Descriptions

In Omron CX-Supervisor Versions 3.30 and prior, parsing malformed project files may cause a heap-based buffer overflow.

En las versiones 3.30 y anteriores de Omron CX-Supervisor, el análisis de archivos de proyecto mal formados puede provocar un desbordamiento de búfer basado en memoria dinámica (heap).

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OMRON CX-Supervisor. 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 processing of SCS project files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
