Bugzilla Config Exposure Scanner

Bugzilla is an open-source issue tracking system widely used by organizations to track and manage software development projects. It is often employed by developers, project managers, and testers to facilitate collaboration and maintain records of reported and fixed bugs. Bugzilla is used across various industries, ensuring efficient bug tracking and resolution through its web-based interface. The system can be installed on a server and accessed via a web browser, making it a flexible solution for distributed teams. Due to its open-source nature, Bugzilla can be customized and extended with additional features. Proper configuration and security measures are crucial to protect Bugzilla installations from vulnerabilities.

This vulnerability allows unauthorized access to configuration files on a Bugzilla server. An improperly protected 'config.cgi' file exposes critical information, such as domain and user details, to potential attackers. Public exposure of this configuration file could lead to unauthorized information disclosure and compromise. By detecting this exposure, security teams can take measures to safeguard sensitive server information. Ensuring proper access controls and restricting exposure of configuration files is essential to prevent exploitation. Regular security audits and monitoring can aid in early detection and remediation of such vulnerabilities.

The vulnerability lies in the unprotected exposure of the 'config.cgi' file on the server. Attackers can access this file using a GET request to enumerate information about the main domain and registered users. The scanner checks for a status code of 200, indicating successful access to the file, and looks for specific content such as "base_url" and "maintainer". Proper content type matching is also observed to ensure the exposed file is a configuration file. Regular checks and updates are vital to prevent this misconfiguration from leading to information exposure.

Exploiting this vulnerability can lead to leakage of sensitive server configuration details. Malicious actors could utilize such information to craft targeted attacks against the server and its users. Unauthorized access to user data might result in account compromise or spear-phishing attacks. Exposure can also provide insights into server infrastructure, enabling attackers to plan more sophisticated exploitation strategies. Safeguarding configuration files is crucial to maintaining the overall security posture of Bugzilla installations.
