Assigner: VulnCheck

Description
Ruijie NBR series routers contain an unauthenticated arbitrary file upload vulnerability via /ddi/server/fileupload.php. The endpoint accepts attacker-supplied values in the name and uploadDir parameters and saves the provided multipart file content without adequate validation or sanitization of file type, path, or extension. A remote attacker can upload a crafted PHP file and then access it from the web root, resulting in arbitrary code execution in the context of the web service. Exploitation evidence was observed by the Shadowserver Foundation on 2025-01-14 UTC.

Executive Summary

This vulnerability exists in Ruijie NBR series routers where an unauthenticated attacker can upload arbitrary files via the /ddi/server/fileupload.php endpoint. The endpoint improperly validates the name and uploadDir parameters and does not check the file type, path, or extension. This allows an attacker to upload a crafted PHP file and execute arbitrary code on the router's web service.

Impact Analysis

An attacker exploiting this vulnerability can execute arbitrary code on the affected router remotely without authentication. This can lead to full compromise of the router, allowing the attacker to control network traffic, steal sensitive information, disrupt services, or use the device as a foothold for further attacks.
