Descriptions

When processing project files, the application (Omron CX-Programmer v9.70 and prior and Common Components January 2019 and prior) 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.

Al procesar archivos de proyecto, la aplicación (Omron CX-Programmer v9.70 y Common Components anteriores a enero de 2019) no comprueban si hacen referencia a la memoria liberada. Un atacante podría utilizar un archivo de proyecto especialmente diseñado para explotar y ejecutar código bajo los privilegios de la aplicación.

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 specific flaw exists within the parsing of CXP files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process.
