Wordpress Multiple Vulnerabilities

[niall]

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.
