Rapid7 Nexpose Installer 6.6.39 Local Privilege Escalation


Vendor: Rapid7
Product web page: https://www.rapid7.com
Affected version: <=6.6.39

Summary: Rapid7 Nexpose is a vulnerability scanner which aims to support
the entire vulnerability management lifecycle, including discovery, detection,
verification, risk classification, impact analysis, reporting and mitigation.
It integrates with Rapid7's Metasploit for vulnerability exploitation.

Desc: Rapid7 Nexpose installer version prior to 6.6.40 uses a search path
that contains an unquoted element, in which the element contains whitespace
or other separators. This can cause the product to access resources in a parent
path, allowing local privilege escalation.

Tested on: Microsoft Windows 10 Enterprise, x64-based PC
           Microsoft Windows Server 2016 Standard, x64-based PC
