CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Apache CouchDB 2.0.0. It has been declared as critical. This vulnerability affects an unknown code block of the file nssm.exe of the component Windows Installer. The manipulation as part of a Binary File leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
