| Beschreibung | Authenticated web admin can achieve root execution via /sbin/rc start_vpnserver (0x434DFC), two paths: (1) CWE-78: vpn_server%d_proto embedded via fprintf into #!/bin/sh script /etc/openvpn/fw/server%d-fw.sh, newline injection, executed via _eval; (2) CWE-74: vpn_server%d_custom written via fputs into OpenVPN config.ovpn (e.g. script-security 2, up directive).
CVSS 3.1: AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H = 7.2 HIGH. Dynamic PoC: /tmp/pwned_vpnserver created for chain 1.
Advisory: https://gitee.com/WH-YHUST/tomato-rc-nvram-cve/blob/master/gitee-cve-disclosure/advisories/en/03-start_vpnserver.md
Fix: whitelist proto; no shell scripts; block dangerous OpenVPN directives in custom config. |
