On April 7th, Cisco released a security advisory announcing the discovery of a vulnerability in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers that could allow for an unauthenticated, remote attacker to execute arbitrary and potentially malicious code on affected devices.
This vulnerability is being caused by improper validation of user-supplied input in the web-based management interface. A malicious threat actor could exploit this vulnerability by sending specially designed HTTP requests to a targeted device. A successful exploit would allow the attacker to execute arbitrary code as the root user on the underlying operating system of the affected device.
At this time, Cisco has not released software updates that will address this vulnerability. There are also no known workarounds that address this vulnerability.
