🚨 Overview: Critical Security Flaws in TP‑Link VIGI NVRs
TP‑Link has issued an urgent security advisory for its VIGI series of network video recorders. Two high‑severity vulnerabilities—CVE‑2025‑7723 and CVE‑2025‑7724—impact model VIGI NVR1104H‑4P V1 and VIGI NVR2016H‑16MP V2. These flaws permit OS-level command injection, with one vulnerability allowing remote attackers to compromise devices without authentication.(turn0search0, turn0search12).
🧨 Deep Dive: Understanding the Vulnerabilities
🔐 CVE‑2025‑7723 (Authenticated Command Injection)
- Attackers with valid credentials can inject arbitrary OS-level commands.
- Rated as High severity with a CVSS v4.0 score of 8.5.
- Exploitation may manipulate device settings, tamper with surveillance footage, or pivot into internal networks.(turn0search0)
🚫 CVE‑2025‑7724 (Unauthenticated Command Injection)
- The more dangerous of the two—no login required to exploit.
- Given a CVSS v4.0 score of 8.7, reflecting the elevated risk.
- An attacker on the network (even remotely) can execute arbitrary commands on the underlying operating system.(turn0search0)
Affected firmware versions:
- VIGI NVR1104H‑4P V1: prior to 1.1.5 Build 250518
- VIGI NVR2016H‑16MP V2: prior to 1.3.1 Build 250407(turn0search0)
⚠️ Why It’s Dangerous: Surveillance Systems at Risk
- Critical infrastructure exposure: NVRs store sensitive video footage; compromise could lead to data theft or sabotage.
- Lateral movement potential: Attackers can use the device as a foothold into broader network systems.
- Deployment prevalence: Many organizations overlook NVRs during patch audits.
- Ease of exploitation: Even unauthenticated attackers can gain system access for CVE‑2025‑7724.
🛠️ Recommended Actions: Protect Your Surveillance Infrastructure
✅ Immediate Firmware Updates
- NVR1104H‑4P V1: upgrade to 1.1.5 Build 250518
- NVR2016H‑16MP V2: upgrade to 1.3.1 Build 250407(turn0search0)
✅ Verify Post-Update Integrity
- After updating, confirm all settings are secured and correct.
✅ Network Segmentation & Access Control
- Place NVRs in isolated VLANs or restricted network zones.
- Only grant access to trusted hosts and services.
✅ Monitor for Anomalous Behavior
- Watch for unusual process activity, unexpected shell commands, or external connections emanating from the device.
✅ Review User Access Policies
- Ensure administrative interfaces are not exposed to the internet.
- Use strong credentials and change default passwords.
✅ Audit Logs & Configure Alerts
- If supported, enable command logging and alert on any suspicious user or system actions.
🧠 Expert Insight
“These NVR vulnerabilities are a stark reminder that security must extend beyond main servers—surveillance devices can be silent entry points into critical networks.”
