CVE-2023-47407 is an information exposure vulnerability in Nagios XI affecting at least version 5.11.1. Sensitive files on the Nagios XI host were readable by all local users. Specifically, /usr/local/nagiosxi/html/config.inc.php contained plaintext database credentials and was world-readable, and /usr/local/nagiosxi/etc/htpasswd.users was also world-readable and exposed SHA1 password hashes for Nagios XI accounts. The issue is caused by overly permissive filesystem permissions on credential-bearing files, allowing unauthorized local users to read secrets that should be restricted to privileged service accounts or administrators.
