### Impact CSS Selector expressions are not properly encoded, which can lead to XSS (cross-site scripting) vulnerabilities. ### Patches This is patched in v1.14.0. ### Workarounds Users can apply encoding manually to their selectors, if they are unable to upgrade.

ABB Cylon Aspect BMS/BAS is vulnerable to a critical flaw in the AuthenticatedHttpServlet within its application server, enabling remote attackers to bypass authentication by setting the Host: 127.0.0.1 header. This deceives the server into processing requests as if they originate from localhost, granting unauthorized access to privileged operations. This bypass grants access to privileged functionality, including the DeplomentServlet, which is vulnerable to directory traversal. By leveraging this, an attacker can write arbitrary PHP files outside the intended directory scope. When combined, these issues allow remote attackers to upload a malicious PHP shell and execute system commands with the privileges of the web server, leading to full system compromise.

ABB Cylon Aspect BMS/BAS is vulnerable to a critical flaw in the AuthenticatedHttpServlet within its application server, enabling remote attackers to bypass authentication by setting the Host: 127.0.0.1 header. This deceives the server into processing requests as if they originate from localhost, granting unauthorized access to privileged operations. Specifically, this vulnerability impacts the UserManager and GroupManager servlets, allowing unauthenticated attackers to create and remove users and groups without credentials. The flaw stems from the servlet’s automatic authorization of localhost requests as the aamuser account, exposing these sensitive functions to both local and remote exploitation. By leveraging this bypass, attackers can manipulate user and group configurations, potentially escalating privileges or disrupting system access controls.

The ABB BMS/BAS controller suffers from an authenticated blind OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'instance' HTTP POST parameter called by the logMixDownload.php script and dependant on SELECTED=ALL case.

The ABB BMS/BAS controller suffers from an authenticated blind OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'instance' HTTP POST parameter called by the productRemovalUpdate.php script. The token (key POST param) needs to be set to 159 to trigger the command execution.

ABB Cylon Aspect MIX's IPConfigServlet allows unauthenticated network config changes via the Host: 127.0.0.1 bypass, writing to /etc/hosts and config files. Attackers can redirect traffic (e.g. localhost to 1.2.3.4) or disrupt connectivity, amplifying impact with network restarts.

The ABB Cylon Aspect BAS controller is vulnerable to an authenticated hybrid path traversal vulnerability in logYumLookup.php due to insufficient validation of the logFile parameter. The script checks for the presence of an expected path (/var/log/yum.log) using strpos(), which can be bypassed by appending directory traversal sequences. This allows an authenticated attacker to read arbitrary files on the system, potentially exposing sensitive configuration files, credentials, or logs. The issue stems from a lack of proper path normalization and strict path validation, enabling attackers to escape the intended directory restriction.

The ABB BMS/BAS controller is vulnerable to code execution and sudo misconfiguration flaws. An authenticated remote code execution vulnerability in the firmware update mechanism allows an attacker with valid credentials to escalate privileges and execute commands as root. The process involves uploading a crafted .bsx file through projectUpdateBSXFileProcess.php, which is then moved to htmlroot and executed by projectUpdateBSXExecute.php. This script leverages sudo to run the uploaded bsx file, enabling the attacker to bypass input validation checks and execute arbitrary code, leading to full system compromise and unauthorized root access.
