A Buffer Overflow vulnerability exists in TP-LINK WR-886N 20190826 2.3.8 in the /cloud_config/router_post/modify_account_pwd feature, which allows malicious users to execute arbitrary code on the system via a crafted post request.

A Buffer Overflow vulnerabilitiy exists in TP-LINK WR-886N 20190826 2.3.8 in the /cloud_config/router_post/register feature, which allows malicious users to execute arbitrary code on the system via a crafted post request.

A Buffer Overflow vulnerabiltiy exists in TP-LINK WR-886N 20190826 2.3.8 in thee /cloud_config/router_post/login feature, which allows malicious users to execute arbitrary code on the system via a crafted post request.

A Buffer Overflow vulnerability exists in TP-LINK WR-886N 20190826 2.3.8 in the /cloud_config/router_post/get_reset_pwd_veirfy_code feature, which allows malicious users to execute arbitrary code on the system via a crafted post request.

A Buffer Overflow vulnerability exists in TP-LINK WR-886N 20190826 2.3.8 in the /cloud_config/router_post/get_reg_verify_code feature, which allows malicious users to execute arbitrary code on the system via a crafted post request.

A Buffer Overflow vulnerability exists in TP-LINK WR-886N 20190826 2.3.8 in /cloud_config/cloud_device/info interface, which allows a malicious user to executee arbitrary code on the system via a crafted post request.

A Buffer Overflow vulnerability exists in TP-LINK WR-886N 20190826 2.3.8 via the /cloud_config/router_post/check_reset_pwd_verify_code interface.

A Buffer Overflow vulnerability exists in TP-LINK WR-886N 20190826 2.3.8 in the /cloud_config/router_post/check_reg_verify_code function which could let a remove malicious user execute arbitrary code via a crafted post request.

TP-Link Omada SDN Software Controller before 5.0.15 does not check if the authentication method specified in a connection request is allowed. An attacker can bypass the captive portal authentication process by using the downgraded "no authentication" method, and access the protected network. For example, the attacker can simply set window.authType=0 in client-side JavaScript.

TP-Link Archer A7 Archer A7(US)_V5_210519 is affected by a command injection vulnerability in /usr/bin/tddp. The vulnerability is caused by the program taking part of the received data packet as part of the command. This will cause an attacker to execute arbitrary commands on the router.

The PING function on the TP-Link TL-WR840N EU v5 router with firmware through TL-WR840N(EU)_V5_171211 is vulnerable to remote code execution via a crafted payload in an IP address input field.

A misconfiguration in HTTP/1.0 and HTTP/1.1 of the web interface in TP-Link AX10v1 before V1_211117 allows a remote unauthenticated attacker to send a specially crafted HTTP request and receive a misconfigured HTTP/0.9 response, potentially leading into a cache poisoning attack.

An HTTP request smuggling attack in TP-Link AX10v1 before v1_211117 allows a remote unauthenticated attacker to DoS the web application via sending a specific HTTP packet.

A denial-of-service attack in WPA2, and WPA3-SAE authentication methods in TP-Link AX10v1 before V1_211014, allows a remote unauthenticated attacker to disconnect an already connected wireless client via sending with a wireless adapter specific spoofed authentication frames

Unauthenticated stored cross-site scripting (XSS) exists in multiple TP-Link products including WIFI Routers (Wireless AC routers), Access Points, ADSL + DSL Gateways and Routers, which affects TD-W9977v1, TL-WA801NDv5, TL-WA801Nv6, TL-WA802Nv5, and Archer C3150v2 devices through the improper validation of the hostname. Some of the pages including dhcp.htm, networkMap.htm, dhcpClient.htm, qsEdit.htm, and qsReview.htm and use this vulnerable hostname function (setDefaultHostname()) without sanitization.
