UBUNTU-CVE-2018-11769 (CVE-2018-11769)

Vulnerability from osv_ubuntu – Published: 2018-08-08 15:29 – Updated: 2025-10-24 04:47 – Source website

Details

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.

Severity

7.2 (High)
