Estado: AnalizadaCrítica (9.8)—

Sourcecodester Covid-19 Contact Tracing System 1.0 is vulnerable to RCE (Remote Code Execution). The application receives a reverse shell (php) into imagem of the user enabling RCE.

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 CVSS con AV:N, PR:N, UI:N indica vulnerabilidad remota sin autenticación ni interacción: T1190. El archivo de imagen preparado permite ejecutar código PHP (web shell) en el servidor, confirmado por descripción de RCE. Impactos: T1505.003 (web shell PHP) y T1059 (ejecución de comandos vía reve

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.
