OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, the application’s BasePage registers an AJAX event listener (AbstractPostAjaxBehavior
) in all pages other than the login page. This listener decodes and deserializes the data
query parameter. We can access this listener by submitting a POST request to any page. This issue may lead to post-auth RCE
This endpoint is subject to authentication and, therefore, requires a valid user to carry on the attack. This issue was addressed in 4.0.3 by encrypting serialization payload with secrets only known to server.
