CVE-2018-1000840

Estado: ModificadaMedia (6.5)—

Processing Foundation Processing, en versiones 3.4 y anteriores, contiene una vulnerabilidad XEE (XML External Entity) en la función loadXML() que puede resultar en que un atacante pueda leer archivos arbitrarios y exfiltrar su contenido mediante peticiones HTTP. El ataque parece ser explotable si una víctima emplea Processing para analizar un documento XML 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).
