Synopsis
The remote device is missing a vendor-supplied security patch.Description
According to its self-reported version, Cisco Small Business RV Series Router Firmware is prior to 1.0.03.18. It is, therefore, affected by a DoS vulnerability in the Secure Sockets Layer (SSL) VPN feature due to a lack of proper validation of HTTP requests. An unauthenticated, remote attacker could exploit this to cause the device to unexpectedly reload, resulting in a DoS condition.Please see the included Cisco BIDs and Cisco Security Advisory for more information.
