CVE-2018-11749

Estado: ModificadaCrítica (9.8)—

When users are configured to use startTLS with RBAC LDAP, at login time, the user's credentials are sent via plaintext to the LDAP server. This affects Puppet Enterprise 2018.1.3, 2017.3.9, and 2016.4.14, and is fixed in Puppet Enterprise 2018.1.4, 2017.3.10, and 2016.4.15. It scored an 8.5 CVSS score.

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).
