ChurchCRM Installation Page Exposure Scanner

ChurchCRM is a widely used open-source church management software, designed to help religious organizations manage their operations efficiently. It is utilized by churches worldwide to maintain their membership databases, manage event scheduling, and communicate with congregants. The software offers a range of features including donation tracking, fund accounting, and member directories, making it an essential tool for church administrators. Administrators and volunteers typically operate ChurchCRM through a web interface, accessing it on desktops or mobile devices. Due to its comprehensive functionality and user-friendly interface, ChurchCRM is highly favored by small to medium-sized church communities.

The Installation Page Exposure vulnerability in ChurchCRM allows unauthorized users to access the setup wizard of ChurchCRM installations. This exposure occurs when the setup page remains publicly accessible post-installation, which could lead to serious security risks. Attackers who gain access to this page can attempt to install rogue versions of the software or manipulate configuration settings. Such exposure is often the result of misconfigured web server settings or failure to adequately secure the setup directory after initial installation. This vulnerability requires immediate attention to prevent unauthorized access and potential data breaches within the organization's CRM system. Regular security audits and adherence to best practices in securing web applications can significantly mitigate this risk.

The vulnerability occurs because the ChurchCRM setup wizard is accessible at a known URL endpoint, typically "BaseURL/setup". When this page is exposed to unauthorized users, it allows anyone to potentially rerun the setup process. The exposure is detectable by checking if the HTTP response status is 200 and if the page content includes strings such as "ChurchCRM setup wizard". If the setup page is accessible, it indicates that the setup process was not correctly completed or secured by the administrator. Mitigating this requires ensuring that setup scripts are removed or made inaccessible after the initial installation.

If exploited, this vulnerability could allow attackers to gain initial access to the CRM system, manipulate existing data, or install malicious copies of the application. The consequences can include unauthorized access to personal and financial data, leading to potential identity theft or financial fraud. Additionally, unauthorized installation of rogue modules may open backdoors, enabling further exploits or persistent threats within the system. Consequently, maintaining system integrity and data confidentiality becomes challenging, potentially damaging the organization's reputation and trust among its members.
