#vulnerability

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.

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.

Multiple PHP and Java components across the system fail to properly sanitize user-supplied input before including it in application logs. In PHP, files like supervisorProxy.php directly embed values such as $_SERVER['REQUEST_URI'] and raw POST bodies into log messages without filtering, enabling attackers to inject arbitrary log entries using encoded newline characters. Similarly, Java classes using LoggerUtil.logger.* methods concatenate user-controlled strings like usernames and cookie keys into logs without validation. This systemic flaw allows for log forging, manipulating log content to obfuscate activity, insert misleading entries, or facilitate follow-up attacks.

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.

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 application suffers from an elevation of privileges vulnerability which can be used by a simple authenticated user that can change the executable file with a binary of choice. The vulnerability exist due to the improper permissions, with the 'M' flag (Modify) for 'Authenticated Users' group.

The same easily exploitable vulnerability was found in three of the apps that led to the compromise of victims' data.

Pingora versions prior to 0.5.0 which used the caching functionality in pingora-proxy did not properly drain the downstream request body on cache hits. This allows an attacker to craft malicious HTTP/1.1 requests which could lead to request smuggling or cache poisoning. This flaw was corrected in commit fda3317ec822678564d641e7cf1c9b77ee3759ff by ensuring that the downstream request body is always drained before a connection can be reused.

Hazel observes that cybercriminals often fumble teamwork, with fragile alliances crumbling over missed messages. Plus, how UAT-6382 is exploiting Cityworks and what you can do to stay secure.

A Chinese-speaking threat actor tracked as UAT-6382 has been linked to the exploitation of a now-patched remote-code-execution vulnerability in Trimble Cityworks to deliver Cobalt Strike and VShell. "UAT-6382 successfully exploited CVE-2025-0944, conducted reconnaissance, and rapidly deployed a variety of web shells and custom-made malware to maintain long-term access," Cisco Talos researchers
