Synopsis |
16 |
======== |
17 |
|
18 |

20 |
|
21 |

Description |
35 |
=========== |
36 |
|
37 |
girex reported that data from the "config_cascade" parameter in |
38 |
inc/init.php is not properly sanitized before being used. |
39 |
|
40 |
Impact |
41 |
====== |
42 |
|
43 |
A remote attacker could exploit this vulnerability to execute PHP code |
44 |
from arbitrary local, or, when the used PHP version supports ftp:// |
45 |
URLs, also from remote files via FTP. Furthermore, it is possible to |
46 |
disclose the contents of local files. NOTE: Successful exploitation |
47 |
requires the PHP option "register_globals" to be enabled. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
Disable "register_globals" in php.ini. |
53 |
|
54 |
Resolution |
55 |
========== |
56 |
|
57 |
All DokuWiki users should upgrade to the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --ask --oneshot --verbose =www-apps/dokuwiki-2009-02-14b |
