TL;DR Moxa published advisory MPSA-269510 covering three Moxa vulnerabilities, all rated high severity. One affects the Remote Connect Suite (MRC Client), and two hit the end-of-life OnCell G3150A-LTE cellular gateway. MRC Client users can get a patch, but OnCell owners must rely on mitigations. Why It Matters Moxa equipment connects industrial sites, utilities and remote assets. The MRC Client sets up remote VPN links to those sites.
