possible to obtain the local account credentials by brute force.

Updated firmware is available that provides account lockout functionality when brute force attacks are detected.

CVSSv3 scores are calculated in accordance with CVSS version 3.0 (https://www.first.org/cvss/user-guide)

 

 

Impact
 

Local account credentials may be extracted from the device via brute force guessing attacks.
