GE Fanuc CIMPLICITY HMI contains a remotely accessible heap buffer overflow vulnerability which may allow a remote attacker to execute arbitrary code.
GE Fanuc CIMPLICITY HMI is software used for monitoring and control in Supervisory Control And Data Acquisition (SCADA) systems. A heap buffer overflow vulnerability exists in a CIMPLICITY process (w32rtr.exe) that listens on the network (32000/tcp). The vulnerable process exists in both servers and clients. An attacker could exploit this vulnerability by sending a specially crafted packet to a vulnerable CIMPLICITY system.
Note that this vulnerability affects GE Fanuc CIMPLICITY HMI versions up to and including version 7.0.
A remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial of service.
This vulnerability was reported by Eyal Udassin of C4 Security.
