Descriptions

Out-of-bounds write vulnerability exists in CX-Programmer v.9.77 and earlier, which may lead to information disclosure and/or arbitrary code execution by having a user to open a specially crafted CXP file.

Existe una vulnerabilidad de escritura fuera de los límites en CX-Programmer v.9.77 y versiones anteriores, que puede provocar la divulgación de información y/o la ejecución de código arbitrario al pedirle a un usuario que abra un archivo CXP especialmente manipulado.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Omron CX-One. 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 in the CX-Programmer module. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
