CVE-2021-22484

Estado: AnalizadaAlta (7.5)—

Some Huawei wearables have a vulnerability of not verifying the actual data size when reading data.

Successful exploitation of this vulnerability may cause a server out of memory (OOM).

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/PR:N/UI:N indica explotación remota sin privilegios (T1190). El OOM descrito es denegación de servicio de recursos (T1499.004), activable por lectura de datos sin validación de tamaño.

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.
