Incomplete blacklist vulnerability in apps/contacts/import.php and apps/contacts/ajax/uploadimport.php in ownCloud before 4.0.13 and 4.5.8 allows an authenticated remote attacker to upload a .htaccess file and therefore the execution of arbitrary PHP code in a standard Apache installation.
It is recommended that all instances are upgraded to ownCloud Server 4.5.8 or 4.0.13.
The ownCloud team thanks the following people for their research and responsible disclosure of the above advisory:
CPE | Name | Operator | Version |
---|---|---|---|
owncloud server | lt | 4.0.13 | |
owncloud server | lt | 4.5.8 |
