Cross site request forgery (csrf)

Multiple cross-site request forgery (CSRF) vulnerabilities in Collabtive 0.4.8 allow remote attackers to hijack the authentication of administrators for requests that (1) submit or edit a new project, or (2) upload files to a project, or (3) attach files to messages via unknown vectors. NOTE: these issues can be leveraged with other vulnerabilities to create remote attack vectors that do not require authentication.
