Debido a una validación insuficiente de los parámetros pasados a la API de consultas HTTP heredada, es posible inyectar comandos del sistema operativo manipulados en múltiples parámetros y ejecutar código malicioso en el sistema host de OpenTSDB. Este exploit existe debido a una corrección incompleta que se realizó cuando esta vulnerabilidad se reveló previamente como CVE-2020-35476. La validación mediante expresiones regulares que se implementó para restringir la entrada permitida a la API de consultas no funciona como se pretendía, lo que permite que los comandos manipulados eludan la validación.

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
