cnsgithub created MYFACES-4279:
----------------------------------
Summary: inputText: lack of user input validation (maxlength)
Key: MYFACES-4279
URL: https://issues.apache.org/jira/browse/MYFACES-4279
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.3.2
Reporter: cnsgithub
h2. Expected Behaviour
Server side validation should be performed as well.
h2. Actual Behaviour
{{h:inputText maxlength}} is validated on client side only. However, client
side validation may be bypassed easily.
h2. Steps to reproduce
I created a small github project to reproduce this behaviour:
[https://github.com/cnsgithub/mojarra-ajax/tree/myfaces] (branch myfaces)
To reproduce:
- {{git clone [https://github.com/cnsgithub/mojarra-ajax]}}
- {{git checkout myfaces}}
- run {{mvn clean package jetty:run}}
- after the server has started, open
[http://localhost:8080/maxlength.xhtml|http://localhost:8080/index.xhtml]
- Enter some characters and press the _Submit_ button. Everything is fine.
- Press the _Hack_ button. 100 characters are written to the model.
