Cisco released security updates to address a critical flaw (CVE-2019-1663) in several wireless routers that could be exploited by attackers to remotely execute code on the impacted devices.
The CVE-2019-1663 flaw received a CVSS score of 9.8, the issue resides in the web-based management interface of three router models and is caused by the improper validation of user-supplied data. The web-based management interface can be accessed either through a local LAN connection or via remote management, but experts noticed that the latter feature is disabled by default.
“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.” reads the advisory published by Cisco.
“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,”
The flaw affects all releases of the following Cisco models:
RV110W Wireless-N VPN Firewall
RV130W Wireless-N Multifunction VPN Router
RV215W Wireless-N VPN Router
The tech giant fixed the issue in the following releases:
The vulnerabilities were revealed at the GeekPwn Shanghai conference in October 2018, but experts did not disclose technical details at the time. Cisco credited Yu Zhang and Haoliang Lu at the GeekPwn conference, and T. Shiomitsu of Pen Test Partners LLP for the discovery of the flaw.
