CVE-2023-48268

Estado: ModificadaAlta (7.5)—

Mattermost no limita la cantidad de datos extraídos de archivos comprimidos durante la importación de tableros en Mattermost Boards, lo que permite a un atacante consumir recursos excesivos, lo que posiblemente lleve a una denegación de servicio, al importar un tablero usando un zip (bomba zip) especialmente manipulado.

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).
