Vuln. Description:
W2B Online Banking contains a flaw that allows a remote cross site scripting
attack. This flaw exists because input passed to "SID" paremeter 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.
Also doing XSS attack test attacker will get full path disclosure.
example:
/?ilang=eng&SID=&[XSS]
+
/?ilang=rus&SID=r0t_LOve_Banking_software_like_this_one!
/?ilang=r0t_LOve_Banking_software_like_this_one!
###############################################
Solution:
Edit the source code to ensure that input is properly sanitised.
