Siemens has reported a critical vulnerability, CVE-2024-3400, in its RUGGEDCOM APE1808 devices configured with Palo Alto Networks Virtual NGFW, specifically those using the GlobalProtect gateway or portal. This vulnerability, rated with a CVSS v4 score of 10.0, highlights its severity, indicating it can be exploited remotely with low attack complexity. An attacker can leverage this command injection flaw to execute arbitrary code with root privileges, posing a significant threat to the security and integrity of the affected systems. The vulnerability impacts all versions of RUGGEDCOM APE1808 that are equipped with the specified configurations, making it a critical issue for users worldwide.
The technical root of the vulnerability lies in the improper neutralization of special elements used in a command within the GlobalProtect feature of the Palo Alto Networks PAN-OS software. This vulnerability could potentially allow an unauthenticated attacker to exploit the systems by creating arbitrary files that lead to remote code execution. Given the widespread deployment of these devices in critical manufacturing sectors, the implications of such a security breach are particularly alarming, as they could compromise critical infrastructure.
In response to this discovery, Siemens has outlined several mitigation measures to protect against this vulnerability. Users are urged to contact Siemens customer support to receive patch and update information that can resolve the vulnerability. Additionally, disabling the GlobalProtect gateway and portal, which are off by default in RUGGEDCOM APE1808 deployments, is recommended until the patches are applied. For customers with a Threat Prevention subscription, Siemens advises using Threat IDs 95187, 95189, and 95191 to block potential attacks, with further instructions available via Palo Alto Networks’ security advisory.
Furthermore, Siemens emphasizes the importance of securing network access to these devices with appropriate security mechanisms and recommends configuring the operational environment according to Siemens’ guidelines for industrial security. By following these best practices and implementing the recommended preventive measures, organizations can significantly reduce the risk of exploitation and safeguard their operations against this severe security threat. This proactive approach is crucial in maintaining the resilience and security of critical infrastructures utilizing the RUGGEDCOM APE1808 in a globally connected digital landscape.
