Vulnerability Title
OpenWrt odhcpd/LuCI: unauthenticated DHCPv6 client can inject lease-file lines via FQDN hostname → stored XSS in the LuCI admin UI
Vulnerability Description
OpenWrt is a Linux operating system targeting embedded devices. Prior to 25.12.5, odhcpd writes a DHCPv6 client FQDN option 39 hostname into /tmp/odhcpd.leases through src/statefiles.c statefiles_write_state6() and statefiles_write_state4() without escaping, allowing newline injection of forged lease lines that LuCI rpcd-mod-luci getDHCPLeases displays through htdocs/luci-static/resources/view/status/include/40_dhcp.js and htdocs/luci-static/resources/luci.js dom.append as live HTML in the Active DHCPv6 Leases admin page. This vulnerability is fixed in 25.12.5.

Vulnerability Title
OpenWrt 输出处理不当漏洞
Vulnerability Description
OpenWrt是OpenWRT社区开源的一套针对嵌入式设备的Linux操作系统。 OpenWrt 25.12.5之前版本存在安全漏洞,该漏洞源于odhcpd在将DHCPv6客户端FQDN选项39的主机名写入/tmp/odhcpd.leases时未进行转义,导致可在管理员页面的Active DHCPv6 Leases中注入伪造的租赁行,从而造成跨站脚本攻击。
