Moodle 1.9.x < 1.9.19 DoS



The remote web server is hosting a web application that is vulnerable to a Denial of Service (DoS) attack vector.


The remote web server hosts Moodle, an open-source course management system. Versions of Moodle 1.9.x prior to 1.9.19 are exposed to a flaw that may allow a remote denial of service. The issue is triggered when searching database activities, which will cause an exhaustion of CPU resources. This will result in loss of availability for the program and the system. (CVE-2012-3398)


Upgrade to Moodle version 1.9.19 or later.
