CVE-2025-23116

Comprehensive Technical Analysis of CVE-2025-23116

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-23116 Description: An Authentication Bypass vulnerability in the UniFi Protect Application with Auto-Adopt Bridge Devices enabled could allow a malicious actor with access to the adjacent network to take control of UniFi Protect Cameras. CVSS Score: 9.6

Severity Evaluation: The CVSS score of 9.6 indicates a critical vulnerability. This high score is due to the potential for complete control of UniFi Protect Cameras, which can lead to significant security breaches, including unauthorized surveillance, data exfiltration, and potential physical security risks.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Network Access: The attacker must have access to the adjacent network where the UniFi Protect Cameras are deployed.
2. Auto-Adopt Feature: The vulnerability is exploited through the Auto-Adopt Bridge Devices feature, which is designed to simplify the adoption of new devices but can be misused to bypass authentication.

Exploitation Methods:

1. Network Scanning: The attacker scans the network to identify UniFi Protect Cameras.
2. Authentication Bypass: The attacker exploits the vulnerability to bypass the authentication mechanism, gaining control over the cameras.
3. Command Injection: Once authenticated, the attacker can inject commands to manipulate the cameras, including changing settings, accessing video feeds, and potentially disabling the cameras.

3. Affected Systems and Software Versions

Affected Systems:

• UniFi Protect Application
• UniFi Protect Cameras

Software Versions:

• Specific versions affected are not mentioned in the provided information. However, it is crucial to identify the exact versions impacted by this vulnerability through further analysis or vendor communication.

4. Recommended Mitigation Strategies

Immediate Actions:
