Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly validates the macType argument in the macAddrClone function to prevent command injection payloads from being executed.

prevent

Requires identification, reporting, and correction of the specific command injection flaw in luci/controller/api/zrMacClone.lua, including patching or mitigation.

preventdetect

Vulnerability monitoring and scanning detects exposed Ziroom ZHOME A0101 devices vulnerable to CVE-2026-1802 and its public exploit for prioritized remediation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

Command injection in public-facing API endpoint (zrMacClone.lua) directly enables remote unauthenticated exploitation of a network device for arbitrary Unix command execution.

Deeper analysisAI

CVE-2026-1802 is a command injection vulnerability affecting the Ziroom ZHOME A0101 1.0.1.0 device. The flaw resides in the macAddrClone function within the file luci/controller/api/zrMacClone.lua, where manipulation of the macType argument enables command injection. Published on 2026-02-03, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) and is linked to CWEs-74 and CWE-77.

The vulnerability is exploitable remotely by unauthenticated attackers requiring low complexity and no user interaction. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling arbitrary command execution on the affected device.

Advisories from VulDB and a GitHub repository detail the issue, including a publicly released exploit at https://github.com/jinhao118/cve/blob/main/ziru_router_command_injection.md. The vendor was contacted early regarding disclosure but provided no response, and no patches or mitigations are mentioned.

Notable context includes the public availability of the exploit, which may facilitate attacks against vulnerable Ziroom ZHOME A0101 1.0.1.0 devices.
