Summary
by MITRE • 09/30/2026
A vulnerability has been found in Ziroom ZHOME A0101 1.0.1.0. This issue affects some unknown processing of the file /api/ZRnetwork/ping. Such manipulation of the argument url leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

The Ziroom ZHOME A0101 smart home gateway, specifically version 1.0.1.0, contains a critical security flaw within its network management interface that allows for remote command injection. This vulnerability is located in the processing logic of the /api/ZRnetwork/ping endpoint, which is designed to test network connectivity by sending ping requests to specified targets. The core technical deficiency lies in how this API handles user-supplied input for the url parameter. Instead of strictly validating or sanitizing the provided URL string before passing it to underlying system utilities, the application directly concatenates the untrusted input into a shell command execution context. This lack of proper input validation and output encoding creates a classic injection vector where an attacker can inject arbitrary operating system commands by manipulating the structure of the url argument.
From a technical perspective, this flaw aligns with CWE-78, which defines Improper Neutralization of Special Elements used in an OS Command, commonly known as OS Command Injection. The vulnerability arises because the application fails to distinguish between data and code within the command string passed to the operating system shell. By injecting special characters such as semicolons or pipe symbols into the url field, a malicious actor can terminate the intended ping operation and append additional commands for execution by the underlying Linux-based firmware of the gateway device. This type of error is frequently associated with CWE-20, which refers to Improper Input Validation, indicating that the software does not adequately verify whether the input meets expected format constraints before processing it further down the pipeline.
The operational impact of this vulnerability is severe due to its remote nature and the privileged context in which the affected service likely operates. Since the exploit can be launched remotely without requiring authentication or prior access to the local network, an attacker anywhere on the internet that has visibility into the device's IP address can initiate the attack. Successful exploitation allows for arbitrary code execution with the privileges of the application running the web server, which is often root or a high-privilege service account in embedded IoT devices. This grants the attacker full control over the Ziroom ZHOME A0101 gateway, enabling them to pivot into other parts of the home network, exfiltrate sensitive data such as Wi-Fi credentials and personal information stored on the device, or use the compromised hardware for botnet recruitment activities like DDoS attacks.
In terms of threat modeling and adversary behavior, this vulnerability maps directly to MITRE ATT&CK technique T1059, specifically Command and Scripting Interpreter sub-techniques such as sh (T1059.004) or bash (T1059.004). The ability to execute arbitrary commands remotely places this flaw in the initial access and execution phases of a cyber kill chain, allowing attackers to establish persistence or move laterally across connected IoT devices that may have weaker security postures than traditional IT infrastructure. Given that the exploit has been disclosed publicly and is available for use by threat actors, the window of opportunity for exploitation is wide open, especially since the vendor failed to respond to early notifications regarding this disclosure.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. The most effective solution is for the vendor to release a firmware update that patches the /api/ZRnetwork/ping endpoint by implementing strict input validation. This includes whitelisting allowed characters, rejecting inputs containing shell metacharacters such as ; | & $ ` \n, and using safe API functions like execve instead of system() or popen() when invoking external commands. If a patch is not immediately available, network-level controls should be implemented to restrict access to the management interface from untrusted networks, ideally placing it behind an authenticated VPN or isolating it on a separate VLAN with strict firewall rules that block inbound traffic from the public internet. Additionally, users should monitor for unusual outbound connections from their gateway and consider replacing the device if no vendor support is forthcoming, as IoT devices often lack mechanisms for automatic security updates once deployed in customer environments.
