CVE-2016-8742· NVD / CVE Program· CNA apache

The Windows installer that the Apache CouchDB team provides was vulnerable to local privilege escalation.

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.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
