Rapid7 AppSpider 6.12 Privilege Escalation

`i>>?  
Rapid7 AppSpider 6.12 Web Application Vulnerability Scanner Elevation Of Privilege  
  
  
Vendor: Rapid7, Inc.  
Product web page: https://www.rapid7.com  
Affected version: 6.12.10.1  
  
Summary: While today's malicious attackers pursue a variety of  
goals, they share a preferred channel of attack - the millions  
of custom web, mobile, and cloud applications companies deploy  
to serve their customers. AppSpider dynamically scans these  
applications for vulnerabilities across all modern technologies,  
provides tools that speed remediation, and monitors applications  
for changes.  
  
Desc: The application suffers from an unquoted search path issue  
impacting the services 'AppSpider REST Server', 'AppSpider REST Service'  
and 'AppSpiderUpgradeService' for Windows deployed as part of AppSpider  
solution. This could potentially allow an authorized but non-privileged  
local user to execute arbitrary code with elevated privileges on the  
system. A successful attempt would require the local user to be able to  
insert their code in the system root path undetected by the OS or other  
security applications where it could potentially be executed during  
application startup or reboot. If successful, the local useras code  
would execute with the elevated privileges of the application.  
  
Tested on: Microsoft Windows 7 Professional SP1 (EN)  
Microsoft Windows 7 Ultimate SP1 (EN)
