Lifecycle Timeline
8DescriptionCVE.org
A vulnerability was detected in Ziroom ZHOME A0101 1.0.1.0. Affected by this issue is some unknown functionality of the file /api/ZRnetwork/firstLogin. Performing a manipulation of the argument firstLogin results in command injection. The attack is possible to be carried out remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Remote command injection in the Ziroom ZHOME A0101 smart-home device (firmware 1.0.1.0) lets an attacker who can reach the /api/ZRnetwork/firstLogin HTTP endpoint inject shell metacharacters through the 'firstLogin' parameter and execute arbitrary operating-system commands with the privileges of the underlying service. Publicly available exploit code exists (a proof-of-concept write-up is published on GitHub and the issue was reported via VulDB), and the vendor was contacted early but never responded, so no vendor patch is available. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to a ZHOME A0101 (firmware 1.0.1.0) device's HTTP API and the ability to reach the /api/ZRnetwork/firstLogin endpoint, then supplying shell metacharacters in the firstLogin parameter. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a CWE-77 command injection in the Ziroom ZHOME A0101 (1.0.1.0) smart-home device, reachable over the network at /api/ZRnetwork/firstLogin. … 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 identified at time of analysis - Ziroom was contacted about the disclosure and never responded, so there is no fixed firmware version to cite and upgrading is not currently an option. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Ziroom ZHOME A0101 devices on corporate and remote-worker networks and confirm whether firmware 1.0.1.0 is in use; isolate any affected device to a dedicated VLAN or guest segment with no route to internal systems, block inbound access to the /api/ZRnetwork/firstLogin endpoint at the perimeter and host firewall, and disable remote or WAN-facing management access. …
