Digiever NVR Flaws (CVE-2025-10264, CVE-2025-10265): Critical Vulnerabilities Exposed

Introduction

Network Video Recorders (NVRs) are central to modern surveillance setups—used by companies, governments, and individuals to record, store, and stream camera data. When these devices have critical bugs, the consequences are serious: exposure of sensitive data, camera hijacking, remote code execution, and breach of physical security.

Recently, two severe vulnerabilities were disclosed in Digiever NVR products:

CVE-2025-10264 – Exposure of Sensitive Information
CVE-2025-10265 – OS Command Injection

Both allow unauthenticated remote attackers to compromise devices with firmware version up to x.x.x.78. The vendor has released firmware version x.x.x.79 to remediate. twcert.org.tw+1

Vulnerability Summaries & Technical Details

CVE	Title	Attack Vector / Prerequisites	Impact	Severity (CVSS v3.1)
CVE-2025-10264	Exposure of Sensitive Information	Remote attacker, no authentication required, access over network to vulnerable Digiever NVR models. They can retrieve the system configuration file including plaintext credentials for the NVR device and connected cameras. Tenable®+1	Disclosure of credentials → risk of camera feed access, pivoting, further compromise.	10.0 (Critical) twcert.org.tw
CVE-2025-10265	OS Command Injection	Same scenario: unauthenticated remote access; attacker can inject arbitrary OS commands. Firmware ≤ x.x.x.78 affected. twcert.org.tw+1	Full remote code execution; takeover of device; possibility of malware, persistent compromise, disable surveillance.	9.8 (Critical) twcert.org.tw

Affected Products / Firmware

A wide range of Digiever NVR series:
DS-1200, DS-2100 Pro / Pro+ / UHD, DS-2200 UHD / UHD+, DS-4200 Pro / Pro+ / UHD / UHD+, DS-4100-RM, DS-4200-RM Pro+ / UHD, DS-8×00-RM Pro+, DS-8×00-SRM Pro+, DS-8×00-RM UHD, DS-16×00-RM Pro+ / UHD. twcert.org.tw
Firmware versions up to x.x.x.78 inclusive are vulnerable. twcert.org.tw
Fix: update to firmware version x.x.x.79 or later. twcert.org.tw

Exploit Scenarios & Risk Scenarios

Here are possible real-world exploit paths and risks:

An attacker scans for IPs of Digiever NVRs exposed on the internet (device search / Shodan). Since authentication is not required, CVE-10264 allows them to download configuration file → extract credentials → login to camera feeds or admin console.
With those credentials or via direct CVE-10265, attacker executes commands (remote shell, OS commands) to: disable recording, delete logs/videos, install backdoors, pivot into LAN, possibly reach other systems if NVR is on same network.
Physical security impact: Blind spots (camera turned off or feed manipulated), compromised video recording, remote monitoring.
Data privacy concerns: camera credentials often include username/password that may be shared or common; feeds may include personally identifiable information (PII).
Compliance / regulatory fallout: GDPR/PDPA etc., if video feeds containing PII are exposed.

Mitigation & Defense Steps (CyberDudeBivash Guidance)

Update Firmware Immediately
- If using any affected Digiever NVR at version ≤ x.x.x.78, upgrade to x.x.x.79 or later. twcert.org.tw
Network Segmentation
- Isolate NVRs in separate VLANs; avoid direct exposure to internet. Use VPN or jump servers for remote access.
Disable Unneeded Services / Ports
- If remote management is enabled, restrict it to trusted IPs. Limit open ports.
Strong Credential Hygiene
- Change any default or reused passwords (for cameras and the NVR device). Use strong, unique credentials.
Monitor Logs & Anomalies
- Look for configuration download attempts, unusual OS command executions, unexpected remote connections.
Use Firewalls / WAF / Access Controls
- Enforce inbound traffic rules – only allow access from known management networks.
Vendor / Patch Management Policy
- Ensure devices are regularly updated; subscribe to vendor CVE / TWCERT advisories.
Regular Security Audit of IoT / Surveillance Infrastructure
- Periodic pen test or vulnerability assessment of all connected/security appliances.

Context & Global Significance

Critical vulnerabilities in surveillance / video recording infrastructure are increasingly targeted: attackers assume such gear is often legacy, misconfigured, poorly patched.
This is not just about digital systems — video feeds correspond to real world; physical security can be compromised.
Regulatory pressure is increasing in many countries for security of IoT / surveillance devices (minimum security standards, mandatory patching, vulnerability disclosure).
Enterprises often overlook surveillance systems in their overall security program (i.e. ICS / OT security).

CyberDudeBivash Recommendations for Organizations

Maintain an asset inventory of surveillance devices and firmware versions.
Build IoT / NVR security standards: require devices to support secure firmware update, restrict default credentials, limit remote administration.
Consider replacing devices from vendors with slow patch cycles.
Apply defense in depth: combining network segmentation, monitoring, patching, and least privilege.
For organizations using video feeds for critical operations, have incident response playbooks for video system compromise.
