CVE-2024-5947 in DSE855
Summary
by MITRE • 06/13/2024
Deep Sea Electronics DSE855 Configuration Backup Missing Authentication Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Deep Sea Electronics DSE855 devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the web-based UI. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-22679.

The CVE-2024-5947 vulnerability represents a critical security flaw in Deep Sea Electronics DSE855 network devices that exposes sensitive configuration data through improper access controls. This vulnerability resides within the device's web-based user interface and demonstrates a fundamental failure in authentication mechanisms that allows unauthenticated access to critical system information. The flaw specifically affects installations where the web management interface is accessible to network-adjacent attackers, creating a significant risk surface for malicious actors who can exploit this weakness without requiring any credentials or prior authentication.
The technical implementation of this vulnerability stems from the absence of proper authentication checks before exposing sensitive configuration data through the web interface. This design flaw aligns with CWE-287, which addresses improper authentication issues in software systems. The vulnerability specifically targets the configuration backup functionality where stored credentials and system parameters are accessible without any form of user authentication or authorization verification. Attackers can leverage this weakness to gain unauthorized access to sensitive information including but not limited to administrative credentials, network configurations, and system settings that could facilitate further exploitation.
From an operational perspective, this vulnerability presents a severe risk to organizations deploying DSE855 devices in their network infrastructure. The lack of authentication requirements means that any attacker within the network segment can potentially access critical system information and stored credentials. This vulnerability enables attackers to escalate their privileges and move laterally within the network, as the disclosed information could include administrative accounts, network service credentials, and other sensitive data that could be used for persistent access or additional attacks. The impact extends beyond immediate credential disclosure to potentially enable complete system compromise and unauthorized network access.
The security implications of CVE-2024-5947 align with ATT&CK technique T1078 which covers valid accounts and T1566 which addresses credential harvesting. Organizations should implement immediate mitigations including network segmentation to restrict access to these devices, disabling unnecessary web interfaces, and implementing proper access controls. The vulnerability demonstrates the importance of following security best practices such as principle of least privilege and defense in depth. Network administrators should also consider implementing intrusion detection systems to monitor for suspicious access patterns and ensure that all devices are running the latest firmware versions that address this specific vulnerability. Additionally, organizations should conduct comprehensive security assessments to identify other potentially affected devices and implement proper monitoring protocols to detect unauthorized access attempts to critical network infrastructure components.
This vulnerability highlights the critical need for robust authentication mechanisms in network devices and demonstrates how seemingly minor implementation flaws can lead to significant security breaches. The absence of authentication checks in configuration backup functions represents a design flaw that violates fundamental security principles and creates an exploitable attack surface that can be leveraged by threat actors to gain unauthorized access to sensitive network information and potentially compromise entire network infrastructures.
