New! Plugin Severity Now Using CVSS v3

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the samba packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon Elevation of Privilege Vulnerability'.(CVE-2020-1472)
