Summary
Checks for vulnerabilities: * MS08-067, a Windows RPC vulnerability * Conficker, an infection by the Conficker worm * Unnamed regsvc DoS, a denial-of-service vulnerability I accidentally found in Windows 2000 * SMBv2 exploit (CVE-2009-3103, Microsoft Security Advisory 975497) * MS06-025, a Windows Ras RPC service vulnerability * MS07-029, a Windows Dns Server RPC service vulnerability SYNTAX: smbport: Override the default port choice. If 'smbport' is open, it's used. It's assumed to be the same protocol as port 445, not port 139. Since it probably isn't possible to change Windows' ports normally, this is mostly useful if you're bouncing through a relay or something. randomseed: Set to a value to change the filenames/service names that are randomly generated. smbbasic: Forces the authentication to use basic security, as opposed to 'extended security'. Against most modern systems, extended security should work, but there may be cases where you want to force basic. There's a chance that you'll get better results for enumerating users if you turn on basic authentication. smbsign: Controls whether or not server signatures are checked in SMB packets. By default, on Windows, server signatures aren't enabled or required. By default, this library will always sign packets if it knows how, and will check signatures if the server says to. Possible values are: - 'force': Always check server signatures, even if server says it doesn't support them (will probably fail, but is technically more secure). - 'negotiate': [default] Use signatures if server supports them. - 'ignore': Never check server signatures. Not recommended. - 'disable': Don't send signatures, at all, and don't check the server's. not recommended. More information on signatures can be found in 'smbauth.lua'. safe: If set, this script will only run checks that are known (or at least suspected) to be safe. unsafe: If set, this script will run checks that, if the system isn't patched, are basically guaranteed to crash something. Remember that non-unsafe checks aren't necessarily safe either)
