How does http: // a / %% 30% 30 work?

Question

Yep, the link http://anything/%%30%30 causes my Google Chrome browser to crash even when I hover over it.

How it works?

Answer 1

Tom Scott explains this beautifully in his video: Link that could cause Chrome to crash: http: // a / %% 30% 30

Steps:

• http://a/%%30%30 becomes http://a/%00 because %30 is 0
• http://a/%00 becomes http://a/<NULL> because %00 is a NULL character

(see table ASCII )

The bug of Andris Atteki was fixed , which simply added a null character to the string.

Answer 2

Expect this to no longer work (from 45).

Answer 3
