CVE-2023-32652Network attack vector

Script execution via unvalidated identification strings

Published Jul 6, 2023 · Updated Nov 13, 2024

Cross-site scripting in PiiGAB M-Bus SoftwarePack 900S allows remote authenticated users to execute script through identification strings. The affected processing path fails to validate attacker-controlled identification values before they reach a browser context. A low-privileged account and interaction by another user are required; CISA does not disclose the exact injection endpoint or resulting browser actions.
