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.

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.

A stack-based buffer overflow vulnerability has been found in the NPort W2150A-W4/W2250A-W4 Series version 1.5 and earlier. This vulnerability stems from insufficient input validation of user-supplied input in the "Server location" parameter on the Basic settings page. An attacker could exploit this vulnerability by sending crafted input to the web service, resulting in memory corruption. Successful exploitation of this vulnerability could allow remote code execution on the target system with root privileges.

A format string vulnerability has been found in the "alias" parameter of the Serial Param configuration page in the NPort W2150A-W4/W2250A-W4 Series version 1.5 and prior. This vulnerability stems from insufficient input validation and improper handling of externally supplied format strings. An attacker could exploit this vulnerability by sending crafted input to the web service, causing unintended memory disclosure. Successful exploitation may allow an attacker to leak sensitive memory contents and determine critical memory addresses, potentially bypassing Address Space Layout Randomization (ASLR) protections.

A denial-of-service vulnerability exists in NPort devices because of improper access control on the command port. The command interface does not properly validate whether a sender is associated with a valid data port session before accepting break signal commands. A remote attacker with network access can send crafted requests to disrupt serial communication for an active user session.

OnCell G3470A-LTE Series firmware versions v1.7.7 and prior have been identified as vulnerable due to a lack of neutralized inputs in the web key upload function. An attacker could modify the intended commands sent to target functions, which could cause malicious users to execute unauthorized commands.

OnCell G3470A-LTE Series firmware versions v1.7.7 and prior have been identified as vulnerable due to a lack of neutralized inputs in IPSec configuration. An attacker could modify the intended commands sent to target functions, which could cause malicious users to execute unauthorized commands.

OnCell G3470A-LTE Series firmware versions v1.7.7 and prior have been identified as vulnerable due to accepting a format string from an external source as an argument. An attacker could modify an externally controlled format string to cause a memory leak and denial of service.

OnCell G3470A-LTE Series firmware versions v1.7.7 and prior have been identified as vulnerable due to missing bounds checking on buffer operations. An attacker could write past the boundaries of allocated buffer regions in memory, causing a program crash.

TN-5900 Series version 3.3 and prior versions is vulnearble to user enumeration vulnerability. The vulnerability may allow a remote attacker to determine whether a user is valid during password recovery through the web login page and enable a brute force attack with valid users.

MXsecurity version 1.0 is vulnearble to command injection vulnerability. This vulnerability has been reported in the SSH CLI program, which can be exploited by attackers who have gained authorization privileges. The attackers can break out of the restricted shell and subsequently execute arbitrary code.

MXsecurity version 1.0 is vulnearble to hardcoded credential vulnerability. This vulnerability has been reported that can be exploited to craft arbitrary JWT tokens and subsequently bypass authentication for web-based APIs.
