Description Adam Mariš 2016-01-07 15:42:33 UTC 
It was found that ownCloud is vulnerable to information exposure through directory listing. It is possible with a normal user to get information about the complete directory structure and included files of all users. The 'force' parameter in the script (index.php/apps/files/ajax/scan.php) can easily be manipulated, by setting its value to 'true'. This vulnerability can potentially be used for denial-of-service attacks if the selected directory is deep enough, because to index many directories requires high computational effort. In addition, sensitive information from other users is exposed.
