CVE-2018-16791

Estado: ModificadaCrítica (9.8)—

In SolarWinds SFTP/SCP Server through 2018-09-10, the configuration file is world readable and writable, and stores user passwords in an insecure manner, allowing an attacker to determine passwords for potentially privileged accounts. This also grants the attacker an ability to backdoor the server.

CVSS

Probabilidad de explotación (EPSS)
