The grammar of the sudoers file is intended to be flexible enough to cover many different scenarios, such as placing restrictions on command-line parameters. For example, a user can be granted access to change anybody's password except for the root account, as follows: pete ALL = /usr/bin/passwd [A-z]*, !/usr/bin/passwd root
Mandatory Integrity Control is defined using a new access control entry (ACE) type to represent the object's IL in its security descriptor.In Windows, Access Control Lists (ACLs) are used to grant access rights (read, write, and execute permissions) and privileges to users or groups.
An application that can execute Command line or shell commands could have a Shell Injection vulnerability if it uses unvalidated input as part of an executed command. An attacker would then be able to run system commands using the application's privileges.
When an application requests higher privileges or when a user selects a "Run as administrator" option, UAC will prompt standard users to enter the credentials of an Administrator account and prompt Administrators for confirmation and, if consent is given, continue or start the process using an unrestricted token.
In computing, runas (a compound word, from “run as”) is a command in the Microsoft Windows line of operating systems that allows a user to run specific tools and programs under a different username to the one that was used to logon to a computer interactively. [1]
A privilege is applied for by either an executed program issuing a request for advanced privileges, or by running some program to apply for the additional privileges. An example of a user applying for additional privileges is provided by the sudo command to run a command as superuser ( root ) user, or by the Kerberos authentication system.
PowerShell scripts (files suffixed by .ps1) PowerShell functions; Standalone executable programs; If a command is a standalone executable program, PowerShell launches it in a separate process; if it is a cmdlet, it executes in the PowerShell process. PowerShell provides an interactive command-line interface, where the commands can be
This poses a security risk that led to the development of UAC. Users can set a process to run with elevated privileges from standard accounts by setting the process to "run as administrator" or using the runas command and authenticating the prompt with credentials (username and password) of an administrator account. Much of the benefit of ...
