Use of default credentials for the telnet server in BASETech GE-131 BT-1837836 firmware 20180921 allows remote attackers to execute arbitrary system commands as the root user.

Weakness

The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.

Affected Software

Name Vendor Start Version End Version
Ge-131_bt-1837836_firmware Basetech 20180921 (including) 20180921 (including)

Extended Description

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
