Description Martin Prpič 2015-03-02 11:22:05 UTC
The following flaw was reported against tcllib:

User supplied input is directly inserted into the <textarea> as default value, e.g. a textarea named 'ta' with a parameter of ta=XXX results in `<textarea>XXX</textarea>`

This can be used to break out of the <textarea>-context and insert arbitrary HTML content such as <script>-Tags.

The attack is possible using HTTP GET requests as well as POST and multipart form encoded POST requests.
