shell:
label: Shell
description: It can be used to break out from restricted environments by spawning an interactive system shell.
command:
label: Command
description: It can be used to break out from restricted environments by running non-interactive system commands.
reverse-shell:
label: Reverse shell
description: It can send back a reverse shell to a listening attacker to open a remote network access.
non-interactive-reverse-shell:
label: Non-interactive reverse shell
description: It can send back a non-interactive reverse shell to a listening attacker to open a remote network access.
bind-shell:
label: Bind shell
description: It can bind a shell to a local port to allow remote network access.
non-interactive-bind-shell:
label: Non-interactive bind shell
description: It can bind a non-interactive shell to a local port to allow remote network access.
file-upload:
label: File upload
description: It can exfiltrate files on the network.
file-download:
label: File download
description: It can download remote files.
file-write:
label: File write
description: It writes data to files, it may be used to do privileged writes or write files outside a restricted file system.
file-read:
label: File read
description: It reads data from files, it may be used to do privileged reads or disclose files outside a restricted file system.
library-load:
label: Library load
description: It loads shared libraries that may be used to run code in the binary execution context.
suid:
label: SUID
description: |
If the binary has the SUID bit set, it does not drop the elevated privileges and may be exploited to access the file system, escalate or maintain privileged access as a SUID backdoor. If it is used to run `sh -p`, omit the `-p` argument on systems like Debian (<= Stretch) that allow the default `sh` shell to run with SUID privileges.
This example creates a local SUID copy of the binary and runs it to maintain elevated privileges. To exploit an existing SUID binary skip the first command and run the program using its original path.
sudo:
label: Sudo
description: If the binary is allowed to run as superuser by `sudo`, it does not drop the elevated privileges and may be used to access the file system, escalate or maintain privileged access.
capabilities:
label: Capabilities
description: If the binary has the Linux `CAP_SETUID` capability set or it is executed by another binary with the capability set, it can be used as a backdoor to maintain privileged access by manipulating its own process UID.
limited-suid:
label: Limited SUID
description: |
If the binary has the SUID bit set, it may be exploited to access the file system, escalate or maintain access with elevated privileges working as a SUID backdoor. If it is used to run commands (e.g., via `system()`-like invocations) it only works on systems like Debian (<= Stretch) that allow the default `sh` shell to run with SUID privileges.
This example creates a local SUID copy of the binary and runs it to maintain elevated privileges. To exploit an existing SUID binary skip the first command and run the program using its original path.
