Internal Server Error on upload

Dear Webassist,

I am getting an Internal Server Error on Upload. The permissions are set on the folder are set to 777 and the upload server behavious was working fine. I have been in contact with my host who tell me the error is cause because the upload server behaviour is occuring becuase the upload is righting to a temp directory at the root level which is causing problems.

Here is what I recieved:

[Thu Nov 10 22:58:41 2011] [error] [client 69.16.222.128] ModSecurity: Input
filter: Failed to create temporary file:
/root/tmp/20111110-225841-TrxXIUWnuuEAAFG-LxMAAAAG-request_body-d4Wri7
[hostname "thebodytransformed.com"] [uri "/InnerCircle/daily.php"] [unique_id
"TrxXIUWnuuEAAFG-LxMAAAAG"]

This is what I received as a reply from my host

The important bit there is that your application is trying to write to the
/root/tmp/ subdirectory, typically that would be /tmp or
/home/<user>/public_html/tmp That is probably changed in a configuration file
for the application, I looked and did not find it. Do you know how to change
the path to /tmp?

Is there a way to change the tmp file that the upload server behavior uses so that it is not creating a temp file in the root directly so that it does not throw a security issue.

Many thanks for your help

in the servers php.ini file there is a setting called upload_tmp_dir, this is used to set the temporary directory used when a file is uploaded.

The File Upload behavior uses the upload_tmp_dir that is set in the php.ini file.



from:
ini.core.php

  upload_tmp_dir string

The temporary directory used for storing files when doing file upload. Must be writable by whatever user PHP is running as. If not specified PHP will use the system's default.

If the directory specified here is not writable, PHP falls back to the system default temporary directory. If open_basedir is on, then the system default directory must be allowed for an upload to succeed.
