Original Entry Date: Jul 31 2008
|
Impact: Modification of system information, User access via network
|
Exploit Included: Yes
|
Description: A vulnerability was reported in Sun Java. A remote user with the ability to masquerade as the update server can install arbitrary code on the target user's system.
The update software does not digitally sign and verify software updates. A remote user with the ability to masquerade as the update
server can cause arbitrary code to be installed on the target user's system when the target user's Java update utility performs
an update.
A remote user can conduct DNS spoofing attacks, man-in-the-middle attacks, or other methods to potentially masquerade
as the update server.

ISR-evilgrade: is a modular framework that allow us to take advantage of poor upgrade implementations
by injecting fake updates.
* How does it work?
It works with modules, each module implements the structure needed to emulate a false update of speci
fic applications/systems.
Evilgrade needs the manipulation of the victim dns traffic.
Attack vectors:
---------------------
Internal scenary: (Internal DNS access,ARP spoofing,DNS Cache Poisoning, DHCP spoofing)
External scenary: (Internal DNS access,DNS Cache Poisoning)
* What are the supported OS?
The framework is multiplaform, it only depends of having the right payload for the target platform to
be exploited.
Implemented modules:
---------------------------------
- Java plugin
- Winzip
- Winamp
- MacOS
- OpenOffices
- iTunes
- Linkedin Toolbar
- DAP [Download Accelerator]
- notepad++
- speedbit
..:: DEMO
Demo feature - (Java plugin + Dan Kaminsky´s Dns vulnerability) = remote pwned.
