Recent security assessments have uncovered two significant vulnerabilities in TP-Link’s VIGI Network Video Recorder (NVR) systems, identified as CVE-2025-7723 and CVE-2025-7724. These flaws affect the VIGI NVR1104H-4P V1 and VIGI NVR2016H-16MP V2 models, posing substantial risks to the integrity and security of surveillance infrastructures.
Understanding the Vulnerabilities
CVE-2025-7723: Authenticated Command Injection
This vulnerability is an operating system (OS) command injection flaw that requires authenticated access. Attackers who have logged into the system can inject and execute arbitrary OS-level commands. With a Common Vulnerability Scoring System (CVSS) v4.0 score of 8.5, this issue is deemed high-severity. Exploitation could lead to unauthorized control over the NVR, allowing malicious actors to manipulate surveillance footage, alter device configurations, or use the NVR as a gateway for further network intrusions.
CVE-2025-7724: Unauthenticated Command Injection
This flaw is particularly alarming due to its unauthenticated nature, meaning attackers can exploit it without any login credentials. Assigned a CVSS v4.0 score of 8.7, it enables remote execution of arbitrary commands on affected devices. Such exploitation can result in complete system compromise, including unauthorized access to video data, disruption of surveillance operations, and potential lateral movement within the network.
Impacted Devices and Firmware Versions
The vulnerabilities specifically affect the following devices and firmware versions:
– VIGI NVR1104H-4P V1: Firmware versions prior to 1.1.5 Build 250518.
– VIGI NVR2016H-16MP V2: Firmware versions before 1.3.1 Build 250407.
Potential Consequences of Exploitation
If these vulnerabilities are exploited, the consequences could be severe:
– Unauthorized Access: Attackers could gain control over the NVR, accessing live feeds and recorded footage without permission.
– Data Manipulation: Malicious entities might alter or delete surveillance data, compromising the integrity of security records.
– Network Compromise: The NVR could serve as an entry point for attackers to infiltrate the broader network, potentially leading to further exploitation of connected systems.
Mitigation Measures
To address these vulnerabilities, TP-Link has released firmware updates and strongly recommends immediate deployment:
– VIGI NVR1104H-4P V1: Upgrade to firmware version 1.1.5 Build 250518.
– VIGI NVR2016H-16MP V2: Upgrade to firmware version 1.3.1 Build 250407.
Users should download the latest firmware directly from TP-Link’s official support channels. After updating, it’s crucial to verify all security settings to ensure they remain properly configured.
Additional Security Recommendations
Beyond firmware updates, consider implementing the following measures to enhance security:
– Network Segmentation: Isolate NVRs from critical network resources to limit potential attack surfaces.
– Access Controls: Restrict access to NVRs to authorized personnel only, using strong authentication methods.
– Regular Monitoring: Continuously monitor network traffic and system logs for unusual activities that may indicate attempted exploitation.
Conclusion
The discovery of CVE-2025-7723 and CVE-2025-7724 underscores the importance of proactive cybersecurity measures in protecting surveillance infrastructures. By promptly applying firmware updates and adhering to recommended security practices, organizations can mitigate the risks associated with these vulnerabilities and safeguard their systems against potential attacks.
