CVE-2026-78577

Estado: AplazadaMedia (5.3)—

Tapo C120 v1 and C200 V5 contain a vulnerability in the HTTPS onboarding scan function due to missing authentication. After initial setup, an unauthenticated attacker on the same local network can invoke the scan action and retrieve nearby wireless access-point metadata, including SSIDs, BSSIDs, authentication and encryption modes, and signal-strength information.

Successful exploitation may disclose information about the wireless environment surrounding the camera, allowing an attacker to learn elements of the local wireless topology.

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.

Función HTTPS sin autenticación en red local permite obtener metadatos de redes inalámbricas (SSIDs, BSSIDs, modos de seguridad) sin credenciales, revelando información de infraestructura.

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.
