Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
A vulnerability when handling database input in PEAR::MDB2 allows |
| 22 |
remote attackers to obtain sensitive information. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
PEAR::MDB2 is a database abstraction layer for PHP aimed to provide a |
| 28 |
common API for all supported relational database management systems. A |
| 29 |
LOB ("large object") is a database field holding binary data. |
| 30 |
|
| 31 |
Affected packages |
| 32 |
================= |
| 33 |
|
| 34 |
------------------------------------------------------------------- |
| 35 |
Package / Vulnerable / Unaffected |
| 36 |
------------------------------------------------------------------- |
| 37 |
1 dev-php/PEAR-MDB2 < 2.5.0_alpha1 >= 2.5.0_alpha1 |
| 38 |
|
| 39 |
Description |
| 40 |
=========== |
| 41 |
|
| 42 |
priyadi discovered that the request to store a URL string as a LOB is |
| 43 |
treated as a request to retrieve and store the contents of the URL. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
If an application using PEAR::MDB2 allows input of LOB values via a web |
| 49 |
form, remote attackers could use the application as an indirect proxy |
| 50 |
or obtain sensitive information, including "file://" URLs local to the |
| 51 |
web server. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
As a workaround, manually filter input before storing it as a LOB in |
| 57 |
PEAR::MDB2. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All PEAR::MDB2 users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=dev-php/PEAR-MDB2-2.5.0_alpha1" |
| 66 |
