CVE-2026-22082
HighSummary
Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) use login credentials as the session ID in the web-based administrative interface. A remote attacker can intercept network traffic and capture the session ID during insecure transmission.
Risk Assessment
Session interception could allow an attacker to hijack an authenticated session and compromise sensitive configuration information on the device.
Recommendation
Secure administrative traffic (e.g., via HTTPS) and consider changing the session mechanism to a more secure one.
Other vulnerabilities in Tenda Wireless Routers
See all- CVE-2026-22081High
Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) lack the HTTPOnly flag for session cookies in the web-based administrative interface. A remote attacker can capture session cookies transmitted over an insecure HTTP connection.
- CVE-2026-22080High
Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) transmit login credentials encoded using reversible Base64 encoding through the web-based administrative interface. An attacker on the same network can intercept traffic and capture the encoded credentials.
- CVE-2026-22079High
Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) transmit login credentials in plaintext during initial login or post-factory reset setup through the web-based administrative interface. An attacker on the same network can intercept traffic and capture the credentials.
Original NVD description (English source)
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.
