CVE-2025-0680 Overview
CVE-2025-0680 is a critical command injection vulnerability (CWE-78) affecting the device cloud RPC command handling process. This vulnerability allows remote attackers to take control over arbitrary devices connected to the cloud infrastructure without requiring authentication or user interaction. The flaw exists in how the affected products process RPC commands, enabling attackers to inject malicious operating system commands that are executed with elevated privileges.
Critical Impact
Remote attackers can exploit this vulnerability to gain complete control over cloud-connected devices, potentially compromising entire IoT/ICS deployments and enabling lateral movement across connected infrastructure.
Affected Products
- New Rock Technologies cloud-connected devices
- Industrial Control Systems (ICS) devices with vulnerable cloud RPC implementations
- IoT devices utilizing affected cloud management interfaces

Technical Details for CVE-2025-0680
Vulnerability Analysis
This vulnerability stems from improper neutralization of special elements used in an OS command (CWE-78). The device cloud RPC command handling process fails to properly validate and sanitize input before passing it to system-level command execution functions. This allows an attacker to craft malicious RPC requests that include embedded operating system commands.
The attack can be executed remotely over the network without requiring any form of authentication or user interaction. The vulnerability affects the confidentiality, integrity, and availability of targeted systems, potentially allowing attackers to read sensitive data, modify device configurations, and disrupt normal operations.
Root Cause
The root cause of this vulnerability is insufficient input validation in the RPC command handler. When processing incoming cloud RPC requests, the affected software directly incorporates user-supplied data into system commands without proper sanitization or escaping of shell metacharacters. This classic command injection pattern allows attackers to break out of the intended command context and execute arbitrary commands on the underlying operating system.
Attack Vector
The attack is network-based, requiring no authentication or user interaction. An attacker can send specially crafted RPC requests to the cloud management interface, embedding malicious OS commands within the request parameters. These commands are then executed by the device with the privileges of the RPC handler process, typically running with elevated permissions to manage device operations.
The exploitation process involves:
- Identifying a cloud-connected device with the vulnerable RPC handler
- Crafting a malicious RPC request containing shell metacharacters and embedded commands
- Sending the request to the cloud interface
- The injected commands execute on the target device with system privileges
For detailed technical information about the vulnerability mechanism, refer to the CISA ICS Advisory ICSA-25-030-02.
Detection Methods for CVE-2025-0680
Indicators of Compromise
- Unusual RPC requests containing shell metacharacters such as ;, |, &, $(), or backticks
- Unexpected outbound network connections from cloud-connected devices
- Anomalous process spawning from the RPC handler service
- Log entries showing command execution failures or unusual syntax errors
Detection Strategies
- Implement network-level monitoring for malformed or suspicious RPC traffic patterns
- Deploy behavioral analysis to detect unauthorized command execution on managed devices
- Monitor for privilege escalation attempts following RPC command processing
- Analyze cloud management logs for requests with embedded special characters
Monitoring Recommendations
- Enable verbose logging on cloud RPC handlers and forward logs to a SIEM
- Implement real-time alerting for command injection attack signatures
- Establish baseline behavior for RPC communications and alert on deviations
- Monitor device process trees for unexpected child processes from RPC services
How to Mitigate CVE-2025-0680
Immediate Actions Required
- Isolate affected cloud-connected devices from untrusted networks immediately
- Implement network segmentation to limit access to cloud management interfaces
- Review and restrict firewall rules to minimize exposure of RPC services
- Audit devices for signs of compromise and unauthorized access
Patch Information
Contact New Rock Technologies for patch availability and remediation guidance. For vendor contact information, visit the New Rock Tech Contact Page. Organizations should prioritize applying vendor-provided patches as soon as they become available due to the critical nature of this vulnerability.
Workarounds
- Restrict network access to cloud RPC interfaces using firewall rules and ACLs
- Implement application-layer filtering to block requests containing shell metacharacters
- Deploy a web application firewall (WAF) or API gateway with command injection detection rules
- Consider temporarily disabling cloud connectivity for critical devices until patches are applied
# Example firewall rule to restrict RPC access (adapt to your environment)
# Allow RPC access only from trusted management networks
iptables -A INPUT -p tcp --dport <RPC_PORT> -s <TRUSTED_NETWORK>/24 -j ACCEPT
iptables -A INPUT -p tcp --dport <RPC_PORT> -j DROP
