Windows uses access tokens to determine the ownership of a running process. This API does not validate that the program requesting root privileges comes from a reputable source or has been maliciously modified.Īdversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls. The purpose of this API is to give application developers an easy way to perform operations with root privileges, such as for application installation or updating. Adversaries may do this to execute commands as other users or spawn processes with higher privileges.Īdversaries may leverage the AuthorizationExecuteWithPrivileges API to escalate privileges by prompting the user for credentials.

The impact to the user ranges from denying the operation under high enforcement to allowing the user to perform the action if they are in the local administrators group and click through the prompt or allowing them to enter an administrator password to complete the action.Īdversaries may perform sudo caching and/or use the suoders file to elevate privileges. Windows User Account Control (UAC) allows a program to elevate its privileges (tracked as integrity levels ranging from low to high) to perform a task under administrator-level permissions, possibly by prompting the user for confirmation. However, there are instances where programs need to be executed in an elevated context to function properly, but the user running them doesn’t need the elevated privileges.Īdversaries may bypass UAC mechanisms to elevate process privileges on system. Normally an application is run in the current user’s context, regardless of which user or group owns the application. On Linux or macOS, when the setuid or setgid bits are set for an application, the application will run with the privileges of the owning user or group respectively.

An adversary can perform several methods to take advantage of built-in control mechanisms in order to escalate privileges on a system.Īn adversary may perform shell escapes or exploit vulnerabilities in an application with the setsuid or setgid bits to get code running in a different user’s context. Authorization has to be granted to specific users in order to perform tasks that can be considered of higher risk. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine. Adversaries may circumvent mechanisms designed to control elevate privileges to gain higher-level permissions.
