Severity CVSS v4.0:
MEDIUM
Type:
CWE-331 Insufficient Entropy
Publication date:

Last modified:

Description

A cryptographic<br /> weakness exists in the Omada adoption protocol where session encryption keys<br /> used to protect communications between controllers and managed devices may be<br /> predictable due to insufficient entropy in session key generation.<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> An attacker<br /> who successfully intercepts adoption-related communications may be able to recover<br /> session encryption keys and decrypt affected communications.
