CVE-2025-25427

Estado: AnalizadaAlta (8.6)—

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.

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).
