CouchDB administrative users before 2.2.0 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 under which CouchDB runs, by bypassing the blacklist 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 and CVE-2018-8007.

CouchDB 3.0.0

The remote host is affected by the vulnerability described in GLSA-201812-06 (CouchDB: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in CouchDB. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could execute arbitrary code or escalate privileges.
  Workaround :

    There is no known workaround at this time.

Apache CouchDB PMC reports :

Database Administrator could achieve privilege escalation to the account that CouchDB runs under, by abusing insufficient validation in the HTTP API, escaping security controls implemented in previous releases.

According to its banner, the version of CouchDB running on the remote host is 1.x or 2.1.x prior to 2.1.2. It is, therefore, potentially affected by a privilege escalation which could allow a CouchDB administrative user to gain remote code execution on the underlying operating system. 

Note that Nessus did not actually test for these flaws but instead, has relied on the version in CouchDB's banner.
