Firefox 2.0.0.11 File Focus Stealing Vulnerability
Author: Dave Lewis
From Thoughts of a Technocrat:
Sorry Mozilla, but the recent file focus fix was not enough. I think Mozilla made another mistake while fixing the previous file/label issue. Because now I embed a file field and a textfield inside one label. When this happens, and you type only one time in the textfield, the focus travels to the file field and the value travels with it.
Back to the drawing board I would say. I only got it to work in Firefox, Gareth checked Safari for me, and it also works in Safari. I guess this type of exploit could function on other HTML objects as well, and could be very dangerous because it only requires a one time focus in a textfield.
Read on. Link to PoC exploit included.
