Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Flaws in WordPress allow a Denial of Service, the disclosure of user |
| 19 |
metadata and the overwriting of restricted files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
WordPress is a PHP and MySQL based multiuser blogging system. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 www-apps/wordpress < 2.0.5 >= 2.0.5 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
"random" discovered that users can enter serialized objects as strings |
| 38 |
in their profiles that will be harmful when unserialized. "adapter" |
| 39 |
found out that user-edit.php fails to effectively deny non-permitted |
| 40 |
users access to other user's metadata. Additionally, a directory |
| 41 |
traversal vulnerability in the wp-db-backup module was discovered. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
By entering specially crafted strings in his profile, an attacker can |
| 47 |
crash PHP or even the web server running WordPress. Additionally, by |
| 48 |
crafting a simple URL, an attacker can read metadata of any other user, |
| 49 |
regardless of their own permissions. A user with the permission to use |
| 50 |
the database backup plugin can possibly overwrite files he otherwise |
| 51 |
has no access to. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All WordPress users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=www-apps/wordpress-2.0.5" |
| 65 |
