CVE-2017-9137: 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)

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)

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 device's 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."

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.81%, higher than 56% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.
