|
- Invalid include function at lib/timesheet.class.php :

|
|
----------------lib/timesheet.class.php-------------------
|
|
...
|
|
include ($inc_dir . "database.inc.php");

|
|
include ($lib_dir . "lib.php");
|
|
include ($lib_dir . "timesheet.lib.php");

|
...
|
|

|
|
|
|
|
|
Input passed to the "inc_dir" and "lib_dir" parameter in lib/timesheet.class.php is not properly verified before being used to include files.

|
This can be exploited to include arbitrary files from local or external resources.

Successful exploitation requires that "register_globals" is enabled.
