Background
CouchDB is a database management system that provides a document-oriented NoSQL database. It is designed to be scalable, fault-tolerant, and easy to use. CouchDB allows users to store, retrieve, and manage their data using a flexible JSON-based document model. However, two vulnerabilities have been discovered in CouchDB that could potentially allow unauthorized users to gain administrative privileges and execute arbitrary shell commands.
Vulnerability Detail
The first vulnerability, identified as CVE-2017-12635, allows non-admin users to grant themselves admin privileges. This could lead to unauthorized access and control over the CouchDB instance, potentially compromising the confidentiality, integrity, and availability of the stored data. The second vulnerability, CVE-2017-12636, involves the execution of arbitrary shell commands as the CouchDB user. Attackers could exploit this vulnerability to execute malicious commands, potentially leading to further compromise of the system.
