DescriptionCVE.org

A flaw has been found in Ziroom ZHOME A0101 1.0.1.0. This affects an unknown part of the file /api/ZRnetwork/firstSetup_wifi. Executing a manipulation of the argument login_pwd can lead to command injection. The attack may be performed from remote. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

OS command injection in the Ziroom ZHOME A0101 smart-home device (firmware 1.0.1.0) allows an attacker who can reach the device's HTTP management API to execute arbitrary shell commands on the device by passing crafted shell metacharacters in the login_pwd argument of the /api/ZRnetwork/firstSetup_wifi endpoint. The vendor CVSS 4.0 vector (8.5, AV:N/AC:L/AT:N/PR:H/UI:N, with High confidentiality, integrity and availability impact plus changed scope) indicates that per the scoring model high privileges are required, although the independent assessment notes that because this is a first-time-provisioning endpoint the real privilege barrier may be weaker in practice and should be verified. …

Vulnerability AssessmentAI

Exploitation Exploitation targets the specific endpoint /api/ZRnetwork/firstSetup_wifi and requires supplying shell metacharacters in the login_pwd argument on a Ziroom ZHOME A0101 running firmware 1.0.1.0. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a CWE-77 OS command injection in the Ziroom ZHOME A0101 smart-home device (firmware 1.0.1.0), reachable over the network at /api/ZRnetwork/firstSetup_wifi via the login_pwd parameter. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch was identified at time of analysis: Ziroom was contacted about the disclosure and did not respond, so no fixed firmware version is available to cite. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all Ziroom ZHOME A0101 devices running firmware 1.0.1.0, isolate them on a dedicated VLAN with strict firewall rules that block access to the HTTP management API endpoint /api/ZRnetwork/firstSetup_wifi from untrusted networks, and disable the first-time provisioning endpoint if not required. …
