<html><body><p>ABB Cylon Aspect 3.08.02 (escDevicesUpdate.php) Off-by-One Config Write DoS


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: &lt;=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: A vulnerability was identified in a PHP script where an off-by-one
error in array access could lead to undefined behavior and potential DoS.
The issue arises in a loop that iterates over an array using a &lt; condition,
allowing access to an out-of-bounds index. This can trigger errors or unexpected
behavior when processing data, potentially crashing the application. Successful
exploitation of this vulnerability can lead to a crash or disruption of service,
especially if the script handles large data sets. This issue can be triggered
via the rowCount POST parameter in the Electronic Security Control device update
script.

Tested on: GNU/Linux 3.15.10 (armv7l)
           GNU/Linux 3.10.0 (x86_64)
