I imagine this is something you're already aware of, and it may be nothing major. I use Watchful to manage the sites on my server, and after running a Vulnerability Scan, one message came up:
| /administrator/components/com_akeebabackup/tmpl/commontemplates/errorhandler.php | System (reported by PHP) | Possible PHP Injection (Unix command) |
If it's not major issue, just let me know so I can make sure I ignore it.
Thanks for a great product - first thing I install on all my sites!
Nope, this file cannot be used for any kind of injection. This is the error handler. Watchful mistakenly reports it because they see the string “exec”. However, we do not use the PHP function exec(). The string appears in the line defined('_JEXEC') or die(); which protects against direct access to the file and in the PHP configuration variable name max_execution_time (which is output after being properly escaped with htmlentities).
Likewise, we do dump the server superglobals ($_GET, $_POST, $_COOKIE, $_REQUEST) again after passing them through htmlentities to avoid other injection attacks, just like we do with any kind of output.
If Watchful believes otherwise they can tell us what they believe is a PHP injection vulnerability so I can tell them exactly why they are wrong.
