Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in phpMyAdmin might allow remote attackers to bypass |
| 19 |
authentication. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
phpMyAdmin is a web-based management tool for MySQL databases. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 dev-db/phpmyadmin < 4.0.10.20 >= 4.0.10.20 |
| 33 |
< 4.7.0 >= 4.7.0 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
A vulnerability was discovered where the restrictions caused by |
| 39 |
"$cfg['Servers'][$i]['AllowNoPassword'] = false" are bypassed under |
| 40 |
certain PHP versions. This can lead compromised user accounts, who have |
| 41 |
no passwords set, even if the administrator has set |
| 42 |
"$cfg['Servers'][$i]['AllowNoPassword']" to false (which is the |
| 43 |
default). |
| 44 |
|
| 45 |
This behavior depends on the PHP version used (it seems PHP 5 is |
| 46 |
affected, while PHP 7.0 is not). |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker, who only needs to know the username, could bypass |
| 52 |
security restrictions and access phpMyAdmin. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
Set a password for all users. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All phpMyAdmin 4.0.x users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot -v ">=dev-db/phpmyadmin-4.0.10.20:4.0.10.20" |
| 66 |
|
| 67 |
All other phpMyAdmin users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=dev-db/phpmyadmin-4.7.0:4.7.0" |
| 71 |
