XSS in TP-Link TL-WR841N v14/v14.6/v14.8 Upnp page

A stored cross-site scripting (XSS) vulnerability in the upnp.htm page of the web Interface in TP-Link WR841N v14/v14.6/v14.8 <= Build 241230 Rel. 50788n allows remote attackers to inject arbitrary JavaScript code via the port mapping description. This leads to an execution of the JavaScript payload when the upnp page is loaded.

A password-disclosure issue in the web interface on certain TP-Link devices allows a remote attacker to get full administrative access to the web panel. This affects WA901ND devices before 3.16.9(201211) beta, and Archer C5, Archer C7, MR3420, MR6400, WA701ND, WA801ND, WDR3500, WDR3600, WE843N, WR1043ND, WR1045ND, WR740N, WR741ND, WR749N, WR802N, WR840N, WR841HP, WR841N, WR842N, WR842ND, WR845N, WR940N, WR941HP, WR945N, WR949N, and WRD4300 devices.
