Weakness (CWE)

CWE-616: Incomplete Identification of Uploaded File Variables (PHP)

Variant Incomplete

The PHP application uses an old method for processing uploaded files by referencing the four global variables that are set for each file (e.g. $varname, $varname_size, $varname_name, $varname_type).

How to prevent it (3 mitigations)

  1. Architecture and Design

    Use PHP 4 or later.

  2. Architecture and Design

    If you must support older PHP versions, write your own version of is_uploaded_file() and run it against $HTTP_POST_FILES['userfile']))

  3. Implementation

    For later PHP versions, reference uploaded files using the $HTTP_POST_FILES or $_FILES variables, and use is_uploaded_file() or move_uploaded_file() to ensure that you are dealing with an uploaded file.
