CVE-2016-1499 owncloud: information disclosure via directory listings
Last modified: 2016-04-25 02:44:08 EDT
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.
Reproducer can be found here:
