Name: TFTP Fetch, Linux Command Shell, Bind TCP Stager Module: payload/cmd/linux/tftp/x86/shell/bind_nonx_tcp Platform: Linux Arch: cmd Needs Admin: No Total size: 114 Rank: Normal Provided by: Brendan Watters Spencer McIntyre skape Basic options: Name Current Setting Required Description ---- --------------- -------- ----------- FETCH_COMMAND CURL yes Command to fetch payload (Accepted: CURL, FTP, TFTP, TNFTP, WGET) FETCH_DELETE false yes Attempt to delete the binary after execution FETCH_FILELESS none yes Attempt to run payload without touching disk by using anonymous handles, requires Linux ≥3.17 (for Python variant also Python ≥3.8 (Accepted: none, bash, python3.8+) FETCH_SRVHOST yes Local IP to use for serving payload FETCH_SRVONCE true yes Stop serving the payload after it is retrieved FETCH_SRVPORT 8080 yes Local port to use for serving payload FETCH_URIPATH no Local URI to use for serving payload LPORT 4444 yes The listen port RHOST no The target address When FETCH_COMMAND is one of CURL,WGET: Name Current Setting Required Description ---- --------------- -------- ----------- FETCH_PIPE false yes Host both the binary payload and the command so it can be piped directly to the shell. When FETCH_FILELESS is none: Name Current Setting Required Description ---- --------------- -------- ----------- FETCH_FILENAME WlPZFdeTUcLW no Name to use on remote system when storing payload; cannot contain spaces or slashes FETCH_WRITABLE_DIR ./ yes Remote writable dir to store payload; cannot contain spaces Description: Fetch and execute a x86 payload from a TFTP server. Spawn a command shell (staged). Listen for a connection Name Current Setting Required Description ---- --------------- -------- ----------- AppendExit false no Prepend a stub that will break out of a chroot (includes setreuid to root) AutoRunScript no A script to run automatically on session creation. AutoVerifySession true yes Automatically verify and drop invalid sessions CommandShellCleanupCommand no A command to run before the session is closed EXE::Custom no Use custom exe instead of automatically generating a payload exe EXE::EICAR false no Generate an EICAR file instead of regular payload exe EXE::FallBack false no Use the default template in case the specified one is missing EXE::Inject false no Set to preserve the original EXE function EXE::OldMethod false no Set to use the substitution EXE generation method. EXE::Path no The directory in which to look for the executable template EXE::Template no The executable template file name. EnableStageEncoding false no Encode the second stage payload FetchHandlerDisable false yes Disable fetch handler FetchListenerBindAddress no The specific IP address to bind to to serve the payload if different from FETCH_SRVHOST FetchListenerBindPort no The port to bind to if different from FETCH_SRVPORT InitialAutoRunScript no An initial script to run on session creation (before AutoRunScript) MSI::Custom no Use custom msi instead of automatically generating a payload msi MSI::EICAR false no Generate an EICAR file instead of regular payload msi MSI::Path no The directory in which to look for the msi template MSI::Template no The msi template file name MSI::UAC false no Create an MSI with a UAC prompt (elevation to SYSTEM if accepted) PayloadUUIDName no A human-friendly name to reference this unique payload (requires tracking) PayloadUUIDRaw no A hex string representing the raw 8-byte PUID value for the UUID PayloadUUIDSeed no A string to use when generating the payload UUID (deterministic) PayloadUUIDTracking false yes Whether or not to automatically register generated UUIDs PingbackRetries 0 yes How many additional successful pingbacks PingbackSleep 30 yes Time (in seconds) to sleep between pingbacks PrependChrootBreak false no Prepend a stub that will break out of a chroot (includes setreuid to root) PrependFork false no Prepend a stub that starts the payload in its own process via fork PrependSetgid false no Prepend a stub that executes the setgid(0) system call PrependSetregid false no Prepend a stub that executes the setregid(0, 0) system call PrependSetresgid false no Prepend a stub that executes the setresgid(0, 0, 0) system call PrependSetresuid false no Prepend a stub that executes the setresuid(0, 0, 0) system call PrependSetreuid false no Prepend a stub that executes the setreuid(0, 0) system call PrependSetuid false no Prepend a stub that executes the setuid(0) system call StageEncoder no Encoder to use if EnableStageEncoding is set StageEncoderSaveRegisters no Additional registers to preserve in the staged payload if EnableStageEncoding is set StageEncodingFallback true no Fallback to no encoding if the selected StageEncoder is not compatible VERBOSE false no Enable detailed status messages WORKSPACE no Specify the workspace for this module
