Description

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.

How this vulnerability can be exploited

This issue can be reached from an adjacent network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity low, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N

  • Attack vector: Adjacent network — the attacker has to sit on the same local or logical network.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: None.

Weakness class

CVE-2026-32709 is classified as CWE-22: Path Traversal. A file path built from user input is not confined to the intended directory, letting an attacker reach files elsewhere on the filesystem.
