      "value": "PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, An unauthenticated path traversal vulnerability in the PX4 Autopilot MAVLink FTP implementation allows any MAVLink peer to read, write, create, delete, and rename arbitrary files on the flight controller filesystem without authentication. On NuttX targets, the FTP root directory is an empty string, meaning attacker-supplied paths are passed directly to filesystem syscalls with no prefix or sanitization for read operations. On POSIX targets (Linux companion computers, SITL), the write-path validation function unconditionally returns true, providing no protection. A TOCTOU race condition in the write validation on NuttX further allows bypassing the only existing guard. This vulnerability is fixed in 1.17.0-rc2."

Antes de la versi\u00f3n 1.17.0-rc2, una vulnerabilidad de salto de ruta no autenticado en la implementaci\u00f3n FTP MAVLink del piloto autom\u00e1tico PX4 permite a cualquier par MAVLink leer, escribir, crear, eliminar y renombrar archivos arbitrarios en el sistema de archivos del controlador de vuelo sin autenticaci\u00f3n. En objetivos NuttX, el directorio ra\u00edz FTP es una cadena vac\u00eda, lo que significa que las rutas proporcionadas por el atacante se pasan directamente a las llamadas al sistema del sistema de archivos sin prefijo ni saneamiento para operaciones de lectura. En objetivos POSIX (ordenadores compa\u00f1eros Linux, SITL), la funci\u00f3n de validaci\u00f3n de ruta de escritura devuelve \u0027true\u0027 incondicionalmente, no proporcionando ninguna protecci\u00f3n. Una condici\u00f3n de carrera TOCTOU en la validaci\u00f3n de escritura en NuttX permite adem\u00e1s eludir la \u00fanica protecci\u00f3n existente.
