"According to its version number, the version of eFront running on
the remote web server is affected by multiple vulnerabilities :

  - A path traversal vulnerability exists due to improper
    sanitization of user-supplied input to the 'file'
    parameter of the view_file.php script. A remote attacker
    can exploit this, via a specially crafted request, to
    gain access to arbitrary files and disclose sensitive
    information.

  - Multiple SQL injection vulnerabilities exist due to
    improper sanitization of user-supplied input to the
    'new_less_id' parameter of the new_sidebar.php script. A
    remote attacker can exploit these vulnerabilities to
    manipulate the database.

  - A potential PHP object injection issue exists in the
    copy.php script.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
