Error when logging into Web Player: "A potentially dangerous Request. Form value was detected from the client."

Product: TIBCO Spotfire Web Player (incl. Consumer and Business Author)

Version: 5.0, 5.5, 6.0, 6.5, 7.0
--------------------
For a Web Player login page, there is the Username and Password text field to allow the users to input text. If the username or password contains the special character "<" in="in" the="the" string,="string," string="string" does="does" not="not" validate="validate" and="and" .net=".Net" framework="framework" throws="throws" an="an" error.="error." this="This" issue="issue" is="is" fixed="fixed" spotfire="Spotfire" version="version" 7.5="7.5" you="you" are="are" allowed="allowed" to="to" have="have" passwords="passwords" containing="containing" both="both"><" and="and">" characters.

Example errors:

• A potentially dangerous Request.Form value was detected from the client (ctl00$contentxxxNameTextBox="<ad").><span=""></span=""></ad").><>

• A potentially dangerous Request.Form value was detected from the client (ctl00$content$passwordTextBox="<dafdafs").><span=""></span=""></dafdafs").><>

The reason for this error is a security precaution, to prevent HTML or even scripts from affecting the form.

It is currently not possible to use "<" or="or">" characters in passwords. In order to be able to login, the user must change the password so it does not contain these characters.
Alternatively, you can upgrade to TIBCO Spotfire version 7.5 which does allow passwords containing both "<" and="and">" characters.
