PHP source disclosure via webserver misconfiguration

Published Nov 18, 2025 · Updated Nov 18, 2025

Information disclosure in METZ CONNECT EWIO2 firmware before 2.2.0 allows remote attackers to read PHP module source over the network. The web server misconfiguration serves requested PHP module files as source text instead of executing them or denying direct access. No credentials or user interaction are required; the reported impact is limited to confidentiality, with no write or service-interruption capability.
