• Privilege escalation

Privilege escalation

This executable provides a mechanism for privilege escalation by indirectly enabling elevated privileges, such as setting the SUID bit or modifying the ownership of another executable.

• Comment

  This changes the root password to x, so it’s now possible to log in using, for example, su.

  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 ....

  echo -e 'x\nx' | sudo passwd
