This could allow an attacker with physical access to the product to upload arbitrary malicious firmware to the device without authentication. View CVE Details Affected Products CubeSpace CW0057 Reaction Wheel Vendor: CubeSpace Product Version: CubeSpace CW0057 Reaction Wheel: <firmware_5.0.20 Product Status: known_affected Remediations Vendor fix CubeSpace has released the following firmware versions for users to enable: Firmware version 5.0.20. Firmware version 5.0.20 introduces the capability for cryptographically verified secure boot; however, this protection is not enabled by default. Users must activate signed‑boot functionality, particularly the fully immutable mode, to achieve full security. Mitigation CubeSpace acknowledges the finding. The CW0057 reaction wheel authenticates firmware updates with a CRC-32 integrity check, which confirms image integrity but does not verify the source of an image. Exploitation requires direct physical access to the device and is not exploitable remotely. A device affected by this method remains recoverable: the bootloader operates independently of the application firmware and can reload known-good, CubeSpace-supplied images, so an affected unit cannot be permanently disabled by this method. Starting with firmware version 5.0.20, Cube
