Couchbase is a NoSQL database technology primarily used for interactive web and mobile applications. It is widely employed by organizations needing high performance, scalability, and distributed capabilities in their database systems. Enterprises across sectors, such as finance, retail, and healthcare, utilize Couchbase for real-time operational analytics and content management. Its ability to serve dynamic data for online transaction processing makes it a popular choice. Organizations also appreciate Couchbase's flexibility in storing multiple data models, supporting a variety of use cases. Overall, Couchbase is integrated into IT infrastructures to power applications that require low-latency access to data and session handling.
The vulnerability detected pertains to the exposure of the Couchbase Buckets REST API without requiring authentication. This exposure means that sensitive operations or data within the Couchbase instance can be accessed without proper authorization controls. The security flaw might allow unauthorized access to bucket management functions, leading to unmonitored data manipulation or leakage. Detecting such improper configurations is crucial as they can serve as entry points for various cyber threats. Developers must address these exposures to prevent attackers from leveraging them in significant attacks. Properly securing Couchbase deployments against unauthorized API access is essential to maintain the integrity of application environments.
Technically, the vulnerability involves the unauthorized access to the Couchbase REST API designated for managing buckets. The endpoint '/pools/default/buckets' responds with sensitive bucket information such as "couchbase", "bucket", and "data" in configurations where authentication controls are missing. The API is capable of providing JSON-formatted data, indicated by the 'application/json' content type in HTTP headers. To exploit the vulnerability, an attacker would send a GET request to this endpoint and receive a 200 HTTP status response combined with couchbase-specific terms. This indicates a successful detection of open, unauthenticated API access used for bucket management.
If this vulnerability is exploited by malicious actors, the possible effects include unauthorized data access and manipulation within the Couchbase instance. Attackers could retrieve, alter, or delete bucket data, potentially disrupting application functionalities dependent on this data. Unauthorized actors might also assess sensitive information leading to further security breaches. Exploitation can cause data inconsistencies, affecting operational processes and causing financial or reputational damage. Moreover, the exposure could serve as a foothold for additional attacks, posing risks of escalated security incidents within the organizational infrastructure.
