IPFire 2.21 Core Update 127 contains multiple cross-site scripting vulnerabilities in the ovpnmain.cgi script that allow attackers to inject malicious scripts through VPN configuration parameters. Attackers can submit POST requests with script payloads in parameters like VPN_IP, DMTU, ccdname, ccdsubnet, DOVPN_SUBNET, DHCP_DOMAIN, DHCP_DNS, DHCP_WINS, ROUTES_PUSH, FRAGMENT, KEEPALIVE_1, and KEEPALIVE_2 to execute arbitrary JavaScript in administrator browsers.
