CVE-2021-3275

Estado: ModificadaMedia (6.1)—

Unauthenticated stored cross-site scripting (XSS) exists in multiple TP-Link products including WIFI Routers (Wireless AC routers), Access Points, ADSL + DSL Gateways and Routers, which affects TD-W9977v1, TL-WA801NDv5, TL-WA801Nv6, TL-WA802Nv5, and Archer C3150v2 devices through the improper validation of the hostname. Some of the pages including dhcp.htm, networkMap.htm, dhcpClient.htm, qsEdit.htm, and qsReview.htm and use this vulnerable hostname function (setDefaultHostname()) without sanitization.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
