CVE-2018-3739

Estado: ModificadaCrítica (9.1)—

https-proxy-agent en versiones anteriores a la 2.1.1 pasa la opción auth al constructor del búfer sin un saneamiento adecuado, lo que resulta en una denegación de servicio (DoS) y una fuga de memoria no inicializada en setups en donde un atacante podría enviar entradas tecleadas en el parámetro "auth" (p.ej., JSON).

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).
