vBug Tracker contains a flaws that allows a remote cross site scripting
attacks.
Those flaws exists because input passed to "sortorder" parameter 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.

example :

/vbugs.php?do=list&s=&textsearch=&vbug_typeid
=0&vbug_statusid=0&vbug_severityid=0&vbug_ver
sionid=0&assignment=0&sortfield=lastedit&sort
order=%22%3Cscript%3Ealert('r0t')%3C/script%3E

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