SuperNote A6 X2 Nomad: Relative Path Traversal

CVE-2025-32409 is a high-severity relative path traversal vulnerability in SuperNote A6 X2 Nomad from Ratta, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version December 2024 as the first without the flaw, so updating SuperNote A6 X2 Nomad to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.13% chance of exploitation within 30 days, higher than 67% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update SuperNote A6 X2 Nomad to December 2024 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Ratta SuperNote A6 X2 Nomad before December 2024 allows remote code execution because an arbitrary firmware image (signed with debug keys) can be sent to TCP port 60002, and placed into the correct image-update location as a consequence of both directory traversal and unintended handling of concurrency.

The underlying weakness: Relative Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.

How developers prevent this class of flaw

  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
