This encoder uses the printf(1) utility to avoid restricted characters. Some shell variable substitution may also be used if needed symbols are blacklisted. Some characters are intentionally left unescaped since it is assumed that PHP with magic_quotes_gpc enabled will escape them during request handling.

Module Ranking and Traits

Module Ranking:

  • manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.

Basic Usage
