CVE-2024-56528

Estado: AnalizadaAlta (7.5)—

This vulnerability affects Snowplow Collector 3.x before 3.3.0 (unless it’s set up behind a reverse proxy that establishes payload limits). It involves sending very large payloads to the Collector and can render it unresponsive to the rest of the requests. As a result, data would not enter the pipeline and would be potentially lost.

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.

Acceso a red sin autenticación (AV:N/PR:N/UI:N) contra aplicación expuesta. Envío de payloads grandes causa negación de servicio por agotamiento de recursos.

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.
