Executive Summary

This vulnerability exists in IPFire 2.21 Core Update 127 within the ovpnmain.cgi script. It involves multiple cross-site scripting (XSS) flaws that allow attackers to inject malicious scripts through various VPN configuration parameters.

Attackers can send POST requests containing script payloads in parameters such as VPN_IP, DMTU, ccdname, ccdsubnet, DOVPN_SUBNET, DHCP_DOMAIN, DHCP_DNS, DHCP_WINS, ROUTES_PUSH, FRAGMENT, KEEPALIVE_1, and KEEPALIVE_2. This enables them to execute arbitrary JavaScript code in the browsers of administrators who access the affected interface.

Impact Analysis

The vulnerability can lead to the execution of arbitrary JavaScript in administrator browsers, potentially allowing attackers to hijack administrator sessions, steal sensitive information, or perform unauthorized actions within the administrative interface.

Since the attack targets administrator browsers, it can compromise the security and integrity of the VPN configuration and management, leading to further exploitation or disruption of network security.
