CVE-2026-27811

Estado: AnalizadaAlta (8.8)—

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to version 8.2.6.3, a command injection vulnerability exists in the `/config/compare/<service>/<server_ip>/show` endpoint, allowed authenticated users to execute arbitrary system commands on the app host. The vulnerability exists in `app/modules/config/config.py` on line 362, where user input is directly formatted in the template string that is eventually executed. Version 8.2.6.3 fixes the issue.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:L sin UI:R → T1210 (servicio remoto con privilegios). Command injection en endpoint autenticado permite ejecución arbitraria de comandos (T1059) y potencial escalada de privilegios en el host (T1068).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
