No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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."

CISA SSVCTrack at low or medium mission impact; Track or Attend at high (mission-essential systems).

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
