Shell

This executable can spawn an interactive system shell.
  1. This function can be performed by any unprivileged user.
    nano
    ^R^X
    reset; sh 1>&0 2>&0
    This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.
    RemarksIf there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....
    nano
    ^R^X
    reset; sh 1>&0 2>&0
    This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.
    RemarksThis executable runs commands using the system shell, e.g., via functions like system, so it only works for distributions where the shell does not drop SUID privileges.
    nano
    ^R^X
    reset; sh 1>&0 2>&0
  2. CommentThe SPELL environment variable can be used in place of the -s option if the command line cannot be changed.
    This function can be performed by any unprivileged user.
    nano -s /bin/sh
    /bin/sh
    ^T^T
    This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.
    RemarksIf there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....
    nano -s /bin/sh
    /bin/sh
    ^T^T
    This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.
    RemarksThis executable runs commands directly, e.g., via functions like exec, remember to omit the -p argument of every /bin/sh invocation for distributions where the default shell does not drop SUID privileges.
    nano -s '/bin/sh -p'
    /bin/sh -p
    ^T^T

File write

This executable can write data to local files.
  1. This function can be performed by any unprivileged user.
    nano /path/to/output-file
    DATA
    ^O
    This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.
    RemarksIf there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....
    nano /path/to/output-file
    DATA
    ^O
    This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.
    nano /path/to/output-file
    DATA
    ^O

File read

This executable can read data from local files.
  1. CommentThe file content is displayed in the terminal interface.
    This function can be performed by any unprivileged user.
    nano /path/to/input-file
    This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.
    RemarksIf there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....
    nano /path/to/input-file
    This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.
    nano /path/to/input-file
    RemarksThe content is corrupted or otherwise altered by the process, thus it might not be suitable for handling arbitrary binary data.
