Info:  
  
Open source php/mysql fully featured auction script. Perfect for those who  
want to start their own auction site.  
  
Details:  
  
an attacker could inject malicous HTML/JS through a SQL injection flow in  
the adsearch.php. the SQl injection flaw exist in the "maxprice" field (see  
POC I). the SQL  
  
injection attack cannot be elevated, so we leverage the SQL injection to  
trigger an error that would write our malicious HTML/JS to the error log.  
the XSS attack  
  
happens when the admin or any user capable of viewing the error log from the  
ACP.  
  
POC I (SQL injection):  
  
'0') ----> this will trigger the error  
'0') OR (1)=(1 ------> will not trigger error  
  
  
POC II (XSS through SQLi):  
  
  
'0') <script>alert('XSS');</script>
