CVE-2018-11142
This restriction can be bypassed by modifying the 'Host' and 'X_Forwarded_For' HTTP headers in a POST request.
Does this matter?
Lower severity and a low EPSS score (0.42%). Track it; it rarely justifies an emergency change on its own.
Description
The 'systemui/settings_network.php' and 'systemui/settings_patching.php' scripts in the Quest KACE System Management Appliance 8.0.318 are accessible only from localhost. This restriction can be bypassed by modifying the 'Host' and 'X_Forwarded_For' HTTP headers in a POST request. An anonymous user can abuse this vulnerability to execute critical functions without authorization.
