Technical Analysis
An unauthorised File Upload (XSS) Vulnerability security flaw has been identified in the web-based management interface of Cisco RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers.
This vulnerability may permit an attacker, who is not authenticated and operates remotely, to upload any file of their choice to a compromised device. The root cause of this vulnerability lies in the inadequacy of authorization enforcement mechanisms related to file uploads.
To exploit this flaw, an attacker could dispatch a meticulously crafted HTTP request to a vulnerable device. A successful exploitation of this vulnerability could empower the attacker to upload unrestricted files to the compromised device.
