TITLE

Omron CX-One Memory Error Reference Vulnerability

Trust: 0.8

sources: IVD: 7d806040-463f-11e9-aaa9-000c29342cb1 // CNVD: CNVD-2018-25309

DESCRIPTION

In CX-One Versions 4.42 and prior (CX-Programmer Versions 9.66 and prior and CX-Server Versions 5.0.23 and prior), when processing project files, the application fails to check if it is referencing freed memory. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OMRON CX-One CX-Programmer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The issue results from the lack of validating the existence of an object prior to performing operations on the object. The Omron CX-One is an integrated toolkit from Omron, Japan (Omron) that includes networking, PT, frequency converters, temperature controllers, and PLC programming software. CX-Programmer is one of the PLC programming software. CX-Server is one of the driver management tools. A memory error reference vulnerability exists in Omron CX-One 4.42 and earlier (CX-Programmer 9.66 and earlier and CX-Server 5.0.23 and earlier). The vulnerability stems from a failure to check if the program is processing a project file. Reference the memory that was released. Omron CX-One is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2
