CVE-2025-34081Network attack vector

Information disclosure via exposed phpinfo debug page

Published Jul 1, 2025 · Updated Nov 21, 2025

Information disclosure in CONTEC CONPROSYS HMI System (CHS) before 3.7.7 allows remote attackers to read PHP runtime data. An unauthenticated PHP phpinfo() debug page returns runtime configuration details that the application does not need to publish. Network reachability alone is sufficient, and the returned details can expose configuration and environment data useful for follow-on attacks.
