Description

The Secondary Storage System VM discloses its Apache Web Server version number in HTTP headers and error pages. This type of information disclosure can lead to medium vulnerabilities being reported in web vulnerability scanners and reveals the Apache server version unnecessarily.

The apache2 directory structure no longer contains /etc/apache2/conf.d/ in Debian 9 and therefore the appropriate apache2 security configuration file is in another location. The /opt/cloud/bin/setup/common.sh script has not been updated to reflect this.
