Instances of the UniFi Network Application running on a UniFi Gateway Console and versions 7.5.176 and earlier implement device adoption with improper access control logic. This vulnerability allows a malicious actor with preexisting access to the network to potentially gain access to sensitive device configuration information.
The CVSS score for this vulnerability is 5.3, classified as medium severity. This level of severity indicates that organizations should address the issue in their priority patch cycle.
Risk to organizations includes unauthorized access to device configurations, which could lead to further exploitation of network resources. Organizations should prioritize patching immediately to prevent potential breaches.
As of now, there are no known exploits publicly available for this vulnerability, and it has not been added to the Known Exploited Vulnerabilities (KEV) catalog.
Vulnerability Details
The vulnerability is identified as CVE-2023-41721. It affects the UniFi Network Application versions 7.5.176 and earlier. The vulnerability is classified under CWE-284 which refers to improper access control.
The CVSS 3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating that the attack vector is network-based, with low complexity and no privileges required.
Technical Analysis
The root cause of this vulnerability lies in the improper access control logic implemented in the UniFi Network Application. This allows unauthorized users to exploit the device adoption process.
The attack vector is network-based, which means an attacker must have access to the same network as the vulnerable device. The attack complexity is low, requiring no special privileges or user interaction.
The confidentiality impact is low since access is to configuration information, while integrity and availability impacts are none.
Risk & Impact Analysis
Organizations deploying the affected versions of the UniFi Network Application may face significant risks. An attacker with network access could exploit this vulnerability to access sensitive configurations, potentially leading to further attacks on the network.
The urgency for remediation is high, as the exploitation could lead to unauthorized network access and configuration changes. Organizations should address this vulnerability in their priority patch cycle.
