Tp-Link: Security Vulnerabilities
An issue was discovered on TP-Link TL-WR840N v5 00000005 0.9.1 3.16 v0001.0 Build 170608 Rel.58696n and TL-WR841N v13 00000013 0.9.1 4.16 v0001.0 Build 170622 Rel.64334n devices. This issue is caused by improper session handling on the /cgi/ folder or a /cgi file. If an attacker sends a header of "Referer: http://192.168.0.1/mainFrame.htm" then no authentication is required for any action.

The web management interface in the TP-Link EAP Controller and Omada Controller versions 2.5.4_Windows/2.6.0_Windows does not have Anti-CSRF tokens in any forms. This would allow an attacker to submit authenticated requests when an authenticated user browses an attack-controlled domain. This is fixed in version 2.6.1_Windows.

The web application backup file in the TP-Link EAP Controller and Omada Controller versions 2.5.4_Windows/2.6.0_Windows is encrypted with a hard-coded cryptographic key, so anyone who knows that key and the algorithm can decrypt it. A low-privilege user could decrypt and modify the backup file in order to elevate their privileges. This is fixed in version 2.6.1_Windows.
