Vulnerability in ABB Cylon ASPECT 3.08.01 allows information disclosure via unauthenticated access.
<html><body><p>ABB Cylon Aspect 3.08.01 (pupDumpStats.php) Information Disclosure


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: &lt;=3.08.01

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.
The AAM PUP (Primary Utility Protocol) is a proprietary protocol supported
by certain building management systems, such as the ABB MATRIX-2 series
controllers. It is used for communication and integration with various
utility devices within a building's control system. This protocol supports
supervisory functions like energy management, alarm and event handling,
historical trending, and scheduling.

Desc: The ABB Cylon ASPECT system contains an unauthenticated information
disclosure vulnerability in the pupDumpStats.php script. When this endpoint
is accessed, it triggers the download of a sensitive debug file located at
/usr/local/aam/var/pupdbg.dump. This file may contain internal system information,
including protocol states, transaction logs, and system mappings. The vulnerability
arises from an Insecure Direct Object Reference (IDOR) issue, where the script
does not validate or authenticate the requester before allowing access to the
debug file. Exploiting this flaw enables an attacker to retrieve sensitive
operational data, potentially aiding in further exploitation of the system.

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