Descriptions

In Omron CX-Supervisor Versions 3.30 and prior, processing a malformed packet by a certain executable may cause an untrusted pointer dereference vulnerability.

En las versiones 3.30 y anteriores de Omron CX-Supervisor, el procesamiento de un paquete mal formado por parte de cierto ejecutable puede provocar una vulnerabilidad de desreferencia de puntero no fiable.

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 CDM file. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code under the context of the current process.
