0x1D in page creates NullPointerException in RenderingManager
-------------------------------------------------------------
Key: JSPWIKI-173
URL: https://issues.apache.org/jira/browse/JSPWIKI-173
Project: JSPWiki
Issue Type: Bug
Components: Core & storage
Affects Versions: 2.4.104, 2.6.1
Environment: tested on WindowsXP with version 2.4.104 as well as on
sandbox.jspwiki.org (running 2.6?)
Reporter: Torsten Hildebrandt
Priority: Critical
Enter something containing ascii #1D in an edit-box, and press save. An
alternative way is to add this character manually into a wiki page on disc.
If the page is about to be displayed, this creates an error-message like:
JSPWiki has detected an error
Error Message
Exception
java.lang.NullPointerException
Place where detected
com.ecyrd.jspwiki.render.RenderingManager.getHTML(), line 254
...
This is makes a page containing this character undisplayable.
I consider this bug quite severe as it allows to create some form of denial of
service for all editable pages .
