Real-world examples include exploiting “Dirty COW,” a privilege escalation bug in the Linux kernel (upon which Android is based), to gain root access. Kernel exploitation is a potent method of privilege escalation, often requiring deep technical expertise and a thorough understanding of the kernel’s architecture.
-
Setuid/Setgid Binaries
Setuid (Set User ID) and Setgid (Set Group ID) binaries are executable files that, when run, execute with the privileges of the owner or group, respectively, rather than the user executing them. Attackers can exploit vulnerabilities in these binaries to escalate privileges. For example, if a Setuid binary has a buffer overflow vulnerability, an attacker can craft malicious input that overwrites program memory and executes code with the privileges of the binary’s owner (typically root). This technique allows attackers to gain root access by exploiting flaws in privileged programs.
-
Exploiting Misconfigurations
Misconfigurations in system settings or application permissions can create opportunities for privilege escalation. For instance, if a service is running with elevated privileges but is improperly secured, an attacker may be able to interact with it and gain access to its privileged context. Another example is the presence of world-writable files in critical system directories. These misconfigurations can be exploited by attackers to execute commands or modify system settings with elevated privileges, leading to root access.
-
Exploiting Vulnerable Apps
Vulnerable applications installed on an Android device can serve as a stepping stone for privilege escalation. If an application has a vulnerability that allows an attacker to execute arbitrary code, and that application has elevated permissions, the attacker can use that vulnerability to gain those elevated permissions. Some apps may request more permissions than they require, creating a larger attack surface. By exploiting vulnerabilities in these apps, attackers can effectively escalate their privileges to the level of the vulnerable application.
Privilege escalation is a critical phase in successfully compromising an Android device. Whether through kernel exploitation, vulnerable binaries, system misconfigurations, or vulnerable applications, the ability to elevate privileges is essential for achieving root access and gaining complete control of the system.
