'The ap_some_auth_required function in server/request.c in the Apache HTTP Server 2.4.x before 2.4.14 does not consider that a Require directive may be associated with an authorization setting rather than an authentication setting, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging the presence of a module that relies on the 2.2 API behavior.'
This issue affects ClearOS 7 but does not affect any version of ClearOS 6.
This issue was fixed in the backported fixes of versions of:
- httpd version 2.4.6-31 and later in ClearOS 7
- webconfig-httpd version 2.4.6-31 and later in ClearOS 7
This issue was fixed during the maintenance cycle of ClearOS 7. No version of ClearOS 6 has ever been affected by this vulnerability. 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.
If you are running ClearOS 7, please ensure that you are running the latest updates:
You may also validate your version by running:
rpm -qi httpd
You should validate that you are running:
- httpd version 2.4.6-31 or later
- webconfig-httpd version 2.4.6-31 or later
