How CVE-2025-4909 Works
This vulnerability exploits improper directory listing permissions in SourceCodester Client Database Management System 1.0, allowing remote attackers to access sensitive files without authentication. The system fails to restrict directory traversal, exposing configuration files, logs, and database backups. Attackers send crafted HTTP requests (e.g., GET /../../
) to enumerate directories. The flaw stems from missing access controls in Apache/NGINX configurations and insecure PHP file handling. CVSS 4.0 rates it 6.9 (MEDIUM) due to low attack complexity (AC:L) and network-based exploitation (AV:N). Public exploits leverage this to extract credentials or escalate privileges.
