In short

A TP-Link TL-WR841N router has a flaw in its web interface (httpd) that allows anyone on the network to access and view stored login credentials without needing to authenticate first. This is dangerous because an attacker can use these credentials to fully control the router.

Technical detail

The httpd service on TCP port 80 implements improper authentication controls (CWE-290), allowing network-adjacent attackers to disclose stored credentials without authentication. The vulnerability requires network access but no prior authentication, and successful exploitation grants access to sensitive authentication information that can be leveraged for complete device compromise.
