[MajorSecurity SA-080]WordPress 3.0.1 - Cross Site Scripting Issue



Product: WordPress 3.0.1

Security-Risk: low

Remote-Exploit: yes

Vendor-URL: http://www.wordpress.org/

Advisory-Status: published



Discovered by: David Vieira-Kurz of MajorSecurity

Affected Products:


WordPress 3.0.1

Prior versions may also be vulnerable



"WordPress is web software you can use to create a beautiful website or blog." - from wordpress.org

More Details


I have discovered some vulnerabilities in WordPress 3.0.1, which can be exploited by malicious people to conduct reflected cross-site scripting attacks. Input passed directly to the "checked[0]" parameter in "wp-admin/plugins.php" when the "action" parameter is set to "delete-selected" is not properly sanitised before being stored and 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.



Web applications should never trust on user generated input and therefore sanatize all input. Edit the source code to ensure that input is properly sanitised.
