CVE-2017-0920

Estado: ModificadaMedia (4.3)—

Las ediciones Community y Enterprise de Gitlab, en versiones anteriores a la 10.1.6, 10.2.6 y 10.3.4, son vulnerables a un problema de omisión de autenticación en el componente Projects::MergeRequests::CreationsController. Esto resulta en que un atacante puede ver todos los nombres de proyecto y sus respectivos espacios de nombre en una instancia de GitLab.

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).
