Introduction to CVE-2025-23116
CVE-2025-23116 is a critical vulnerability affecting the UniFi Protect Application by Ubiquiti Inc. This vulnerability occurs in versions earlier than 5.2.49 and allows a malicious actor with access to the local network to bypass authentication and control the UniFi Protect Cameras. The vulnerability is especially concerning for networks using the Auto-Adopt Bridge Devices feature, leaving them susceptible to unauthorized access and manipulation.
Vulnerability Details
Severity: Critical (CVSS base score: 9.6)
CVSS Vector: AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
This vulnerability is characterized by its ease of exploitation. An attacker with access to the same network as the cameras can circumvent authentication mechanisms, gaining control over the devices. This can potentially lead to unauthorized viewing or manipulation of camera feeds, posing significant risks to privacy and security.
Affected Products
The affected product is the UniFi Protect Application, specifically versions earlier than 5.2.49. Users running these versions with Auto-Adopt Bridge Devices enabled are particularly vulnerable.
Mitigation Strategies
To protect against CVE-2025-23116, follow these mitigation steps:
- Update Your Software: The most effective way to remediate this vulnerability is by updating the UniFi Protect Application to version 5.2.49 or later. Check for updates regularly to ensure your system remains protected from newly discovered vulnerabilities.
- Network Segmentation: Employ network segmentation to limit access to the UniFi Protect Cameras. Restrict the cameras’ network to only trusted devices and personnel.
- Disable Auto-Adopt Bridge Devices: If possible, disable the Auto-Adopt Bridge Devices feature unless absolutely necessary. This reduces the potential attack surface.
- Monitor Network Activity: Implement network monitoring to detect any unusual activity that could signify a security breach. Tools such as IDS/IPS can alert administrators to potential threats.
- Use Strong Authentication: Tighten access controls by implementing strong authentication mechanisms. Avoid using default credentials and employ multi-factor authentication where possible.
Conclusion
Vulnerabilities such as CVE-2025-23116 highlight the need for proactive security measures. By staying informed and implementing the recommended mitigation strategies, users can reduce the risks associated with this critical vulnerability. Regular updates and vigilant monitoring are key to maintaining the security and integrity of UniFi Protect Cameras and other networked devices.
