Mozilla Navigator Object
The following bug (mfsa2006-45) was tested on Firefox 1.5.0.4 running on
Windows 2000 SP4, Windows XP SP2, and a recently updated Gentoo Linux
system. This bug was reported by TippingPoint and fixed in the latest
1.5.0.5 release of Mozilla Firefox. This is different from the bug I
reported (mfsa2006-48) and is trivial to turn into a working exploit.
The demonstration link below will attempt to launch "calc.exe" on
Windows systems, execute "touch /tmp/METASPLOIT" on Linux systems, and
bind a command shell to port 4444 for Mac OS X Intel and PowerPC systems
(thanks Todd and nemo!).
window.navigator = (0x01020304 / 2);
java.lang.reflect.Runtime.newInstance(
java.lang.Class.forName("java.lang.Runtime"), 0);
