

Advantech WebAccess/VPN AjaxFwRulesController.ajaxDeviceFwRulesAction function SQL injection vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-31067

DESCRIPTION

Advantech WebAccess/VPN versions prior to 1.1.5 contain a SQL injection vulnerability in AjaxFwRulesController.ajaxDeviceFwRulesAction() 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 secure and reliable network connectivity solutions for industrial automation and remote monitoring systems. Advantech WebAccess/VPN contains an SQL injection vulnerability. This vulnerability stems from the fact that the `AjaxFwRulesController.ajaxDeviceFwRulesAction` function does not adequately validate the datatable search parameters. Attackers can exploit this vulnerability to execute illegal SQL commands and steal sensitive database data
