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.

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.

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.

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.

An XXE vulnerability in LeviStudioU, Versions 1.8.29 and 1.8.44 can be exploited when the application processes specially crafted project XML files.

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.

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.

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 Technology Co., Ltd. PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior parse files and pass invalidated user data to an unsafe method call, which may allow code to be executed in the context of an administrator.

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 LeviStudio Versions 1.8.29 and 1.8.44 have multiple stack-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.
