Vendor/Project: Siemens
Product: RUGGEDCOM ROX MX5000

Description

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.16.5), RUGGEDCOM ROX MX5000RE (All versions < V2.16.5), RUGGEDCOM ROX RX1400 (All versions < V2.16.5), RUGGEDCOM ROX RX1500 (All versions < V2.16.5), RUGGEDCOM ROX RX1501 (All versions < V2.16.5), RUGGEDCOM ROX RX1510 (All versions < V2.16.5), RUGGEDCOM ROX RX1511 (All versions < V2.16.5), RUGGEDCOM ROX RX1512 (All versions < V2.16.5), RUGGEDCOM ROX RX1524 (All versions < V2.16.5), RUGGEDCOM ROX RX1536 (All versions < V2.16.5), RUGGEDCOM ROX RX5000 (All versions < V2.16.5). The 'tcpdump' tool in the web interface of affected devices is vulnerable to command injection due to missing server side input sanitation. This could allow an authenticated remote attacker to execute arbitrary code with root privileges.

Technical Analysis

CVE-2025-33024 is a critical vulnerability affecting multiple Siemens RUGGEDCOM ROX series devices, including the MX5000, MX5000RE, RX1400, RX1500, RX1501, RX1510, RX1511, RX1512, RX1524, RX1536, and RX5000 models running firmware versions prior to V2.16.5. The vulnerability stems from improper input validation in the 'tcpdump' tool accessible via the device's web interface. Specifically, the web interface fails to enforce server-side input sanitation, relying instead on client-side controls, which can be bypassed by an authenticated remote attacker. This flaw corresponds to CWE-602 (Client-Side Enforcement of Server-Side Security), where security controls are incorrectly implemented on the client side rather than the server side. Exploiting this vulnerability allows an attacker with valid credentials to perform command injection, executing arbitrary code with root privileges on the affected device. The CVSS v3.1 base score is 9.9, indicating a critical severity level, with attack vector as network (remote), low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability with a scope change. Although no known exploits are reported in the wild yet, the high severity and ease of exploitation make this a significant risk. Siemens has not yet published patches as of the provided data, so affected organizations must be vigilant and apply mitigations promptly once updates are available. The vulnerability affects critical industrial network infrastructure devices widely used in operational technology (OT) environments, making it a high-value target for attackers aiming to disrupt or gain control over industrial networks.

Potential Impact

For European organizations, especially those operating critical infrastructure such as energy, transportation, manufacturing, and utilities, this vulnerability poses a severe risk. Siemens RUGGEDCOM devices are commonly deployed in industrial control systems (ICS) and operational technology networks across Europe. Successful exploitation could lead to full compromise of these devices, enabling attackers to execute arbitrary commands with root privileges, potentially disrupting network communications, causing denial of service, or facilitating lateral movement within OT networks. This could result in operational downtime, safety hazards, data breaches, and significant financial and reputational damage. Given the critical nature of these devices in managing and securing industrial networks, the impact extends beyond IT to physical processes, increasing the risk of cascading failures. Furthermore, the vulnerability requires only authenticated access, which could be obtained through credential theft or phishing, increasing the attack surface. The lack of user interaction needed for exploitation further elevates the threat. European organizations must prioritize securing these devices to maintain operational resilience and comply with regulatory requirements related to critical infrastructure protection.

Mitigation Recommendations

1. Immediate mitigation should include restricting access to the web interface of affected RUGGEDCOM devices to trusted management networks only, using network segmentation and firewall rules to limit exposure. 2. Enforce strong authentication mechanisms and rotate credentials regularly to reduce the risk of unauthorized access. 3. Monitor device logs and network traffic for unusual activities indicative of exploitation attempts, such as unexpected command executions or abnormal tcpdump usage. 4. Disable or restrict the use of the 'tcpdump' tool via the web interface if possible until patches are available. 5. Implement multi-factor authentication (MFA) for device management interfaces to add an additional security layer. 6. Prepare for patch deployment by inventorying all affected devices and planning maintenance windows, as Siemens is expected to release firmware updates addressing this vulnerability. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection patterns targeting these devices. 8. Conduct security awareness training for personnel managing these devices to recognize phishing and credential compromise risks. 9. Consider deploying network anomaly detection solutions specialized for OT environments to identify lateral movement or exploitation attempts early. These targeted actions go beyond generic advice by focusing on access control, monitoring, and preparation specific to the affected Siemens RUGGEDCOM devices and their operational context.
