- Affected
- Maven org.eclipse.paho:org.eclipse.paho.client.mqttv3 < 1.2.1
- Fixed in
- 1.2.1· Vendor fix available
- Issue
- In the Eclipse Paho Java client library version 1.2.0, when connecting to an MQTT server using TLS and setting a host name verifier, the result of that verification is not checked. This could allow one MQTT server to impersonate another and provide the client library with incorrect information.
Recommended action: Upgrade to 1.2.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
