Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system.
Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".
Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.
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.
The vulnerability is confirmed in version 2012-01-25a. Prior versions may also be affected.
Update to version 2012-01-25b.
