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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less
