Alvaro Munoz

Coordinated Disclosure Timeline

Summary

Apache OfBiz is vulnerable to Server-Side Template Injection (SSTI) leading to Remote Code Execution (RCE)

Product

Apache Ofbiz

Tested Version

17.12.01

Details

Server-Side Template Injection on renderLookupField

Untrusted data flows from request.getParameter("_LAST_VIEW_NAME_") to a FreeMarker macro call definition. An attacker with privileges to render any page containing a lookup field will be able to execute arbitrary system commands by sending a payload such as:

https://localhost:8443/ordermgr/control/FindQuote?_LAST_VIEW_NAME_=%22%2F%3E%24%7B%22freemarker.template.utility.Execute%22%3Fnew%28%29%28%22id%22%29%7D%3CFOO

Note that lookup fields are used in multiple modules of the backend application and they require different permissions.
