The firmware of EDIMAX IC-3140W Version 3.11 is hardcoded with Administrator username and password.

EDIMAX Technology Co., Ltd. HD Wireless Day & Night Network Camera IC-3140W - Hard-coded password

The default administrator account & password of the EDIMAX wireless network camera is hard-coded. Remote attackers can disassemble firmware to obtain the privileged permission and further control the devices.

A stack-based buffer-overflow exists in Edimax IP-Camera IC-3116W (v3.06) and IC-3140W (v3.07), which allows an unauthenticated, unauthorized attacker to perform remote-code-execution due to a crafted GET-Request. The overflow occurs in binary ipcam_cgi due to a missing type check in function doGetSysteminfo(). This has been fixed in version: IC-3116W v3.08.

Edimax BR-6208AC V1 devices have Insufficient Compartmentalization between a host network and a guest network that are established by the same device. They forward ARP requests, which are sent as broadcast packets, between the host and the guest networks. To use this leakage as a direct covert channel, the sender can trivially issue an ARP request to an arbitrary computer on the network. (In general, some routers restrict ARP forwarding only to requests destined for the network's subnet mask, but these routers did not restrict this traffic in any way. Depending on this factor, one must use either the lower 8 bits of the IP address, or the entire 32 bits, as the data payload.)

Edimax BR-6208AC V1 devices have Insufficient Compartmentalization between a host network and a guest network that are established by the same device. In order to transfer data from the host network to the guest network, the sender joins and then leaves an IGMP group. After it leaves, the router (following the IGMP protocol) creates an IGMP Membership Query packet with the Group IP and sends it to both the Host and the Guest networks. The data is transferred within the Group IP field, which is completely controlled by the sender.

Edimax BR-6208AC V1 devices have Insufficient Compartmentalization between a host network and a guest network that are established by the same device. A DHCP Request is sent to the router with a certain Transaction ID field. Following the DHCP protocol, the router responds with an ACK or NAK message. Studying the NAK case revealed that the router erroneously sends the NAK to both Host and Guest networks with the same Transaction ID as found in the DHCP Request. This allows encoding of data to be sent cross-router into the 32-bit Transaction ID field.

An issue was discovered on EDIMAX IC-3140W through 3.06, IC-5150W through 3.09, and IC-6220DC through 3.06 devices. The ipcam_cgi binary contains a stack-based buffer overflow that is possible to trigger from a remote unauthenticated /camera-cgi/public/getsysyeminfo.cgi?action=VALUE_HERE HTTP request: if the VALUE_HERE length is more than 0x400 (1024), it is possible to overwrite other values located on the stack due to an incorrect use of the strcpy() function.

An issue was discovered in Edimax EW-7438RPn Mini v2 before version 1.26. There is XSS in an SSID field.

Edimax Wi-Fi Extender devices allow goform/formwlencryptvxd CSRF with resultant PSK key disclosure.

Edimax IC-6220DC/IC-5150W ipcam_cgi cgiFormString command injection

A vulnerability was found in Edimax IC-6220DC and IC-5150W up to 3.06. It has been rated as critical. Affected by this issue is the function cgiFormString of the file ipcam_cgi. The manipulation of the argument host leads to command injection. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
