What is CVE-2016-8742?
CVE-2016-8742 is a high-severity vulnerability in Apache CouchDB, published on 12 Feb 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The Windows installer that the Apache CouchDB team provides was vulnerable to local privilege escalation. All files in the install inherit the file permissions of the parent directory and therefore a non-privileged user can substitute any executable for the nssm.exe service launcher, or CouchDB batch or binary files. A subsequent service or server restart will then run that binary with administrator privilege. This issue affected CouchDB 2.0.0 (Windows platform only) and was addressed in CouchDB 2.0.0.1.
