ABB Cylon Aspect 3.08.01 Remote Code Execution

`  
ABB Cylon Aspect 3.08.01 (bigUpload.php) Remote Code Execution  
  
  
Vendor: ABB Ltd.  
Product web page: https://www.global.abb  
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio  
Firmware: <=3.08.01  
  
Summary: ASPECT is an award-winning scalable building energy management  
and control solution designed to allow users seamless access to their  
building data through standard building protocols including smart devices.  
  
Desc: The ABB BMS/BAS controller suffers from a remote code execution  
vulnerability. The vulnerable uploadFile() function in bigUpload.php  
improperly reads raw POST data using the php://input wrapper without  
sufficient validation. This data is passed to the fwrite() function,  
allowing arbitrary file writes. Combined with an improper sanitization  
of file paths, this leads to directory traversal, allowing an attacker  
to upload malicious files to arbitrary locations. Once a malicious file  
is written to an executable directory, an authenticated attacker can  
trigger the file to execute code and gain unauthorized access to the  
building controller.
