TITLE:
Wordpress Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA15831

VERIFY ADVISORY:
http://secunia.com/advisories/15831/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of system
information, System access

WHERE:
>From remote

SOFTWARE:
Wordpress 1.x
http://secunia.com/product/3978/

DESCRIPTION:
James Bercegay has reported some vulnerabilities in Wordpress, which
can be exploited by malicious people to manipulate mail messages,
conduct cross-site scripting and SQL injection attacks, and by
malicious users to compromise a vulnerable system.

1) Input passed to the "comment" and "p" parameters in "post.php"
isn't properly sanitised before being returned to the user. This can
be exploited to execute arbitrary HTML and script code in an
administrator's browser session in context of an affected site.

2) Some input passed via the XML-RPC interface isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "message" parameter in "wp-login.php" isn't
properly verified before it is used. This can be exploited to
manipulate the message content of the mail sent via the "Forgotten
Password" feature.

Successful exploitation requires that "register_globals" is enabled.

4) An input validation error in the administration section can be
exploited to inject arbitrary PHP code into existing plugins.

Successful exploitation requires administrative privileges.

It is also possible to disclose the full path to certain scripts by
accessing them with invalid input.

The vulnerabilities have been reported in version 1.5.1.2 and prior.

SOLUTION:
Update to version 1.5.1.3.
