Weak Hashing in Omada Controller Adoption Process

Executive Summary

This vulnerability is a cryptographic weakness in the Omada device adoption process. During adoption, authentication credentials for site management are transmitted using a weak hashing algorithm that fails to provide adequate protection. An attacker who intercepts this traffic could recover valid credentials and gain unauthorized access to managed devices or controller-managed environments.

Detection Guidance

This vulnerability involves weak hashing of credentials during Omada device adoption. Detection requires monitoring network traffic for adoption-related authentication exchanges. Use packet capture tools like tcpdump or Wireshark to inspect adoption traffic for weak hash algorithms or plaintext credential transmission. Look for unencrypted or weakly encrypted credential exchanges during device adoption processes.
