Security Bulletin
This security bulletin contains one high risk vulnerability.
EUVDB-ID: #VU17373
Risk: High
CVSSv3.1: 6.6 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:H/RL:W/RC:C]
CVE-ID: N/A
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe 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.
The vendor has released a workaround, and is in the process of putting together an official fix.
