Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has samba packages installed that are affected by multiple vulnerabilities:

 - A null pointer dereference flaw was found in Samba RPC external printer service. An attacker could use this flaw to cause the printer spooler service to crash.
 (CVE-2018-1050)

 - A flaw was found in the way samba allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client.
 (CVE-2018-1139)

 - A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client.
 (CVE-2018-10858)

Note that Nessus has not tested for this issue 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.
