NewStart CGSL CORE 5.04 / MAIN 5.04 : dhcp Multiple Vulnerabilities (NS-SA-2019-0021)

high Nessus Plugin ID 127178

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 dhcp packages installed that are affected by multiple vulnerabilities:

 - It was found that the DHCP daemon did not properly clean up closed OMAPI connections in certain cases. A remote attacker able to connect to the OMAPI port could use this flaw to exhaust file descriptors in the DHCP daemon, leading to a denial of service in the OMAPI functionality. (CVE-2017-3144)

 - A command injection flaw was found in the NetworkManager integration script included in the DHCP client packages in Red Hat Enterprise Linux. A malicious DHCP server, or an attacker on the local network able to spoof DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using NetworkManager and configured to obtain network configuration using the DHCP protocol. (CVE-2018-1111)

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 dhcp packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
