Xuxueli xxl-job trigger Endpoint XxlJobServiceImpl.java triggerJob server-side request forgery

A weakness has been identified in Xuxueli xxl-job up to 3.3.2. The affected element is the function triggerJob of the file xxl-job-admin/src/main/java/com/xxl/job/admin/service/impl/XxlJobServiceImpl.java of the component trigger Endpoint. This manipulation of the argument addressList causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. There is ongoing doubt regarding the real existence of this vulnerability. The project maintainer explains (translated from Chinese): "Triggers are manually activated and involve login and access control, thus requiring management." The pull request by the researcher got rejected because of that.
