Tor is prone to an unauthorized-access vulnerability due to a design error when handling multiple connections to the ControlPort.
|
|
|
|
An attacker can exploit this issue to reconfigure Tor and significantly weaken the anonymity provided by the software.
|
|
|
|
Tor 0.1.2.15 is confirmed vulnerable; previous versions may also be affected.
|
|
|
|
<!--
|
|
|
|
Tor < 0.1.2.16 with ControlPort enabled ( not default )
|
|
Exploit for Tor ControlPort "torrc" Rewrite Vulnerability
|
|
http://secunia.com/advisories/26301
|
|
|
|
Rewrites the torrc to log to a different location: C:\Documents and
|
|
Settings\All Users\Start Menu\Programs\Startup\t.bat
|
|
Also enables debug logging, and an erroneous ExitPolicy looking
|
|
something like this: reject*:1337\'&' calc.exe this will output:
|
|
[debug] parse_addr_policy(): Adding new entry 'reject*:1337'& calc.exe
|
|
to the debug log -> t.bat which will run calc.exe on next boot.
|
|
|
|
This is not very silent though, t.bat will contain something like 45
|
|
rows of crap which the user will see in about 1 sec, drop me a mail if
|
|
you have a better way.
|
|
|
|
Either have a TOR user visit this HTML or inject it into her traffic
|
|
when you're a TOR exit.
|
|
If you inject, just replace </HEAD> with everything in <HEAD> + </HEAD>
|
|
( that's why I tried to fit everything inside <HEAD />), and fix
|
