VAR-202002-1366

Vulnerability from variot - Updated: 2024-11-23 23:01

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Moxa MGate 5105-MB-EIP firmware version 4.1. Authentication is required to exploit this vulnerability. The specific flaw exists within the DestIP parameter within MainPing.asp. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9552. Moxa MGate 5105-MB-EIP For firmware, OS A command injection vulnerability exists. Zero Day Initiative To this vulnerability ZDI-CAN-9552 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. MGate 5105-MB-EIP is an industrial Ethernet gateway that supports MQTT or third-party cloud services (such as Azure and Alibaba Cloud). It can construct Modbus RTU/ASCII/TCP and EtherNet/IP network communications for IIoT applications
