|
This module exploits an OGNL injection vulnerability in Apache Roller < 5.0.2. The
|
|
vulnerability is due to an OGNL injection on the UIAction controller because of an
|
|
insecure usage of the ActionSupport.getText method. This module has been tested
|
|
successfully on Apache Roller 5.0.1 on Ubuntu 10.04.
