CVE-2025-47419: CWE-319 Cleartext Transmission of Sensitive Information in Crestron Automate VX
Cleartext Transmission of Sensitive Information vulnerability in Crestron Automate VX allows Sniffing Network Traffic. The device allows Web UI and API access over non-secure network ports which exposes sensitive information such as user passwords. This issue affects Automate VX: from 5.6.8161.21536 through 6.4.0.49.
AI Analysis
Technical Summary
CVE-2025-47419 is a critical vulnerability affecting Crestron Automate VX versions from 5.6.8161.21536 through 6.4.0.49. The vulnerability is classified under CWE-319, which involves the cleartext transmission of sensitive information. Specifically, the affected Crestron Automate VX devices allow access to their Web UI and API over non-secure network ports, meaning that sensitive data such as user passwords are transmitted without encryption. This lack of transport layer security enables attackers with network access to perform passive network sniffing to intercept credentials and other sensitive information. The vulnerability has a CVSS 4.0 base score of 10.0, indicating a critical severity with network attack vector, low attack complexity, no privileges or user interaction required, and a high impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical nature of the vulnerability make it a significant threat. The vulnerability affects the core management interface of Crestron Automate VX, a widely used automation and control platform in enterprise and commercial environments, which could lead to unauthorized access, control hijacking, and potential lateral movement within affected networks.
Potential Impact
For European organizations, the impact of this vulnerability is substantial. Crestron Automate VX is commonly deployed in corporate, educational, and government facilities for managing building automation, AV systems, and other critical infrastructure. The exposure of credentials via unencrypted channels can lead to unauthorized administrative access, enabling attackers to manipulate automation systems, disrupt operations, or exfiltrate sensitive data. This can result in operational downtime, compromise of physical security controls, and potential data breaches. Given the criticality of the CVSS score and the fact that exploitation requires only network access without authentication or user interaction, attackers could leverage this vulnerability to gain footholds in networks, especially in environments where network segmentation is weak. Additionally, the breach of automation systems can have cascading effects on other connected systems, increasing the overall risk profile for affected European entities.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should immediately restrict access to Crestron Automate VX Web UI and API interfaces to trusted networks only, ideally via VPNs or secure management VLANs. Network administrators should implement strict firewall rules to block non-secure ports from being accessible externally or from untrusted internal segments. Where possible, organizations should enforce the use of encrypted communication protocols such as HTTPS and secure API endpoints, ensuring TLS is enabled and properly configured. Since no patches are currently available, organizations should monitor Crestron’s advisories for updates and apply patches promptly once released. Additionally, organizations should conduct network traffic monitoring to detect any suspicious sniffing or unauthorized access attempts. Implementing network segmentation to isolate automation systems from general user networks will reduce exposure. Finally, credential rotation and multi-factor authentication for administrative access should be enforced to limit the impact of credential compromise.
