By using the sudo command in Linux systems, regular users can elevate their privileges to execute commands that require root permissions.
By using the su command, you can switch to the root user and then perform the necessary operations.
Edit the sudoers file using visudo: By editing the sudoers file, you can add a user to the sudo group, allowing them to use the sudo command to elevate their privileges.
By using setuid permissions, you can set a certain executable file to have setuid permissions, allowing the program to have the file owner’s permissions when running, thus elevating its privileges.
Using privilege escalation vulnerabilities: Sometimes there are privilege escalation vulnerabilities in a system, which attackers can exploit to elevate their privileges.
Utilize Linux privilege escalation tools such as sudo, su, and pkexec to help users elevate their permissions.
