Description
This security bulletin contains information about 1 vulnerability.
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a remote attacker to conduct DDoS attack.
The weakness exists due to a flaw in a "discovery service" running on port 10001/UDP. A remote attacker can send small packets of 56 bytes to port 10001/UDP on Ubiquiti devices, which are reflecting and relaying the packets to a target's IP address amplified to a size of 206 bytes (amplification factor of 3.67).
Note: the vulnerability has been actively exploited since July 2018.
