ownCloud 4.0.x / 4.5.x Remote Code Execution

`Vulnerability title: Remote Code Execution in ownCloud  
CVE: CVE-2014-2044  
Vendor: ownCloud  
Product: ownCloud  
Affected version: 4.0.x & 4.5.x  
Fixed version: 5.0  
Reported by: Alejo Murillo Moya  
  
Details:  
  
A remote code execution has been found and confirmed within ownCloud as  
an authenticated user. A successful attack could allow an authenticated  
attacker to execute PHP code, which could lead to a full compromise of  
the server and associated infrastructure. Please note that only the  
Windows versions of ownCloud are affected and that valid credentials are  
required.  
  
It is possible to create a custom .htaccess into the user's folder on  
Windows version of the application, which will enable PHP execution on  
the folder. This vulnerability exists because it is possible to bypass  
the internal blacklists using Windows ADS (Alternate Data Streams).
