Multiple vulnerabilities in the web-based management interface of Cisco RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an authenticated, remote attacker to execute arbitrary code with elevated privileges equivalent to the web service process on an affected device. These vulnerabilities exist because HTTP requests are not properly validated. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the web-based management interface of an affected device. A successful exploit could allow the attacker to remotely execute arbitrary code on the device.

AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Cisco RV340 routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of the fileparam parameter provided to the upload.cgi endpoint. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the www-data user.
