# 2.12. CVE-2018-8007: Apache CouchDB Remote Code Execution

Date:

  30.04.2018

Affected:

  All Versions of Apache CouchDB

Severity:

  Low

Vendor:

  The Apache Software Foundation

## 2.12.1. Description

CouchDB administrative users can configure the database server via HTTP(S). Due to insufficient validation of administrator-supplied configuration settings via the HTTP API, it is possible for a CouchDB administrator user to escalate their privileges to that of the operating system’s user that CouchDB runs under, by bypassing the backlist of configuration settings that are not allowed to be modified via the HTTP API.

This privilege escalation effectively allows a CouchDB admin user to gain arbitrary remote code execution, bypassing CVE-2017-12636

## 2.12.2. Mitigation

All users should upgrade to CouchDB 1.7.2 or 2.1.2.

Upgrades from previous 1.x and 2.x versions in the same series should be seamless.

Users on earlier versions, or users upgrading from 1.x to 2.x should consult with upgrade notes.
