This vulnerability exists in Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) due to the transmission of credentials encoded using reversible Base64 encoding through the web-based administrative interface. An attacker on the same network could exploit this vulnerability by intercepting network traffic and capturing the Base64-encoded credentials.

Successful exploitation of this vulnerability could allow the attacker to obtain sensitive information and gain unauthorized access to the targeted device.
