CVE-2014-9197 in ETG3000
Summary
by MITRE
The Schneider Electric ETG3000 FactoryCast HMI Gateway with firmware before 1.60 IR 04 stores rde.jar under the web root with insufficient access control, which allows remote attackers to obtain sensitive setup and configuration information via a direct request.

The Schneider Electric ETG3000 FactoryCast HMI Gateway represents a critical industrial control system component that serves as a bridge between industrial networks and enterprise systems. This device operates within the operational technology landscape where security vulnerabilities can have severe implications for industrial processes and infrastructure. The vulnerability identified in firmware versions prior to 1.60 IR 04 stems from a fundamental flaw in the web server implementation that exposes sensitive configuration files to unauthorized access. The rde.jar file contains critical system information that should remain protected within the device's secure environment, yet due to inadequate access controls, it becomes publicly accessible through direct web requests. This configuration error places the entire system at risk as attackers can obtain detailed setup information without requiring authentication or privileged access.
The technical flaw manifests as a classic path traversal and access control vulnerability that falls under the CWE-22 category for Path Traversal and CWE-285 for Improper Authorization. The device's web server fails to implement proper access controls when serving files from the web root directory, allowing any remote attacker to construct malicious URLs that directly request the rde.jar file. This vulnerability operates at the application layer and demonstrates poor security practices in web application development where sensitive files are not properly protected by authentication mechanisms or access control lists. The flaw essentially creates an information disclosure vulnerability that enables attackers to gather system configuration data that could be used for further exploitation or to understand the device's operational parameters.
The operational impact of this vulnerability extends beyond simple information disclosure and represents a significant risk to industrial control systems security. Attackers who successfully exploit this vulnerability can obtain sensitive setup information including network configurations, user credentials, and system parameters that could facilitate more sophisticated attacks. This information disclosure could enable adversaries to perform reconnaissance activities, identify system weaknesses, and develop targeted attacks against the industrial control environment. The exposure of rde.jar content may reveal system architecture details, communication protocols, and potential attack vectors that could compromise the integrity and availability of the entire industrial network. This vulnerability particularly affects environments where industrial control systems are connected to enterprise networks, creating potential pathways for lateral movement and persistent threats.
Mitigation strategies for this vulnerability require immediate firmware updates to version 1.60 IR 04 or later, which addresses the insufficient access control issue by implementing proper authorization checks for file access. Network segmentation and firewall rules should be implemented to restrict access to the HMI gateway to authorized personnel only, reducing the attack surface available to remote attackers. Access control mechanisms should be strengthened to ensure that only authenticated users with appropriate privileges can access sensitive system files. Security monitoring should be implemented to detect unusual access patterns or direct requests to sensitive files within the web root directory. Additionally, regular security assessments should be conducted to identify and remediate similar access control vulnerabilities in other industrial control system components, following best practices established in frameworks such as NIST SP 800-82 for industrial control systems security. The vulnerability highlights the importance of implementing proper security controls from the initial design phase of industrial systems, as specified in the MITRE ATT&CK framework's initial access and credential access tactics. Organizations should also consider implementing network access control solutions and intrusion detection systems to monitor for exploitation attempts targeting similar vulnerabilities in their industrial control environments.
