CVE-2024-1532Network attack vector

Diagnostic display disruption via crafted language file

Published Mar 27, 2024 · Updated Aug 1, 2024

Unrestricted file upload in Hitachi Energy RTU500 Series CMU Firmware allows remote authenticated users to suppress diagnostic text. The stb-language file handler processes a specially crafted uploaded language file and replaces diagnostic text with empty strings. Access requires an authorized account with file-upload capability; exploitation degrades diagnostic visibility without reported confidentiality or integrity effects.
