CVE-2018-1000406

Estado: ModificadaMedia (6.5)—

Una vulnerabilidad de salto de directorio existe en Jenkins, en sus versiones 2.145 y anteriores LTS 2.138.1 y anteriores, en core/src/main/java/hudson/model/FileParameterValue.java que permite a los atacantes con permisos de "Job/Configure" para definir un parámetro de archivo con un nombre de archivo fuera del directorio intencionado, conduciendo a la escritura de archivos arbitrarios en el maestro de Jenkins cuando se programa un build.

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).
