Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-6802 is an unrestricted file upload vulnerability in the getFileFromURL method of Marvell QConvergeConsole that permits remote code execution. The flaw stems from insufficient validation of user-supplied input, enabling arbitrary file uploads that can be executed in the context of the SYSTEM account on affected installations. It carries a CVSS 3.0 score of 9.8 and is tracked under CWE-434.
Remote, unauthenticated attackers can exploit the issue over the network to upload and run malicious files, achieving full code execution without any user interaction or credentials. The vulnerability was originally reported as ZDI-CAN-24922.
The Zero Day Initiative advisory at https://www.zerodayinitiative.com/advisories/ZDI-25-464/ provides further details on the issue and any available mitigations or patches. The associated EPSS score has remained flat at 0.0770 with no material increase observed.

Mitigating Controls (NIST 800-53 r5) AI
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.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Hardened configuration baselines can enforce allowed file types and processing rules.
Secure development practices include input validation and file-type restrictions that prevent this weakness.

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