A buffer overflow in the httpd daemon on TP-Link TL-WR841N V12 (firmware version 3.16.9) devices allows an authenticated remote attacker to execute arbitrary code via a GET request to the page for the System Tools of the Wi-Fi network. This affects TL-WR841 V12 TL-WR841N(EU)V12160624 and TL-WR841 V11 TL-WR841N(EU)V11160325 , TL-WR841NV11150616 and TL-WR841 V10 TL-WR841NV10150310 are also affected.

TP-Link TL-WR841N contains an authentication bypass by spoofing vulnerability within the httpd service, which listens on TCP port 80 by default, leading to the disclose of stored credentials. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
