CouchDB Configuration File Disclosure Scanner

CouchDB is a database software that is widely used in applications requiring data storage and retrieval. It is utilized by developers and organizations to manage large volumes of data through its NoSQL database architecture. Popular for its ease of use and flexibility, CouchDB supports a variety of platforms including cloud and on-premise environments. It is generally used in analytics, real-time applications, and other data-intensive projects. Developers appreciate its schema-free design, which allows them to work with complex data types. CouchDB's replication features make it ideal for distributed computing applications.

The unauthorized admin access vulnerability in CouchDB allows attackers to gain unauthorized access to the database with administrative privileges. This vulnerability arises when the default 'admin party' mode is left enabled, allowing anyone to perform admin actions without proper authentication. Attackers can exploit this vulnerability to read sensitive data, manipulate database structs, or disrupt operations. It is a significant security gap as it circumvents the authentication mechanisms protecting the database. Due to its default configuration, CouchDB installations are often susceptible if not properly secured. Ensuring proper authentication is crucial to preventing unauthorized access.

The vulnerability is detailed in the HTTP GET method targeting the {{BaseURL}}/_users/_all_docs endpoint. In the scenario where CouchDB is configured with default settings, the attacker does not require credentials to access administrative functions. The template checks the response headers for the presence of CouchDB and Erlang OTP, indicating that it is susceptible. Furthermore, it matches the body contents for terms like 'total_rows' and 'offset', confirming the possibility of improper access. The main issue lies in misconfigured authentication settings, allowing open access to sensitive database functions.

Exploitation of this vulnerability could lead to severe consequences including unauthorized data access and manipulation. Malicious actors may exfiltrate sensitive information, alter or delete important records, and potentially shut down database operations. In worst-case scenarios, it could lead to data breaches impacting privacy and regulatory compliance, resulting in financial and reputational damages. It is imperative to address this vulnerability to safeguard database integrity and confidentiality.
