This can be exploited to insert arbitrary HTTP headers, which will be included in a response sent to the user. 2) Certain unspecified input related to ExcelTables is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 3) Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 4) An unspecified error exists within the MicrosoftClient.jar Java applet, which can be exploited to download and install a malicious JAR file on client systems. Successful exploitation of this vulnerability allows execution of arbitrary code in context of a client using the gateway. 5) An error when handling session cookies with a NULL value can be exploited to stop the IIS worker process and disrupt Web services.
