'Description' => %q{
|
|
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.
|
|
|
|
Note: successful exploitation may not result in a session, and as such,
|
|
on_new_session will never repair the HTTP server, leading to a denial-of-service condition.
