  Xnami facilitates the creation of an image sharing community. This is
  similar in
  functionality to sites like imgur, ImageShack, et al.
  
  BizLogic xnami 1.0 has XSS via the comment parameter in an addComment
  action to the /media/ajax URI.
  
  At any uploaded media there is a comment system where people can post (also
  anonymous).
  The comment system is vulnerable to XSS attacks. Since it's persistent
  and there is an user login interface, it's possible for attackers to
  steal sessions of users and thus admin(s).
  
  ---------------------------
  ---------------------------
  PoC with mediaId 611 as example:
  
  POST:
  http://{{target}/media/ajax
  
  method: addComment
  comment: "><XSSCODE<
  mediaId 611
  ---------------------------
  ---------------------------
  
  Evil javascript code can be inserted and will be executed when visiting the
  media.
