CVE-2019-15060 1 Tp-link 2 Tl-wr840n, Tl-wr840n Firmware 2024-02-04 6.5 MEDIUM 8.8 HIGH
The traceroute function on the TP-Link TL-WR840N v4 router with firmware through 0.9.1 3.16 is vulnerable to remote code execution via a crafted payload in an IP address input field.
CVE-2019-12195 1 Tp-link 2 Tl-wr840n, Tl-wr840n Firmware 2024-02-04 3.5 LOW 4.8 MEDIUM
TP-Link TL-WR840N v5 00000005 devices allow XSS via the network name. The attacker must log into the router by breaking the password and going to the admin login page by THC-HYDRA to get the network name. With an XSS payload, the network name changed automatically and the internet connection was disconnected. All the users become disconnected from the internet.
CVE-2018-15172 1 Tp-link 2 Tl-wr840n, Tl-wr840n Firmware 2024-02-04 5.0 MEDIUM 7.5 HIGH

CVE-2018-11714 1 Tp-link 4 Tl-wr840n, Tl-wr840n Firmware, Tl-wr841n and 1 more 2024-02-04 10.0 HIGH 9.8 CRITICAL
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.
