Summary
by MITRE • 09/30/2026
A vulnerability was detected in Ziroom ZHOME A0101 1.0.1.0. This affects the function set_syslog of the file /api/ZRnetwork/set_syslog. The manipulation of the argument conloglevel/log_size results in command injection. The attack may be performed from remote. The exploit is now 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 hub running firmware version 1.0.1.0 contains a critical command injection vulnerability within its network management interface, specifically located in the set_syslog function of the /api/ZRnetwork/set_syslog endpoint. This flaw arises from insufficient input validation and sanitization mechanisms when processing user-supplied arguments for conloglevel and log_size parameters. As an unauthenticated remote attacker can interact with this API endpoint directly over the network, they are able to inject arbitrary operating system commands into the underlying device shell by manipulating these specific fields. The lack of proper escaping or filtering allows malicious payloads to break out of intended parameter boundaries and execute as part of a broader command string on the host system.
From a technical perspective, this vulnerability is classified under CWE-78 Improper Neutralization of Special Elements used in an OS Command commonly known as OS Command Injection. The root cause lies in the application's failure to validate or sanitize inputs before passing them to system-level commands for logging configuration purposes. When the conloglevel and log_size values are processed, they are concatenated into a command line without adequate checks against shell metacharacters such as semicolons, pipes, or backticks. This allows an attacker to append additional commands that will be executed with the privileges of the service running the API, which often includes root-level access in embedded IoT devices due to minimal security hardening practices typical in consumer smart home hardware.
The operational impact of this vulnerability is severe given its remote exploitability and public availability. Since the exploit code has been disclosed publicly, automated scanning tools and malicious actors can easily target vulnerable instances across the internet without requiring specialized knowledge or custom development efforts. Successful exploitation enables an attacker to gain full control over the Ziroom ZHOME hub, potentially allowing them to pivot into other devices on the local network, exfiltrate sensitive data such as Wi-Fi credentials or user logs, install persistent malware for botnet recruitment, or disrupt home automation services entirely. The device effectively becomes a compromised node within the broader IoT ecosystem, posing risks not only to individual homeowners but also to network integrity at large if left unpatched.
Industry frameworks categorize this type of attack under MITRE ATT&CK technique T1059 Command and Scripting Interpreter, specifically noting how attackers leverage OS command injection to execute arbitrary code on compromised systems. Furthermore, it aligns with CWE-287 Improper Authentication since the vulnerable endpoint appears accessible without requiring valid credentials, highlighting a fundamental flaw in access control design for critical management functions. The absence of vendor response despite early notification exacerbates the risk landscape, leaving users dependent solely on manual mitigation strategies until an official patch is released or alternative security controls are implemented externally.
To mitigate this vulnerability, immediate action should be taken to isolate affected devices from untrusted networks and restrict access to the administrative API endpoints via firewall rules if possible. Users should disable remote management features unless absolutely necessary and change default credentials to strong unique passwords where applicable. Network segmentation is highly recommended to limit lateral movement in case of compromise. Additionally, monitoring network traffic for unusual outbound connections or abnormal logging patterns can help detect potential exploitation attempts early. Organizations managing fleets of these devices should prioritize firmware updates once available and consider replacing hardware with models that demonstrate stronger security postures including regular patch cycles and transparent vulnerability disclosure policies.
