VAR-202511-1878

Vulnerability from variot - Updated: 2025-12-20 23:40

Advantech WebAccess/VPN versions prior to 1.1.5 contain a SQL injection vulnerability in AjaxDeviceController.ajaxDeviceAction() 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 AjaxDeviceController.ajaxDeviceAction function's failure to properly filter datatable search parameters. Attackers can exploit this vulnerability to execute illegal SQL commands and steal sensitive database data
