Description

Delta Electronics InfraSuite Device Master versions prior to 1.0.5 contain a vulnerability in which the Device-status service listens on port 10100/ UDP by default. The service accepts the unverified UDP packets and deserializes the content, which could allow an unauthenticated attacker to remotely execute arbitrary code.

How to fix

Upgrade to a fixed version: Delta Electronics InfraSuite Device Master 1.0.5. Check the vendor advisory for mitigations.
