CVE-2024-12142Network attack vector

Unauthenticated page disclosure, modification, and service interruption

Published Jan 17, 2025 · Updated Feb 12, 2025

Information exposure in Schneider Electric Modicon M340 device web servers allows remote attackers to disclose or alter pages and interrupt service. Schneider Electric has not published the affected page names or the faulty operation that permits unauthorized modification and invocation of restricted functions. Network access to an enabled web server is sufficient; exploitation can expose restricted content, alter a page, and interrupt device availability.
