> Key: CLOUDSTACK-10304
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10304
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: SystemVM
> Affects Versions: 4.11.0.0
> Reporter: Julian Gilbert
> Assignee: Rohit Yadav
> Priority: Major
> Fix For: 4.12.0.0, 4.11.1.0

>
> {color:#000000}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.{color}
> {color:#000000}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.{color}
