An attacker could exploit this vulnerability by sending a crafted UPnP request to an affected device. "This vulnerability is due to improper validation of incoming UPnP traffic.
The vulnerability allows an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition.
VLANs must be pruned to only include those that are required on the remote side of the bridge.įor more information about bridge mode and how to configure a bridge SSID, please refer to our documentation regarding Wireless Client IP Assignment.īy default, a client or device plugged into the Ethernet port of a repeater will gain no network connectivity. Once a bridge SSID has been configured, navigate to Network-wide > Configure > General > Device configuration, find the option to configure Clients wired directly to Meraki APs, and set that option to have clients behave like they are connected to the bridge SSID (as shown below).Cisco announced recently that it would not be releasing software updates for a vulnerability with its Universal Plug-and-Play (UPnP) service in Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. For additional information regarding switch port configuration, please see our MS Port Configuration Guide. This can be done via the Allowed VLANs configuration within the switch port configuration. If an SSID is in use that uses a VLAN ID, the switch port configuration connecting the gateway MR must be configured to allow this traffic. 
Both bridge APs must be configured to broadcast this SSID.At least one bridge-mode SSID must be configured in dashboard (can be an existing SSID used by clients, but must be in bridge mode).In order for repeater APs to share their wireless connection over their Ethernet port, the following requirements must be met:
