2015-09-16 16:41:23 +00:00
This module exploits a default credential vulnerability in ManageEngine OpManager, where a
default hidden account "IntegrationUser" with administrator privileges exists. The account
has a default password of "plugin" which can not be reset through the user interface. By
log-in and abusing the default administrator's SQL query functionality, it's possible to
write a WAR payload to disk and trigger an automatic deployment of this payload. This
module has been tested successfully on OpManager v11.5 and v11.6 for Windows.
