4) Description of Vulnerability

Secunia Research has discovered a vulnerability in DokuWiki, which can 
be exploited by malicious people to conduct cross-site scripting 
attacks.

Input passed to the "ns" POST parameter in lib/exe/ajax.php (when 
"call" is set to "medialist" and "do" is set to "media") is not 
properly sanitised within the "tpl_mediaFileList()" function in 
inc/template.php 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.
