CVE-2007-6221 in TuMusika Evolution
Summary
by MITRE
TuMusika Evolution 1.7R5 allows remote attackers to obtain configuration information via a direct request to phpinfo.php, which calls the phpinfo function. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

This vulnerability exists in TuMusika Evolution 1.7R5, a web application that exposes sensitive configuration information through an insecure direct object reference flaw. The vulnerability stems from the presence of a phpinfo.php file that directly invokes the phpinfo() function without proper access controls or authentication mechanisms. This configuration allows any remote attacker to obtain detailed server configuration data including php settings, loaded extensions, environment variables, and potentially sensitive system information that could aid in further exploitation attempts.
The technical flaw represents a classic information disclosure vulnerability that aligns with CWE-200, which describes the exposure of sensitive information to an unauthorized actor. The phpinfo() function in php is designed for debugging and development purposes, providing comprehensive details about the php configuration, server environment, and loaded modules. When this function is accessible to unauthenticated users, it creates a significant security risk as attackers can gather intelligence about the underlying system architecture, php version, installed extensions, and potential vulnerabilities in the server configuration.
The operational impact of this vulnerability is substantial as it provides attackers with valuable reconnaissance data that can be used for subsequent attacks. The leaked configuration information may reveal database connection strings, file paths, server software versions, and other sensitive parameters that could be leveraged to exploit other vulnerabilities in the system. This information disclosure creates a foundation for privilege escalation, lateral movement, and targeted attacks against the application or underlying infrastructure. The vulnerability is particularly dangerous because it requires no authentication or specialized tools to exploit, making it an attractive target for automated scanning and exploitation.
From a threat modeling perspective, this vulnerability maps to several ATT&CK techniques including T1083 (File and Directory Discovery) and T1592 (Gather Victim Host Information) as attackers can systematically collect system information without requiring elevated privileges. The lack of access controls around the phpinfo.php endpoint demonstrates poor security practices in input validation and access control implementation. Organizations should implement proper authentication mechanisms, remove or secure development/debug files, and conduct regular security audits to identify and remediate similar vulnerabilities. The recommended mitigation includes removing the phpinfo.php file from production environments, implementing proper access controls, and ensuring that development tools are not accessible to unauthorized users.
The vulnerability highlights the importance of following security best practices such as the principle of least privilege and the secure configuration of web applications. Regular security assessments and penetration testing should be conducted to identify similar misconfigurations in web applications. Additionally, organizations should implement web application firewalls and monitoring solutions to detect and prevent unauthorized access attempts to sensitive configuration files. This vulnerability serves as a reminder that even seemingly benign development tools can pose significant security risks when improperly configured or exposed to unauthorized users.
