Summary

BugTracker.NET in all versions contains an unrestricted file upload flaw in its attachment functionality (CWE-434). The application does not validate file extensions, so a user with administrator privileges can change the configuration to store files in a directory accessible through the web interface. An attacker can then upload a malicious ASPX file and execute it on the server, with the privileges of the account used by the web service.
