Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-38095 is an unrestricted file upload vulnerability in the MFileUploadController class of NETGEAR ProSAFE Network Management System. The flaw stems from insufficient validation of user-supplied data during file uploads and permits remote code execution on affected installations. Although the vulnerability requires authentication, the existing mechanism can be bypassed, enabling an attacker to run arbitrary code in the context of the SYSTEM account. The issue was originally reported as ZDI-CAN-19717 and carries a CVSS 3.1 base score of 8.8.

Remote attackers who can reach the management interface may exploit the weakness to upload malicious files and achieve code execution without valid credentials. Successful exploitation grants full control over the affected system, including the ability to install additional tools, modify data, or pivot within the network.

NETGEAR has published security advisory PSV-2023-0024 addressing this and related issues in ProSAFE Network Management System; the advisory and corresponding Zero Day Initiative report ZDI-23-921 direct administrators to apply the vendor-supplied updates available through the NETGEAR knowledge base. The EPSS score has remained flat at 0.1909 since disclosure, indicating no material increase in observed exploitation interest.

existing authentication mechanism can be bypassed. The specific flaw exists within the MFileUploadController class. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-19717.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
