Description Vincent Danen 2011-02-02 21:47:05 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2011-0740 to
the following vulnerability:

Name: CVE-2011-0740
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-0740
Assigned: 20110201
Reference: http://www.autosectools.com/Advisories/WordPress.RSS.Feed.Reader.for.WordPress.0.1_Reflected.Cross-site.Scripting_82.html
Reference: http://www.securityfocus.com/bid/45997
Reference: http://osvdb.org/70644
Reference: http://secunia.com/advisories/43071
Reference: http://xforce.iss.net/xforce/xfdb/64949

Cross-site scripting (XSS) vulnerability in
magpie/scripts/magpie_slashbox.php in RSS Feed Reader 0.1 for
WordPress allows remote attackers to inject arbitrary web script or
HTML via the rss_url parameter.


Note that this wordpress plugin is not shipped, but seems to be using the same magpierss that we ship.  At any rate I've verified the XSS in magpierss 0.72.  To fix this, the following should work:

6 $url = htmlspecialchars($_GET['rss_url']);

(using htmlspecialchars()).  I've not looked to see if there are any other similar occurances.  I don't expect upstream to fix anything as 0.72 was released in 2005 and that is the latest version.
