Server Hardening: HTTP TRACE TRACK Methods Allowed – Part1 Apache

HTTP TRACE / TRACK Methods AllowedMany vulnerability scanners will often bring back HTTP TRACE TRACK Methods Allowed against Apache and Microsoft web servers of the older generation. TRACE is usually associated with Apache and TRACK for Microsoft. This has a CVSS score of 4.3 and is a relatively easy fix. Clearly the older generation operating systems should be migrated to a supported platform, both the later distributions of Ubuntu and Microsoft 2012 R2 do not allow these methods to be used. However a simple way to validate this finding is to use telnet to connect to the web server on port 80, once connected you can type something similar to the following for each method. The ‘Host’, ‘TestA’ and ‘TestB’ aren’t needed however if you use some custom text you will be sure to see it echoed back by the web server if trace is enabled.

Tap return twice to send.

Which would look something like the below as you can see the user input was returned, the web server accepting the method:

HTTP Trace enabled on Apache
HTTP Trace enabled on Apache

Remediation:

As I said the HTTP TRACK / TRACE issue is this is relatively straight forward to fix, simple add ‘TraceEnable off’ somewhere in your main Apache config file outside of the vhost configuration.

Once implemented retesting should reveal that the method is not allowed:

after adding 'TraceEnable off' HTTP Trace disabled on Apache

Changing SSL TLS Cipher Suites in Windows and Linux

Changing SSL TLS cipher suites on Windows Server 2012 R2I have added a basic guide for changing SSL TLS cipher suites that Windows Server IIS and Linux Ubuntu Apache2 use. Allowing only secure ciphers to be negotiated between your web server and client is essential. This guide will go through how to change and select the different ciphers for both Windows server 2012 R2 and Ubuntu 14.04 in order to help mitigate some of the vulnerabilities in the SSL/TLS protocols.
