'Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.'
This issue affects ClearOS 7 and ClearOS 6.
This issue was fixed in the backported fixes of versions of:
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.
If you are running ClearOS 6 or 7, please ensure that you are running the latest updates:
You may also validate your version by running:
rpm -qi httpd
