CVE-2021-47796

Estado: AplazadaCrítica (9.3)—

Denver SHC-150 Smart Wifi Camera contains a hardcoded telnet credential vulnerability that allows unauthenticated attackers to access a Linux shell. Attackers can connect to port 23 using the default credential to execute arbitrary commands on the camera's operating system.

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.

AV:N sin autenticación permite acceso remoto directo a credencial hardcodeada (CWE-798) en telnet, ejecutando comandos en shell Linux. T1078.001 por acceso con credencial default; T1059 por ejecución de comandos arbitrarios.

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.
