Need help on rich:fileUpload issue on Linux

Question

I'm using rich:fileUpload in my application on linux when I try to upload any file containing html code in file name ie "file<img src=xyz onerror=alert('TEST')>Name.png" , it gives me javascript alert before uploading the file. I tried it on live demo and found the same issue there as well. How can I restrict/escape execution of html/script or XSS in file name on linux?

You can try it yourself by following steps on linux.

Create a file with name "file<img src=xyz onerror=alert('TEST')>Name.png" Access rich:fileUpload demo on richfaces showcase using below url. Upload file and you will see a javascript alert.

Answer 1

I try to upload any file containing html code in file name ie "fileName.png".

You are saying html code in file name, but I don't see any html in "fileName.png".

If I'm not wrong file name should be something like file<img src=x onerror=alert('Javascript')>.pdf .
