Cross site request forgery (csrf)

Cross-site request forgery (CSRF) vulnerability in the file manager service (Services/FileService.ashx) in mojoPortal 2.3.4.3 and 2.3.5.1 allows remote attackers to hijack the authentication of administrators for requests that rename arbitrary files, as demonstrated by causing the user.config file to be moved, leading to a denial of service (service stop) and possibly the exposure of sensitive information.
