VULNERABILITY DETAILS
|
|
The latest version of Google Chrome (Tested on Version 24.0.1312.57)
|
|
fails to properly recognize HTTP Basic Authentication when injected in
|
|
various HTML tags. As a result of this behavior Chrome will not alert
|
|
the user when HTTP Basic Authentication is taking place or when
|
|
credentials are rejected. This behavior is particularly concerning
|
|
with respect to small office and home routers. Such devices are easily
|
|
brute forced using this method. Many of these devices have the default
|
|
password enabled which brings me to part II of this bug. Silent HTTP
|
|
Authentication allows the attacker to log into the router and change
|
|
settings with no alerts and or warnings issued by Chrome. The end
|
|
result allows an attacker to brute force the router login, connect to
|
|
the router, enable remote administration and of course control all
|
|
information on the entire network via DNS attacks etc.
|
|
REPRODUCTION CASE
|
|
I have attached the following files:
|
|
|
|
sploit.txt - Indicates the buggy code.
|
|
jquery.js - Used for real world scenario but not needed for bug.
|
|
brute.js - Real world attack scenario for this bug.
|
|
index.html - HTML Attack Page
|
|
attack.php - Payload file for Linksys Routers.

IMPACT
|
|
The impact for this bug is enormous. Tens of millions of home routers
|
|
can easily be completely compromised. Distributed brute force attacks
|
|
can be performed on any HTTP Authentication portal.

|
|
|
RECOMMENDATIONS
|
|
Reference how Firefox and Safari handle the attached code.
