SQL injection vulnerability in managetimetracker.php in Collabtive before 1.2 allows remote authenticated users to execute arbitrary SQL commands via the id parameter in a projectpdf action.

Cross-site scripting (XSS) vulnerability in manageproject.php in Collabtive 0.4.8 allows user-assisted remote attackers to inject arbitrary web script or HTML via the project Name, which is not properly handled when the administrator performs an editform action, related to admin.php.

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.

Unrestricted file upload vulnerability in Collabtive 0.4.8 allows remote authenticated users to execute arbitrary code by uploading a file with an executable extension and using a text/plain MIME type, then accessing it via a direct request to the file in files/, related to (1) the showproject action in managefile.php or (2) the Messages feature.
