An exposed IOCTL with an  insufficient access control vulnerability has been identified in the utility, MxGeneralIo, for Moxa’s industrial x86 computers. The affected utility, MxGeneralIo, exposes IOCTL methods that permit direct read and write access to MSR and system memory. A local attacker with high privileges could abuse these interfaces to perform unauthorized operations. Successful exploitation may result in privilege escalation on Windows 7 systems or cause a system crash (BSoD) on Windows 10 and 11 systems, leading to a denial-of-service condition. The vulnerability could slightly affect the confidentiality and integrity of the device, but availability might be heavily impacted. No impact to the subsequent system has been identified.

Moxa Arm-based industrial computers running Moxa Industrial Linux Secure use a device-unique bootloader password provided on the device. An attacker with physical access to the device could use this information to access the bootloader menu via a serial interface.  Access to the bootloader menu does not allow full system takeover or privilege escalation. The bootloader enforces digital signature verification and only permits flashing of Moxa-signed images. As a result, an attacker cannot install malicious firmware or execute arbitrary code. The primary impact is limited to a potential temporary denial-of-service condition if a valid image is reflashed. Remote exploitation is not possible.

A physical attack vulnerability exists in certain Moxa industrial computers using TPM-backed LUKS full-disk encryption on Moxa Industrial Linux 3, where the discrete TPM is connected to the CPU via an SPI bus. Exploitation requires invasive physical access, including opening the device and attaching external equipment to the SPI bus to capture TPM communications. If successful, the captured data may allow offline decryption of eMMC contents. This attack cannot be performed through brief or opportunistic physical access and requires extended physical access, possession of the device, appropriate equipment, and sufficient time for signal capture and analysis. Remote exploitation is not possible.

This vulnerability is classified as Host Header Injection, where invalid Host headers can manipulate to redirect users, forge links, or phishing attacks. There is no impact to the confidentiality, integrity, and availability of the affected device; no loss of confidentiality, integrity, and availability within any subsequent systems.

Cross-site Scripting has been identified in Moxa’s Ethernet switches, which allows an authenticated administrative attacker to inject malicious scripts to an affected device’s web service that could impact authenticated users interacting with the device’s web interface. This vulnerability is classified as stored cross-site scripting (XSS); attackers inject malicious scripts into the system, and the scripts persist across sessions. There is no impact to the confidentiality, integrity, and availability of the affected device; no loss of availability within any subsequent systems but has some loss of confidentiality and integrity within the subsequent system.

An Use of Hard-coded Credentials vulnerability has been identified in Moxa’s network security appliances and routers. The system employs a hard-coded secret key to sign JSON Web Tokens (JWT) used for authentication. This insecure implementation allows an unauthenticated attacker to forge valid tokens, thereby bypassing authentication controls and impersonating any user. Exploitation of this vulnerability can result in complete system compromise, enabling unauthorized access, data theft, and full administrative control over the affected device. While successful exploitation can severely impact the confidentiality, integrity, and availability of the affected device itself, there is no loss of confidentiality or integrity within any subsequent systems.

An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A critical authorization flaw in the API allows an authenticated, low-privileged user to create a new administrator account, including accounts with usernames identical to existing users. In certain scenarios, this vulnerability could allow an attacker to gain full administrative control over the affected device, leading to potential account impersonation. While successful exploitation can severely impact the confidentiality, integrity, and availability of the affected device itself, there is no loss of confidentiality or integrity within any subsequent systems.

An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in the API authorization logic of the affected device allows an authenticated, low-privileged user to execute the administrative `ping` function, which is restricted to higher-privileged roles. This vulnerability enables the user to perform internal network reconnaissance, potentially discovering internal hosts or services that would otherwise be inaccessible. Repeated exploitation could lead to minor resource consumption. While the overall impact is limited, it may result in some loss of confidentiality and availability on the affected device. There is no impact on the integrity of the device, and the vulnerability does not affect any subsequent systems.

An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in broken access control has been identified in the /api/v1/setting/data endpoint of the affected device. This flaw allows a low-privileged authenticated user to call the API without the required permissions, thereby gaining the ability to access or modify system configuration data. Successful exploitation may lead to privilege escalation, allowing the attacker to access or modify sensitive system settings. While the overall impact is high, there is no loss of confidentiality or integrity within any subsequent systems.

An Incorrect Authorization vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in the API authentication mechanism allows unauthorized access to protected API endpoints, including those intended for administrative functions. This vulnerability can be exploited after a legitimate user has logged in, as the system fails to properly validate session context or privilege boundaries. An attacker may leverage this flaw to perform unauthorized privileged operations. While successful exploitation can severely impact the confidentiality, integrity, and availability of the affected device itself, there is no loss of confidentiality or integrity within any subsequent systems.
