Realvnc bypass auth connection failure

Hi Mr Moore. I tested the same exploit from Metasploit in Backtrack (running as a virtual machine) against my vulnerable RealVNC server (also a virtual machine) and was successful in gaining remote access without requiring the VNC password. I attribute my previous failure to the fact that the exploit could not locate my VNC client (within XP) versus the fact that it automatically found and launched the TightVNC client in Backtrack. Thanks for your time and feedback. On 7/31/06, Mervyn Heng <barcajax at gmail.com> wrote:
Mr Moore, you are right about port 5900. It was not listening on my machine. I can't put my finger on why its not listening though. Any pointers?

Then try connecting to this as localhost/127.0.0.1, either with the GUI or using the vncviewer command line (vncviewer 127.0.0.1::5900). If this fails, try connecting manually with telnet or netcat. I can't reproduce that issue on the Metasploit test machines. -HD On Sunday 30 July 2006 20:07, Mervyn Heng wrote:Tried doing the same using the exploit provided by Metasploit but with no luck. Metasploit states that it is listening for VNC connections on 0.0.0.0:5900 but when I used the VNC viewer by specifying localhost, 127.0.0.1, 0.0.0.0 or the host OS IP, I keep getting a connection error message. Already turned off the firewall on the virtual machine and host OS... any ideas why I can't connect to the VNC server throughMetasploit as a proxy?
