<div><p>WebSphere<sup>®</sup> Portal
|
||
|
|
enables Cross-site scripting (CSS) security protection by default. With CSS
|
||
|
|
security protection enabled, the characters ">" (greater than) and "<"
|
||
|
|
(less than) in form input are changed to the character entities "&gt;"
|
||
|
|
and "&lt;". This is done to minimize the security risk of malicious input
|
||
|
|
which could disrupt portal content.</p>
|
||
|
|
<p>Having CSS security protection enabled can cause problems with iSeries™ Access
|
||
|
|
portlets which rely on form input to retrieve information from the user. For
|
||
|
|
example, the iSeries Dynamic
|
||
|
|
SQL portlet uses a form to retrieve a SQL statement to run. Any ">" or "<"
|
||
|
|
characters in the statement are changed to "&gt;" and "&lt;".
|
||
|
|
When the modified statement is run, it fails with this message: <tt class="msgph">[SQL0104]
|
||
|
|
Token & was not valid. Valid tokens: < > = <> <= ...</tt> </p>
|
||
|
|
<p>WebSphere Portal
|
||
|
|
provides a configuration option to disable CSS security protection. Disabling
|
||
|
|
this protection avoids the problems associated with modifying form input;
|
||
|
|
however, the security implications associated with disabling this support
|
||
|
|
need to be considered. See the Troubleshooting section of the WebSphere Portal
|
||
|
|
documentation for more information.</p>
