A weakness has been identified in o2oa up to 10.0. This affects the function FileAction of the file FileAction.java of the component URL Fetching. Executing a manipulation of the argument fileUrl can lead to server-side request forgery. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
