Unauthenticated Command Injection in Belkin Wemo Enabled Crock-Pot UPnP API

IdentifiersCVE-2019-12780CWE-78· Improper Neutralization of Special…

CVE-2019-12780 is a command injection vulnerability in the Belkin Wemo Enabled Crock-Pot UPnP API. The flaw is exposed through the SetSmartDevInfo action, where the SmartDevURL argument is not properly sanitized before being used by the device. An attacker can send a crafted POST request to /upnp/control/basicevent1 and inject operating-system commands via SmartDevURL. According to the provided content, exploitation does not require authentication.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary command execution on the vulnerable device without authentication. This can enable full compromise of the appliance’s underlying system, including modification of device behavior, execution of attacker-supplied payloads, persistence, and potential use of the device as a foothold for further activity on the local network.

Mitigation

If you can’t patch tonight, do this now.

Until patched, restrict network access to the device’s UPnP control interface, especially /upnp/control/basicevent1, to trusted management hosts only. Do not expose the device to untrusted networks. Segment IoT devices onto isolated VLANs or dedicated networks, apply ACLs or firewall rules to limit lateral access, and monitor for unexpected POST requests to the UPnP endpoint or anomalous command execution behavior. If the device is not required, disconnect it from the network.

Remediation

Patch, then assume compromise.

Apply the vendor-provided firmware update or patch that corrects input handling in the Wemo UPnP API, specifically the processing of the SmartDevURL parameter in SetSmartDevInfo. If a fixed firmware version is available from Belkin/Wemo, upgrade affected Crock-Pot devices to that version. Replace unsupported devices that no longer receive security updates.
