Vulnerabilities & Exploits

Mitsubishi Electric flaws span code execution and access bypass

CISA lists four vulnerabilities affecting ten Mitsubishi Electric software suites, with outcomes ranging from arbitrary code execution to authentication bypass and denial of service.

CVE-2023-4863 can enable arbitrary code execution in GENESIS64 and ICONICS Suite versions 10.97 through 10.97.2. The other three flaws affect product-specific subsets: two can let an attacker bypass authentication, while another permits arbitrary operations. CISA says exploitation could expose, alter, destroy, or delete information, or make a system unavailable.

CISA identifies critical manufacturing as a sector where these products are deployed worldwide. Its excerpt names version 10.97.3 or later for GENESIS64 and ICONICS Suite, but does not map fixes across the rest of the affected products. A plant using another listed suite therefore cannot infer its remediation status from that version alone.
