Ceragon FibeAir IP-10 wireless radios through 7.2.0 have a default password of mateidu for the mateidu account (a hidden user account established by the vendor). This account can be accessed via both the web interface and SSH. In the web interface, this simply grants an attacker read-only access to the devices settings. However, when using SSH, this gives an attacker access to a Linux shell. NOTE: the vendor has commented The mateidu user is a known user, which is mentioned in the FibeAir IP-10 User Guide. Customers are instructed to change the mateidu user password. Changing the user password fully solves the vulnerability.

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
Fiberair_ip-10_firmware Ceragon * 7.2.0 (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.
