dokuwiki -- XSS vulnerability in spellchecker backend

Affected packages
dokuwiki < 20070626_1
dokuwiki-devel < 20070524_1


VuXML ID cddde37a-39b5-11dc-b3da-001921ab2fa4
Discovery 2007-06-26
Entry 2007-07-24

DokuWiki reports:

The spellchecker tests the UTF-8 capabilities of the used browser by sending an UTF-8 string to the backend, which will send it back unfiltered. By comparing string length the spellchecker can work around broken implementations. An attacker could construct a form to let users send JavaScript to the spellchecker backend, resulting in malicious JavaScript being executed in their browser.

Affected are all versions up to and including 2007-06-26 even when the spell checker is disabled.
