Detailsinfo

A vulnerability was found in Cisco RV110W Wireless-N VPN Firewall, RV130W Wireless-N Multifunction VPN Router and RV215W Wireless-N VPN Router (Firewall Software) (unknown version). It has been classified as critical. Affected is an unknown code block of the component Web-based Management Interface. The manipulation as part of a HTTP Requests leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device. The vulnerability is due to improper validation of user-supplied data in the web-based management interface. An attacker could exploit this vulnerability by sending malicious HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system of the affected device as a high-privilege user. RV110W Wireless-N VPN Firewall versions prior to 1.2.2.1 are affected. RV130W Wireless-N Multifunction VPN Router versions prior to 1.0.3.45 are affected. RV215W Wireless-N VPN Router versions prior to 1.3.1.1 are affected.

The weakness was disclosed 02/28/2019 as cisco-sa-20190227-rmi-cmd-ex as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability is traded as CVE-2019-1663 since 12/06/2018. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Yu Zhang/Haoliang Lu/T. Shiomitsu/Quentin Kaiser in Ruby/Metasploit and been published 7 months after the advisory. The exploit is shared for download at exploit-db.com. It is declared as highly functional. As 0-day the estimated underground price was around $5k-$25k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 13430 (Cisco RV110W, RV130W, and RV215W Routers Management Interface Remote Command Execution Vulnerability(cisco-sa-20190227-rmi-cmd-ex)).

Upgrading eliminates this vulnerability.
