CVE-2022-24706 Scanner

Apache CouchDB is an open-source document-oriented NoSQL database that uses JSON to store data, JavaScript for map/reduce indexes, and regular HTTP for its API. It's designed to cater to modern web and mobile apps, offering a scalable, fault-tolerant, and easy-to-use database solution. CouchDB’s replication protocol is a standout feature, enabling users to synchronize database copies on different servers seamlessly. Widely adopted for its ease of use and robustness, CouchDB is crucial for data storage and synchronization across distributed systems, including web applications, mobile apps, and enterprise-level systems.

CVE-2022-24706 is a critical vulnerability in Apache CouchDB that allows attackers to gain admin privileges and execute arbitrary commands remotely on improperly secured default installations. This flaw is particularly alarming as it requires no authentication for exploitation, thereby posing a significant threat to the confidentiality, integrity, and availability of data stored in CouchDB. The vulnerability stems from an insecure default configuration, underscoring the importance of proper database security setup and maintenance.

This vulnerability exploits the default Erlang cookie value monster used by CouchDB for node-to-node communication in clusters, which was inadequately protected in versions prior to 3.2.2. Attackers exploiting this vulnerability can send crafted requests to the database, achieving unauthorized admin access and the capability to execute arbitrary code. This breach can lead to data theft, unauthorized data manipulation, and potentially, full system compromise. The attack can be launched remotely without any form of legitimate access to the database, making it a severe risk to affected systems.

The exploitation of CVE-2022-24706 could lead to severe consequences, including unauthorized access and control over the CouchDB database, data exfiltration, database corruption or deletion, and potentially, lateral movement within the network infrastructure. Such incidents could disrupt business operations, compromise sensitive data, and tarnish the reputation of affected organizations. Immediate and effective remediation measures are crucial to mitigate this threat.
