CVE-2026-22081
HighSummary
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.
Risk Assessment
Capturing session cookies could allow an attacker to obtain sensitive information and gain unauthorized access to the device.
Recommendation
Set the HTTPOnly flag for session cookies and use encrypted connections (HTTPS) for the administrative interface.
Other vulnerabilities in Tenda Wireless Routers
See all- CVE-2026-22082High
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.
- 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 missing HTTPOnly flag for session cookies associated with the web-based administrative interface. A remote at-tacker could exploit this vulnerability by capturing session cookies transmitted over an insecure HTTP connection. Successful exploitation of this vulnerability could allow the attacker to obtain sensitive information and gain unau-thorized access to the targeted device.
