  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>
