CVE-2025-54386

Traefik is an HTTP reverse proxy and load balancer. In versions 2.11.27 and below, 3.0.0 through 3.4.4 and 3.5.0-rc1, a path traversal vulnerability was discovered in WASM Traefik’s plugin installation mechanism. By supplying a maliciously crafted ZIP archive containing file paths with ../ sequences, an attacker can overwrite arbitrary files on the system outside of the intended plugin directory. This can lead to remote code execution (RCE), privilege escalation, persistence, or denial of service. This is fixed in versions 2.11.28, 3.4.5 and 3.5.0.

Summary		(es) Traefik es un proxy inverso HTTP y balanceador de carga. En las versiones 2.11.27 y anteriores, 3.0.0 a 3.4.4 y 3.5.0-rc1, se descubrió una vulnerabilidad de Path traversal en el mecanismo de instalación del complemento de WASM Traefik. Al proporcionar un archivo ZIP manipulado con fines malintencionados que contiene rutas de archivos con secuencias ../, un atacante puede sobrescribir archivos arbitrarios en el sistema fuera del directorio del complemento. Esto puede provocar ejecución remota de código (RCE), escalada de privilegios, persistencia o denegación de servicio. Esto se ha corregido en las versiones 2.11.28, 3.4.5 y 3.5.0.
