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

High
← View More Security Advisories

Synopsis

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.

Solution

Tenable has released an updated TenableCore WAS Image (v20180702) to address this issue. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/tenable-io-was-scanner)
