`  
ABB Cylon Aspect 3.08.00 (fileSystemUpdate.php) Insecure File Upload  
  
  
Vendor: ABB Ltd.  
Product web page: https://www.global.abb  
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio  
Firmware: <=3.08.00  
  
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: A vulnerability exists in the fileSystemUpdate.php endpoint of the  
ABB BEMS controller due to improper handling of uploaded files. The endpoint  
lacks restrictions on file size and type, allowing attackers to upload excessively  
large or malicious files. This flaw could be exploited to cause Denial-of-Service  
(DoS) attacks, memory leaks, or buffer overflows, potentially leading to system  
crashes or further compromise.
