Description

ACS Blog contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the [link], [mail], and [img] BBcode tags upon submission to the comments section of ACS Blog. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity. The pages affected by the flaw are: add_comment.asp, admin_entry.asp, inc_editor_buttons_safari.asp, inc_functions.asp, inc_javascripts.js, popup_insert_element.asp, popup_preview.asp, user_footer.asp, user_functions.asp.
