Summary
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 accept an unvalidated JSON option field, allowing arbitrary HAProxy directives to be injected into the configuration.
Risk Assessment
The risk involves the potential for remote code execution on the load balancer by an authenticated user, which could lead to serious security breaches within the organization's infrastructure.
Recommendation
It is recommended to upgrade to the latest version of Roxy-WI and implement additional input validation and verification mechanisms in the HAProxy configuration.
Other vulnerabilities in Roxy-WI
See all- CVE-2026-45556Critical
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the config_file_name field in the POST request /waf/<service>/<server_ip>/rule/<rule_id>/save is not properly validated, allowing an attacker to write files to any location on the load balancer's filesystem.
- CVE-2026-45552Critical
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the lack of proper decorators in certain endpoints allows any logged-in user, including the default guest role, to install and reconfigure exporters, WAF, and GeoIP databases on all servers in the Roxy-WI database.
- CVE-2026-45550Critical
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the PUT /smon/check functionality does not verify if the check_id belongs to the user's group, allowing unauthorized modifications to other users' monitoring settings.
- CVE-2026-45569High
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, there is a vulnerability that allows bypassing security checks related to path validation, potentially leading to path traversal attacks.
- CVE-2026-45567High
Roxy-WI, a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers, has an authentication bypass vulnerability in versions 8.2.6.4 and prior. This vulnerability allows bypassing authentication via the 'api' substring in the URL and accessing the unauthenticated /api/gpt.
- CVE-2026-45566Medium
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the login flow improperly handles URLs, allowing for an open redirect attack.
- CVE-2026-45565High
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the central Pydantic validator does not properly block metacharacters, allowing an attacker to inject unauthorized commands.
- CVE-2026-45564High
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the configver parameter in the URL path is interpolated without proper validation, leading to command injection vulnerabilities for authenticated users.
- CVE-2026-45563Medium
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the server_ip path parameter in GET /history/<service>/<server_ip> is reused as a user-id when service == 'user', with no authorization check.
- CVE-2026-45561Medium
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. In versions 8.2.6.4 and prior, the /smon/agent/{version,uptime,status,checks}/<server_ip> family of routes takes the URL path component verbatim, which may lead to unauthorized access.
Original NVD description (English source)
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.
