CVE-2025-41652Network attack vector

Unauthenticated device compromise via forgeable MD5 hashes

Published May 27, 2025 · Updated Aug 22, 2025

Authentication bypass in Weidmüller industrial Ethernet switches allows remote attackers to gain administrative device access. The authorization mechanism uses MD5 authentication hashes that permit credential guessing or collision-based hash forgery. No account or user interaction is required; successful exploitation permits unauthorized control of switch data, configuration, and availability.
