CVE-2025-27452Network attack vector

Unauthenticated information disclosure via enabled directory indexes

Published Jul 3, 2025 · Updated Jul 3, 2025

Directory listing in the Apache httpd server for Endress+Hauser MEAC300-FNADE4 0 through 0.16.0 allows remote attackers to read exposed file names. Unnecessary enabled Apache modules allow directory indexes to be generated for web paths that lack an index document. No authentication or user interaction is required; disclosed directory contents can reveal files and paths, but no write or service-interruption impact is reported.
