Linux Privilege escalation | Gaining ROOT Access | Multiple basic to advanced techniques - cybersecurity ethicalhacking
Privilege escalation is a journey. There are no silver bullets, and much depends on the specific configuration of the target system. The kernel version, installed applications, supported programming languages, and other users’ passwords are a few key elements that will affect your road to the root shell.Privilege Escalation usually involves going from a lower permission account to a higher permission one.
Here I'll first teach you some theory about specific privilege escalation techniques & then hands-on experience on a machine. . These techniques are helpful for both Red & Blue Teams.The kernel on Linux systems manages the communication between components such as the memory , I/O, CPU on the system and applications.requires the kernel to have specific privileges; thus, a successful exploit will potentially lead to root privileges.Identify the current kernel version.
Although it sounds simple, remember that a failed kernel exploit can lead to a system crash. Make sure this potential outcome is acceptable within the scope of your penetration testing engagement before attempting a kernel exploit.First, we need to find the current kernel version of the target system so we can check if it has any vulnerabilities.Will print system information & kernel used by the system. Format -> Kernel name, Hostname, kernel release | kernel version Machine , NIS.
that can be used in the find program as an optional parameter. Here since find is running as ROOT privileges so whatever we run on it will get executed as ROOT privileges.is a curated list of Unix binaries that can be used to bypass local security restrictions in misconfigured systems. Helps in breaking out restricted shells, escalating or maintaining elevated privileges, transferring files, spawning bind and reverse shells, and facilitating the other post-exploitation tasks.
