CVE-2024-5292 is a vulnerability classified under CWE-427 (Uncontrolled Search Path Element) affecting D-Link Network Assistant version 4.0.0.21. The flaw exists in the DNACore service component, which improperly loads a file from an unsecured or user-controllable location. This insecure loading mechanism allows an attacker who already has the ability to execute low-privileged code on the affected system to escalate their privileges to SYSTEM level. The vulnerability is local, meaning the attacker must have some form of initial access or user-level code execution on the machine. Exploitation involves placing a malicious file in the search path that the DNACore service loads, enabling arbitrary code execution with SYSTEM privileges. This can lead to full system compromise, including unauthorized access to sensitive data, system configuration changes, and disruption of service. The CVSS v3.0 score of 7.3 reflects the high impact on confidentiality, integrity, and availability, with low attack complexity but requiring local privileges and user interaction. Although no public exploits have been reported yet, the vulnerability was assigned by the Zero Day Initiative (ZDI) as ZDI-CAN-21426 and is now published, indicating that it is recognized and may be targeted in the future. The affected product is primarily used in network management environments, making it a critical concern for organizations relying on D-Link Network Assistant for device configuration and monitoring.

The primary impact of CVE-2024-5292 is the potential for local attackers to escalate privileges from a low-privileged user to SYSTEM level, effectively gaining full control over the affected machine. This can lead to unauthorized access to sensitive information, installation of persistent malware, disabling of security controls, and disruption of network management operations. Organizations using D-Link Network Assistant in enterprise or critical infrastructure environments face increased risk of insider threats or attackers leveraging initial footholds to gain complete system control. The vulnerability undermines system integrity and availability, potentially allowing attackers to manipulate network configurations or disrupt device management. Although exploitation requires local access, the widespread use of D-Link products in various countries and sectors means that successful exploitation could facilitate lateral movement within networks, increasing the scope of compromise. The absence of known public exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits following public disclosure.

To mitigate CVE-2024-5292, organizations should first verify if they are running the affected version 4.0.0.21 of D-Link Network Assistant and prioritize upgrading to a patched version once available. In the absence of an official patch, administrators should restrict local user permissions to prevent unauthorized code execution and limit access to systems running the vulnerable software. Employ application whitelisting and endpoint protection solutions to detect and block unauthorized file modifications or suspicious DLL loads related to the DNACore service. Network segmentation can reduce the risk by isolating management workstations from untrusted users. Monitoring and logging of local privilege escalation attempts and unusual DNACore service behavior can provide early detection. Additionally, educating users about the risks of executing untrusted code locally and enforcing the principle of least privilege will reduce the attack surface. Vendors and users should maintain vigilance for updates or advisories from D-Link and security communities regarding patches or exploit developments.
