CVE-2024-44820Network attack vector

Unauthenticated PHP environment disclosure via phpinfo trigger

Published Sep 4, 2024 · Updated Sep 4, 2024

Information disclosure in ZZCMS 2023 and earlier allows remote attackers to read PHP environment details through eginfo.php. The /3/E_bak5.1/upload/eginfo.php handler invokes phpinfo() when the phome query parameter equals ShowPHPInfo, without an authorization check. No authentication is required, and the response exposes server configuration, loaded modules, and environment variables without granting data modification or service interruption.
