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 Stack-Based Buffer Overflow issue was discovered in Wecon Technologies LEVI Studio HMI Editor before 1.8.1. This vulnerability causes a buffer overflow, which could result in denial of service when a malicious project file is run on the system.

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.

WECON LeviStudioU

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

WECON LeviStudioU

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.

WECON PLC Editor

PLC Editor Versions 1.3.8 and prior is vulnerable to an out-of-bounds write while processing project files, which may allow an attacker to execute arbitrary code.

WECON PLC Editor

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.

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.

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

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.

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

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 memory corruption vulnerability has been identified in WECON LeviStudioU version 1.8.56 and prior, 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.

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.

Multiple stack-based buffer overflow vulnerabilities in WECON LeviStudioU version 1.8.56 and prior may be exploited when parsing strings within project files. The process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage these vulnerabilities to execute code under the context of the current process. Mat Powell, Ziad Badawi, and Natnael Samson working with Trend Micro's Zero Day Initiative, reported these vulnerabilities to NCCIC.

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.

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.

In WECON Technology Co., Ltd. PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior when parsing project files, the XMLParser that ships with Wecon PIStudio is vulnerable to a XML external entity injection attack, which may allow sensitive information disclosure.
