Java 0-Day Vulnerability Exploit Demo (CVE-2012-4681)
This is a demo of the Java 0-Day Vulnerability made public on 08-26-2012 (now CVE-2012-4681): http://youtu.be/HO4yO7_5sEc?hd=1 (watch in HD)
This vulnerability was found being exploited in the wild and discovered by Michael Schierl.
This exploit was written based on the PoC published by @jduck1337 at http://pastie.org/pastes/4594319/text
Tested on Windows 7 with Internet Explorer, Firefox and Chrome (keep in mind this affects Java on all platforms)
The exploit is extremely easy to implement, not much needs to be changed from the public PoC besides adding code to drop a payload.

Exploiting MySQL Authentication Bypass Vulnerability (CVE-2012-2122)
Exploitation of this critical vulnerability is trivial and requires only to perform several authentication attempts with any password and a valid username until the MySQL server grants access.
After successful exploitation this exploit dumps information from the target MySQL server such as: version, available databases, password hashes of MySQL users to be cracked later, dumps some system files, in this example, /etc/password, etc. Depending on the configuration of the target MySQL server and privileges of the user selected other actions can be performed.

The cleartext passwords dumped include passwords used to login to the Windows box interactively.
What is WCE?
Windows Credentials Editor (WCE) v1.3beta allows you to
NTLM authentication:
* List logon sessions and add, change, list and delete associated credentials (e.g.: LM/NT hashes)
* Perform pass-the-hash on Windows natively
* Obtain NT/LM hashes from memory (from interactive logons, services, remote desktop connections, etc.) which can be
used to authenticate to other systems. WCE can perform this task without injecting code, just by reading and decrypting information stored in Windows internal memory structures. It also has the capability to automatically switch to code injection when the aforementioned method cannot be performed
Kerberos authentication:
* Dump Kerberos tickets (including the TGT) stored in Windows machines
* Reuse/Load those tickets on another Windows machines, to authenticate to other systems and services
* Reuse/Load those tickets on *Unix machines, to authenticate to other systems and services
Digest Authentication:
* Obtain cleartext passwords entered by the user when logging into a Windows system, and stored by the Windows Digest Authentication security package
Supported Platforms
Windows Credentials Editor supports Windows XP, 2003, Vista, 7 and 2008.
