Confluent Kafka Python client's HashiCorp Vault KMS integration could allow a remote attacker to obtain sensitive information due to improper TLS certificate validation.

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:N/PR:N permite T1190. CWE-295 (improper TLS validation) y Vault KMS compromise se logran mediante ataque MITM (T1557). El impacto es lectura de secretos/credenciales (T1005) almacenados en Vault.

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.
