CVE-2026-0834

Estado: ModificadaAlta (7.2)—

Logic vulnerability in TP-Link Archer C20 v5, 6.0, Archer AX53 v1.0 and TL-WR841N v13 (TDDP module) allows unauthenticated adjacent attackers to execute administrative commands including factory reset and device reboot without credentials. Attackers on the adjacent network can remotely trigger factory resets and reboots without credentials, causing configuration loss and interruption of device availability.

This issue affects Archer C20 v6.0 < V6_251031, Archer C20 v5 <EU_V5_260317 or < US_V5_260419

Archer AX53 v1.0 <

V1_251215

TL-WR841N v13 < 0.9.1 Build 20231120 Rel.62366

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:A (red adyacente) sin autenticación (PR:N, UI:N) → T1210. Factory reset (VA:H) causa pérdida de configuración (T1561.002); reboot fuerza DoS (T1499.004). No hay ejecución de comandos arbitrarios, solo comandos administrativos predefinidos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
