Descriptions

In Omron CX-Supervisor Versions 3.30 and prior, parsing malformed project files may cause an out of bounds vulnerability.

En las versiones 3.30 y anteriores de Omron CX-Supervisor, el análisis de archivos de proyecto mal formados puede provocar una vulnerabilidad fuera de límites.

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 parsing of SCS project files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
