CVE-2021-47762

Estado: AplazadaAlta (8.5)—

HTTPDebuggerPro 9.11 contains an unquoted service path vulnerability that allows local attackers to potentially execute arbitrary code with elevated system privileges. Attackers can exploit the unquoted binary path in the service configuration to inject malicious executables and gain elevated access to the 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.

Vector AV:L (acceso local) + PR:L (requiere privilegios) + VC:H (confidencialidad alta) + VI:H (integridad alta). Ruta de servicio sin comillas permite inyección ejecutable y ejecución de código con privilegios elevados.

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.
