CVE-2019-17633

Estado: ModificadaAlta (8.8)—

For Eclipse Che versions 6.16 to 7.3.0, with both authentication and TLS disabled, visiting a malicious web site could trigger the start of an arbitrary Che workspace. Che with no authentication and no TLS is not usually deployed on a public network but is often used for local installations (e.g. on personal laptops). In that case, even if the Che API is not exposed externally, some javascript running in the local browser is able to send requests to it.

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).
