Executive brief
UniFi OS is network management software used by organizations to configure and monitor network infrastructure devices. A vulnerability in the OS allows a privileged network-connected attacker to inject and execute arbitrary commands on the host device, potentially gaining full control of the system and the ability to modify network configurations or access sensitive data.
Technical details
An improper input validation vulnerability in UniFi OS Server allows command injection on the host device. The vulnerability requires the attacker to have network access and high privileges to exploit it. By sending crafted input that bypasses validation checks, an attacker can inject and execute arbitrary system commands with the privileges of the UniFi OS process. This could lead to complete system compromise, unauthorized access to network credentials, or lateral movement within the network infrastructure.
