NewStart CGSL MAIN 6.02 : samba Multiple Vulnerabilities (NS-SA-2022-0058)

medium Nessus Plugin ID 160772

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has samba packages installed that are affected by multiple vulnerabilities:

 - A flaw was found in the way samba handled file and directory permissions. An authenticated user could use this flaw to gain access to certain file and directory information which otherwise would be unavailable to the attacker. (CVE-2020-14318)

 - A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before 4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of service. (CVE-2020-14323)

 - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL samba packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
