CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
WordPress 2.x
http://secunia.com/product/6745/

DESCRIPTION:
Two vulnerabilities have been reported in WordPress, which can be
exploited by malicious people to conduct cross-site scripting
attacks, bypass certain security restrictions, and to compromise a
vulnerable system.

1) A vulnerability is caused due to improper access restriction of
the administration section. This can be exploited to bypass the
authentication mechanism and gain administrative access by setting a
specially crafted cookie. This can further be exploited to execute
arbitrary PHP code.

Successful exploitation of this vulnerability requires that
registering new accounts is enabled.

The vulnerability is reported in version 2.5.

2) Input passed to an unspecified parameter is not properly sanitised
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

The vulnerability is reported in version 2.5. Prior versions may also
be affected.

SOLUTION:
Update to version 2.5.1.
