TP-Link WR840N devices have a buffer overflow via a long Authorization HTTP header.

TP-Link WR840N devices allow remote attackers to cause a denial of service (connectivity loss) via a series of packets with random MAC addresses.

TP-Link Archer C1200 1.13 Build 2018/01/24 rel.52299 EU devices have XSS via the PATH_INFO to the /webpages/data URI.

TP-Link TL-WA850RE Wi-Fi Range Extender with hardware version 5 allows remote attackers to cause a denial of service (reboot) via data/reboot.json.

Stack-based buffer overflow in TP-Link TL-WA850RE Wi-Fi Range Extender with hardware version 5 allows remote authenticated users to cause a denial of service (outage) via a long type parameter to /data/syslog.filter.json.

TP-Link TL-WA850RE Wi-Fi Range Extender with hardware version 5 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the wps_setup_pin parameter to /data/wps.setup.json.

The Ping and Traceroute features on TP-Link TL-WR841N v13 00000001 0.9.1 4.16 v0001.0 Build 180119 Rel.65243n devices allow authenticated blind Command Injection.

TP-Link TL-WR841N v13 00000001 0.9.1 4.16 v0001.0 Build 180119 Rel.65243n devices allow clickjacking.

On TP-Link TL-WR841N v13 00000001 0.9.1 4.16 v0001.0 Build 171019 Rel.55346n devices, all actions in the web interface are affected by bypass of authentication via an HTTP request.

CSRF exists for all actions in the web interface on TP-Link TL-WR841N v13 00000001 0.9.1 4.16 v0001.0 Build 180119 Rel.65243n devices.

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.

/usr/lib/lua/luci/websys.lua on TP-LINK IPC TL-IPC223(P)-6, TL-IPC323K-D, TL-IPC325(KP)-*, and TL-IPC40A-4 devices has a hardcoded zMiVw8Kw0oxKXL0 password.

TP-LINK IPC TL-IPC223(P)-6, TL-IPC323K-D, TL-IPC325(KP)-*, and TL-IPC40A-4 devices allow authenticated remote code execution via crafted JSON data because /usr/lib/lua/luci/torchlight/validator.lua does not block various punctuation characters.

TP-Link EAP Controller and Omada Controller versions 2.5.4_Windows/2.6.0_Windows do not control privileges for usage of the Web API, allowing a low-privilege user to make any request as an Administrator. 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.

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.

Stored Cross-site scripting (XSS) vulnerability in the TP-Link EAP Controller and Omada Controller versions 2.5.4_Windows/2.6.0_Windows allows authenticated attackers to inject arbitrary web script or HTML via the userName parameter in the local user creation functionality. This is fixed in version 2.6.1_Windows.

Stored Cross-site scripting (XSS) vulnerability in the TP-Link EAP Controller and Omada Controller versions 2.5.4_Windows/2.6.0_Windows allows authenticated attackers to inject arbitrary web script or HTML via the implementation of portalPictureUpload functionality. This is fixed in version 2.6.1_Windows.

TP-Link WVR, WAR and ER devices allow remote authenticated administrators to execute arbitrary commands via command injection in the pptphellointerval variable in the pptp_server.lua file.

TP-Link WVR, WAR and ER devices allow remote authenticated administrators to execute arbitrary commands via command injection in the new-time variable in the webfilter.lua file.
