CVE-2024-5631 in NVR3608PGE2W
Summary
by MITRE • 07/09/2024
Longse NVR (Network Video Recorder) model NVR3608PGE2W, as well as products based on this device, are transmitting user's login and password to a remote control service without using any encryption. This enables an on-path attacker to eavesdrop the credentials and subsequently obtain access to the video stream. The credentials are being sent when a user decides to change his password in router's portal.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

This vulnerability affects Longse NVR3608PGE2W network video recorder devices and their derivatives, representing a critical security flaw in networked surveillance equipment. The device fails to implement encryption for sensitive credential transmission, creating an inherent weakness in the authentication process. When users attempt to modify their passwords through the router's web interface, the system sends authentication credentials in plaintext to remote control services, exposing them to interception by malicious actors positioned within the network path. This design flaw fundamentally compromises the security model of the device, as it violates basic principles of secure communication protocols and authentication mechanisms.
The technical implementation of this vulnerability stems from the device's failure to utilize encrypted channels for credential transmission. According to CWE-312, this represents a weakness where sensitive data is exposed through inadequate protection mechanisms during transmission. The attack vector is particularly concerning as it requires minimal sophistication from an adversary, merely requiring network interception capabilities to capture the unencrypted credentials. The vulnerability specifically manifests when users interact with the password change functionality, making it exploitable during routine administrative operations. This creates a window of opportunity for attackers to capture credentials and subsequently gain unauthorized access to the video surveillance streams, effectively compromising the entire security infrastructure of the device.
The operational impact of this vulnerability extends beyond simple credential theft, as it enables comprehensive unauthorized access to video surveillance systems. An attacker who successfully intercepts the credentials can gain full control over the NVR device, potentially accessing live video feeds, recorded footage, and administrative controls. This compromise undermines the fundamental security assumptions of networked surveillance systems, as the device's primary function as a security monitoring tool becomes subverted by the vulnerability. The attack surface is further expanded by the fact that this affects not just the specific model but also products based on the same device architecture, indicating a systemic design flaw across multiple units. According to ATT&CK framework, this vulnerability maps to T1071.004 for application layer protocol: DNS and T1566.001 for credential harvesting through network sniffing, highlighting both the network-level exploitation and credential compromise aspects.
Mitigation strategies for this vulnerability must address the fundamental lack of encryption in credential transmission. Immediate remediation involves implementing encrypted communication channels such as TLS for all administrative interfaces and credential handling processes. Device manufacturers should ensure that all authentication data is transmitted through secure channels with proper encryption protocols in place. Network administrators should consider implementing additional security controls such as network segmentation and monitoring for unusual credential-related traffic patterns. The vulnerability also underscores the importance of secure-by-design principles in IoT and security device development, as outlined in NIST SP 800-33 and ISO/IEC 27030 standards. Organizations should conduct regular security assessments of their networked devices and ensure that all communication channels are properly encrypted to prevent similar vulnerabilities from being exploited in the future.
