NewStart CGSL CORE 5.05 / MAIN 5.05 : samba Multiple Vulnerabilities (NS-SA-2023-0016)

high Nessus Plugin ID 174101

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has samba packages installed that are affected by multiple vulnerabilities:

 - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
 (CVE-2016-2124)

 - A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation. (CVE-2020-25717)

 - The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide ...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver. Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

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.
