CVE-2025-14282

Estado: AplazadaMedia (5.4)—

A flaw was found in Dropbear. When running in multi-user mode and authenticating users, the dropbear ssh server does the socket forwardings requested by the remote client as root, only switching to the logged-in user upon spawning a shell or performing some operations like reading the user's files. With the recent ability of also using unix domain sockets as the forwarding destination any user able to log in via ssh can connect to any unix socket with the root's credentials, bypassing both file system restrictions and any SO_PEERCRED / SO_PASSCRED checks performed by the peer.

Cuando se ejecuta en modo multiusuario y autentica usuarios, el servidor ssh dropbear realiza los reenvíos de sockets solicitados por el cliente remoto como root, cambiando al usuario autenticado solo al generar un shell o al realizar algunas operaciones como leer los archivos del usuario. Con la capacidad reciente de también usar sockets de dominio unix como destino de reenvío, cualquier usuario capaz de iniciar sesión a través de ssh puede conectarse a cualquier socket unix con las credenciales de root, eludiendo tanto las restricciones del sistema de archivos como cualquier verificación SO_PEERCRED / SO_PASSCRED realizada por el par."
