CVE 2016-8743

/** * This is the notes section. CVE documents should ONLY be created by employees of ClearCenter with the authority to make statements on behalf of the company. If you have content that would be useful to the statement, please contact ClearCenter. */

'Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution.'

ClearCenter response

This issue affects ClearOS 7 and ClearOS 6.

Short response

This issue was fixed in the backported fixes of versions of:

  • httpd version 2.4.6-45 and later in ClearOS 7
  • webconfig-httpd version 2.4.6-45 and later in ClearOS 7
  • httpd version 2.2.15-60 or later in ClearOS 6
  • webconfig-httpd version 2.2.15-60 or later in ClearOS 6

Long response

This issue was fixed during the maintenance cycle of ClearOS 7 and 6. ClearOS systems that are up to date do not suffer from this vulnerability. Some vulnerability scanning software may report this bug because their only method for determining the issue is to check the http version number since the exploit requires specific web configurations and has not other means for testing vulnerability. In ClearOS, version numbers stay consistent through the product's life-cycle and will produce a false positive on this issue if the testing software considers only the http version and not the ClearOS patch level.

Resolution

If you are running ClearOS 6 or 7, please ensure that you are running the latest updates:

yum update

You may also validate your version by running:

rpm -qi httpd

You should validate that you are running:

ClearOS 7
  • httpd version 2.4.6-45 or later
  • webconfig-httpd version 2.4.6-45 or later
ClearOS 6
  • httpd version 2.2.15-60 or later
  • webconfig-httpd version 2.2.15-60 or later
