Apache CouchDB JSON Remote Privilege Escalation Vulnerability

Description

Due to differences in CouchDB's Erlang-based JSON parser and JavaScript-based JSON parser, it is possible to submit _users documents with duplicate keys for 'roles' used for access control within the database, including the special case '_admin' role, that denotes administrative users. In combination with 'CVE-2017-12636' (Remote Code Execution), this can be used to give non-admin users access to arbitrary shell commands on the server as the database system user.

Remediation

Upgrade to the latest version of CouchDB
