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

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
