VAR-202511-0448

Vulnerability from variot - Updated: 2025-12-20 19:39

Advantech WebAccess/VPN versions prior to 1.1.5 contain a stored cross-site scripting (XSS) vulnerability via StandaloneVpnClientsController.addStandaloneVpnClientAction(). Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser. 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. This vulnerability stems from insufficient validation of user input in the StandaloneVpnClientsController.addStandaloneVpnClientAction function
