Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
The PEAR XML-RPC and phpxmlrpc libraries allow remote attackers to |
| 20 |
execute arbitrary PHP script commands. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations |
| 26 |
of the XML-RPC protocol. |
| 27 |
|
| 28 |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Stefan Esser of the Hardened-PHP Project discovered that the PEAR |
| 44 |
XML-RPC and phpxmlrpc libraries were improperly handling XMLRPC |
| 45 |
requests and responses with malformed nested tags. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A remote attacker could exploit this vulnerability to inject arbitrary |
| 51 |
PHP script code into eval() statements by sending a specially crafted |
| 52 |
XML document to web applications making use of these libraries. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There are no known workarounds at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All PEAR-XML_RPC users should upgrade to the latest available version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=dev-php/PEAR-XML_RPC-1.4.0" |
| 66 |
|
| 67 |
All phpxmlrpc users should upgrade to the latest available version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=dev-php/phpxmlrpc-1.2-r1" |
| 71 |
