Bugzero contains a flaws that allows a remote cross site scripting attacks.
Those flaws exists because input passed to "msg" parameter in
"query.jsp" and "entryId" parameter in "edit.jsp" isn't properly
sanitised before being returned to the user.
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.

examples :

/bugzero/jsp/query.jsp?msg=[XSS]
/bugzero/jsp/edit.jsp?projectId=&entryId=[XSS]

Solution:
Edit the source code to ensure that input is properly sanitised.
