Symptoms

Apache with NetWorker and NetWorker Management Console (NMC):
  1. How are Apache and Tomcat used by NetWorker?
  2. Which vulnerabilities do exist with the Apache or Tomcat versions used by NetWorker?
  3. Is there any way to upgrade Apache or Tomcat versions on NetWorker?

Cause

Identify which versions of Apache and Tomcat NetWorker is bundled with.

Resolution

Apache is used for hosting a landing site for a Java application that opens the NetWorker Management Console (NMC) authentication at startup. After NMC is launched, Apache is no longer needed or used and NetWorker authentication takes over. Apache is not used by the Client, Storage Node, or NetWorker Server after this point.
 
NetWorker bundles a locked down Apache server that has as few vulnerabilities as possible. NetWorker updates the version of Apache with each major release of NetWorker.

The NetWorker Management Console server uses Embedded Apache server software for only two things:

  • Download of the Console jar files.
  • Start-up of the Console server daemon or service

Below are the different Apache HTTPD versions used by the NetWorker Management Console server:

  • NMC version 19.10.0.0 has Apache httpd 2.4.56
  • NMC version 19.10.0.2 has Apache httpd 2.4.58
  • NMC version 19.11.0.1 has Apache httpd 2.4.59
  • NMC versions 19.10.0.5, 19.11.0.2 and 19.12.0.0 have Apache httpd 2.4.62
  • NMC versions 19.13.0.0 , 19.12.0.1 and 19.11.0.5 have Apache httpd 2.4.63
  • NMC version 19.13.0.2 and 19.14.0.0 has Apache httpd 2.4.65 
  • NMC version 19.14.0.1 and 19.15 will have Apache https 2.4.68

Below are the different Apache Tomcat versions included on a NetWorker (NW) server:

  • NW versions 19.10.0.0 has Apache Tomcat 9.0.76
  • NW versions 19.10.0.1 has Apache tomcat 9.0.82
  • NW versions 19.10.0.3 has Apache tomcat 9.0.85

  • NW version 19.13.0.3 has Apache tomcat 10.1.49
  • NW version 19.14.0.1 has Apache tomcat 10.1.55
  • NW version 19.15 will have Apache tomcat 10.1.57 (or newer)
  • NW version 19.14.0.2 will have Apache tomcat 10.1.59 (or newer)
 
NOTE: These components are embedded inside the NetWorker installation packages. They cannot be upgraded manually. To benefit from an upgraded version, find the NetWorker version that includes the specific component version you want to upgrade to.

Expand the following sections regarding component version validation:

HTTPD Version Validation:

To find your installed HTTPD version on Linux/UNIX, run:

strings /opt/lgtonmc/apache/bin/httpd | grep 'Apache/'

To find your installed HTTPD version on Windows, perform the following:

  • Go to C:\Program Files\EMC NetWorker\Management\GST\apache\bin
  • Hover your cursor over the httpd.exe. The version is shown as seen here:

example of checking httpd version

Apache Tomcat Version Validation:

Determine the Apache version used by NetWorker through the following process:

Linux: 

From an elevated (root) prompt, run: JRE_HOME=/opt/nre/java/latest JAVA_HOME=/opt/nre/java/latest /opt/nsr/authc-server/tomcat/bin/version.sh

Windows:

  1. Ensure JAVA_HOME environment variable is set: echo %JAVA_HOME%
  2. If nothing is returned, open the system properties, and create the environment variable to identify your Java Runtime Environment (JRE) instance:

Create java home variable

  1. If the variable was newly created, you must open a new command prompt to pick up the variable.
  2. Use the cd command to navigate to your NetWorker install folder's ..\nsr\authc-server\tomcat\bin directory. For example: cd "C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\bin"
  3. Run: version.bat
C:\Users\Administrator.NETWORKER>cd C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\bin\
