TP-Link Archer C3200 V1 and Archer C2 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.)Show less

TP-Link Archer C3200 V1 and Archer C2 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.Show less

TP-Link Archer C3200 V1 and Archer C2 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.Show less

CMD_SET_CONFIG_COUNTRY in the TP-Link Device Debug protocol in TP-Link Archer C1200 1.0.0 Build 20180502 rel.45702 and earlier is prone to a stack-based buffer overflow, which allows a remote attacker to achieve code execution or denial of service by sending a crafted payload to the listening server.Show less

CMD_FTEST_CONFIG in the TP-Link Device Debug protocol in TP-Link Wireless Router Archer Router version 1.0.0 Build 20180502 rel.45702 (EU) and earlier is prone to a stack-based buffer overflow, which allows a remote attacker to achieve code execution or denial of service by sending a crafted payload to the listening server.Show less

An issue was discovered on TP-Link TL-WR1043ND V2 devices. The credentials can be easily decoded and cracked by brute-force, WordList, or Rainbow Table attacks. Specifically, credentials in the "Authorization" cookie are encoded with URL encoding and base64, leading to easy decoding. Also, the username is cleartext, and the password is hashed with the MD5 algorithm (after decoding of the URL encoded string with base64).Show less

An issue was discovered on TP-Link TL-WR1043ND V2 devices. An attacker can send a cookie in an HTTP authentication packet to the router management web interface, and fully control the router without knowledge of the credentials.Show less

TP-Link TL-WR940N is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the ipAddrDispose function. By sending specially crafted ICMP echo request packets, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.Show less

TP-Link TL-WR840N v5 00000005 devices allow XSS via the network name. The attacker must log into the router by breaking the password and going to the admin login page by THC-HYDRA to get the network name. With an XSS payload, the network name changed automatically and the internet connection was disconnected. All the users become disconnected from the internet.Show less

TP-Link Archer CR-700 1.0.6 devices have an XSS vulnerability that can be introduced into the admin account through a DHCP request, allowing the attacker to steal the cookie information, which contains the base64 encoded username and password.Show less

The ping feature in the Diagnostic functionality on TP-LINK WR840N v2 Firmware 3.16.9 Build 150701 Rel.51516n devices allows remote attackers to cause a denial of service (HTTP service termination) by modifying the packet size to be higher than the UI limit of 1472.Show less

TP-Link WDR Series devices through firmware v3 (such as TL-WDR5620 V3.0) are affected by command injection (after login) leading to remote code execution, because shell metacharacters can be included in the weather get_weather_observe citycode field.Show less
