CVE-2026-9266
A Missing Required Cryptographic Step vulnerability has been identified in Moxa's embedded Linux firmware for industrial computers and controllers.
Overview
CVE-2026-9266 is a known-severity vulnerability. It was published on June 12, 2026.
Technical description
A Missing Required Cryptographic Step vulnerability has been identified in Moxa's embedded Linux firmware for industrial computers and controllers. This vulnerability represents an incomplete remediation of CVE-2026-0714. The firmware introduced TPM2 parameter encryption as a countermeasure against CVE-2026-0714. However, an omission in the authorization session configuration causes the parameter encryption to provide no effective protection. An attacker with invasive physical access to the device can still capture TPM communications on the SPI bus and derive the LUKS disk encryption key in plaintext. While successful exploitation results in full compromise of the encrypted disk volume, the attack requires invasive physical access, including opening the device and attaching external equipment to the SPI bus. Remote exploitation is not possible, and the attack does not affect any downstream systems.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-9266?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-9266 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
