In TP-Link routers, Archer C5 and WR710N-V1, running the latest available code, when receiving HTTP Basic Authentication the httpd service can be sent a crafted packet that causes a heap overflow. This can result in either a DoS (by crashing the httpd process) or an arbitrary code execution.

In the TP-Link RE365 V1_180213, there is a buffer overflow vulnerability due to the lack of length verification for the USER_AGENT field in /usr/bin/httpd. Attackers who successfully exploit this vulnerability can cause the remote target device to crash or execute arbitrary commands.

The TP-LINK EAP Controller is TP-LINK's software for remotely controlling wireless access point devices. It utilizes a Java remote method invocation (RMI) service for remote control.

Remote attackers can implement deserialization attacks through the RMI protocol. Successful attacks may allow a remote attacker to remotely control the target server and execute Java functions or bytecode.
