The ABB Cylon Aspect BMS/BAS controller allows users to bypass authentication by setting the 'content' POST parameter. This enables an attacker to inject arbitrary configuration overrides, potentially leading to unauthorized changes and compromising system integrity. The vulnerability can be exploited to update the /usr/local/aam/etc/override.properties file. This file contains critical configuration overrides such as enabling overrides (Override.enabled=true) and setting specific properties like debug.level=1. The runjava.VARIANT* script then sources this file during execution, applying the overrides when the system reboots or the application restarts. This allows attackers to manipulate critical system settings, potentially causing performance degradation, introducing security risks, or resulting in a denial of service scenario.

An authenticated access vulnerability in the aspectMemory.php script of ABB Cylon Aspect BMS/BAS controllers allows attackers to set arbitrary values for Java heap memory parameters (HEAPMIN and HEAPMAX). This configuration is written to /usr/local/aam/etc/javamem. The absence of input validation can lead to system performance degradation, Denial-of-Service (DoS) conditions, and crashes of critical Java applications.

The obtainPorts.php script is accessible without authentication, allowing unauthorized users to retrieve and manipulate configuration parameters. This includes the ability to modify critical settings such as port values, potentially disrupting system functionality or enabling further exploitation.

The ABB BMS/BAS controller suffers from an unauthenticated blind OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'portValue' HTTP GET parameter called by obtainPorts.php script.

The portQueueAjax.php endpoint on ABB Cylon Aspect BMS/BAS controller is accessible without authentication, potentially exposing sensitive port statistics and network activity metrics. An attacker could leverage this information to map the network, identify critical systems, and plan further attacks.

The ABB Cylon Aspect BMS/BAS system suffers from an unauthenticated configuration disclosure vulnerability. This can be exploited to retrieve sensitive configuration data, including file paths, environment settings, and the location of system scripts. These exposed configuration files may allow an attacker to gain insights into the system's structure, facilitating further attacks or unauthorized access.

An unauthenticated vulnerability in ABB Cylon Aspect BMS/BAS allows the download of an SQLite3 database file, exposing sensitive information stored in several tables. This vulnerability could lead to unauthorized access to system data, enabling information disclosure and potential exploitation of critical building management or automation systems.

ABB Cylon Aspect is affected by multiple Server-Side Request Forgery (SSRF) vulnerabilities. These vulnerabilities allow authenticated attackers to exploit APIs and internal functions to make arbitrary network requests. This could result in unauthorized access to internal systems, data exfiltration, or bypassing firewall protections.

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.

The ABB BMS/BAS controller suffers from an authenticated reflected cross-site scripting vulnerability. Input passed to the GET parameter 'port' is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML/JS code in a user's browser session in context of an affected site.
