View CSAF Summary Successful exploitation of this vulnerability could allow an attacker to upload arbitrary malicious firmware to the device. The following versions of CubeSpace CW0057 Reaction Wheel are affected: CW0057 Reaction Wheel CVSS Vendor Equipment Vulnerabilities v3 6.1 CubeSpace CubeSpace CW0057 Reaction Wheel Improper Verification of Cryptographic Signature Background Critical Infrastructure Sectors: Communications Countries/Areas Deployed: Worldwide Company Headquarters Location: South Africa Vulnerabilities Expand All + CVE-2026-13743 CubeSpace CW0057 Reaction Wheel firmware versions prior to 5.0.20 are vulnerable to an Improper Verification of Cryptographic Signature vulnerability. 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, CubeSpace offers optional cryptographic secure boot of varying security levels which customers can enable. Given the physical-access prerequisite and the availability of recovery, CubeSpace assesses the practical risk as low.

Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly availab
