'Description' => %q{
ManageEngine Eventlog Analyzer from v7 to v9.9 b9002 has two security vulnerabilities that
allow an unauthenticated user to obtain the superuser password of any managed Windows and
AS/400 hosts. This module abuses both vulnerabilities to collect all the available
usernames and passwords. First the agentHandler servlet is abused to get the hostid and
2014-11-13 20:48:23 +00:00
slid of each device (CVE-2014-6038); then these numeric IDs are used to extract usernames
and passwords by abusing the hostdetails servlet (CVE-2014-6039). Note that on version 7,
the TARGETURI has to be prepended with /event.
