Title
Insecure Session ID Management Vulnerability in Tenda Wireless Routers
Summary
This vulnerability exists in Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) due to the use of login credentials as the session ID through its web-based administrative interface. A remote attacker could exploit this vulnerability by intercepting network traffic and capturing the session ID during insecure transmission. Successful exploitation of this vulnerability could allow the attacker to hijack an authenticated session and compromise sensitive configuration information on the targeted device.
