[R1] TenableCore Web Application Scanner v20180702 Fixes Third-party

Severity: High


The TenableCore Web Application Scanner Image v20180328 was found to contain a
command injection flaw in a script included in the bundled DHCP client
(dhclient) package.

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 which is configured to obtain
network configuration using the DHCP protocol.


Tenable has released an updated TenableCore WAS Image (v20180702) to address
this issue. The installation files can be obtained from the Tenable Downloads
Portal (
