ABB Cylon Aspect 3.08.02 (webServerUpdate.php) Input Validation Config Poisoning
Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.02

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 improper input validation on
the port POST parameter in the webServerUpdate.php script. This input is not
validated on the server side and relies on bypassable client-side checks using
the inString.js script to verify that the port parameter contains only characters
from the set (0123456789). Attackers can bypass these checks and supply arbitrary
integer values. Exploitation of this issue can result in configuration poisoning,
Denial of Service (DoS) through malformed configurations, or manipulation of
server settings via Cross-Site Request Forgery (CSRF) combined with authentication
bypass.
