This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when e.g. a malicious calendar is viewed. 2) Input passed to the "file" and "template" parameters within certain action modules (e.g. sendto, nbfile) in gwextranet/scp.dll is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via e.g. directory traversal attacks. SOLUTION: Filter malicious characters and character sequences using a proxy.
