CVE-2020-13101

Estado: ModificadaAlta (7.5)—

En OASIS Digital Signature Services (DSS) versión 1.0, un atacante puede controlar el resultado de la comprobación (es decir, desencadenar un resultado válido o no válido para una firma válida o no válida) por medio de una firma XML diseñada, cuando es usada la opción InlineXML. Esto supera la expectativa de no repudio.

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).
