CVE-2026-45558— Roxy-WI 输入验证错误漏洞

Roxy-WI: Authenticated RCE on every managed HAProxy load balancer via `option` field config injection in section save

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the HAProxy section-save endpoints (POST /api/service/haproxy/<server_id>/section/<section_type> and the PUT / global / defaults variants) accept a JSON option field that is not validated, not escaped, and is rendered verbatim into the generated HAProxy configuration via the section.j2, global.j2, and defaults.j2 Ansible templates. Because Roxy-WI then pushes the generated config to the load balancer and runs systemctl reload haproxy, an authenticated user with role ≤ 3 (user) can inject arbitrary HAProxy directives into the config that runs on every load balancer their group manages — including option external-check + external-check command /bin/bash -c '…', which gives remote code execution on the load balancer as the haproxy user on every health-check tick. At time of publication, there are no publicly available patches.

输入验证不恰当

Roxy-WI 输入验证错误漏洞

Roxy-WI是Roxy-WI开源的一款用于管理 Haproxy、Nginx 和 Keepalived 服务器的 Web 界面。 Roxy-WI 8.2.6.4及之前版本存在输入验证错误漏洞，该漏洞源于HAProxy部分保存端点接受未验证、未转义的JSON选项字段并直接渲染到生成的HAProxy配置中，认证用户可注入任意HAProxy指令导致远程代码执行。
