Vulnerabilities

WECON LeviStudioU Versions 2019-09-21 and prior are vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute code.

WECON LeviStudioU Versions 2019-09-21 and prior are vulnerable to multiple stack-based buffer overflow instances while parsing project files, which may allow an attacker to execute arbitrary code.

PLC Editor Versions 1.3.8 and prior is vulnerable to a stack-based buffer overflow while processing project files, which may allow an attacker to execute arbitrary code.

Multiple buffer overflow vulnerabilities exist when LeviStudioU (Version 2019-09-21 and prior) processes project files. Opening a specially crafted project file could allow an attacker to exploit and execute code under the privileges of the application.

A heap-based buffer overflow vulnerability exists within the WECON LeviStudioU Release Build 2019-09-21 and prior when processing project files. Opening a specially crafted project file could allow an attacker to exploit and execute code under the privileges of the application.

WECON PLC Editor Versions 1.3.8 and prior has a heap-based buffer overflow vulnerabilities have been identified that may allow arbitrary code execution.

An XXE vulnerability exists within LeviStudioU Release Build 2019-09-21 and prior when processing parameter entities, which may allow file disclosure.

Multiple buffer overflow vulnerabilities exist when the PLC Editor Version 1.3.5_20190129 processes project files. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.

WECON Technology PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior lacks proper validation of user-supplied data, which may result in a read past the end of an allocated object.

Several heap-based buffer overflow vulnerabilities in WECON LeviStudioU version 1.8.56 and prior have been identified, which may allow arbitrary code execution. Mat Powell, Ziad Badawi, and Natnael Samson working with Trend Micro's Zero Day Initiative, reported these vulnerabilities to NCCIC.

An out-of-bounds vulnerability in LeviStudioU, Versions 1.8.29 and 1.8.44 can be exploited when the application processes specially crafted project files.

WECON Technology Co., Ltd. PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior have a stack-based buffer overflow vulnerability which may allow remote code execution.

WECON LeviStudio Versions 1.8.29 and 1.8.44 have multiple heap-based buffer overflow vulnerabilities that can be exploited when the application processes specially crafted project files.

WECON PLC Editor version 1.3.3U may allow an attacker to execute code under the current process when processing project files.

A buffer overflow can be triggered in LeviStudio HMI Editor, Version 1.10 part of Wecon LeviStudioU 1.8.29, and PI Studio HMI Project Programmer, Build: November 11, 2017 and prior by opening a specially crafted file.

An issue was discovered in WECON Technology LEVI Studio HMI Editor v1.8.29 and prior. Specially-crafted malicious files may be able to cause stack-based buffer overflow vulnerabilities, which may allow remote code execution.

A Heap-based Buffer Overflow issue was discovered in WECON LeviStudio HMI. The heap-based buffer overflow vulnerability has been identified, which may allow remote code execution.

A Stack-based Buffer Overflow issue was discovered in WECON LEVI Studio HMI Editor v1.8.1 and prior. Multiple stack-based buffer overflow vulnerabilities have been identified in which the application does not verify string size before copying to memory; the attacker may then be able to crash the application or run arbitrary code.

A Heap-Based Buffer Overflow issue was discovered in Wecon Technologies LEVI Studio HMI Editor before 1.8.1. This vulnerability causes a buffer overflow when a maliciously crafted project file is run by the system.
