Privilege Escalation

Privilege escalation is a cybersecurity concept where an attacker gains elevated access to resources that are normally protected from an application or user. It involves exploiting vulnerabilities, misconfigurations, or design flaws to move from a lower-privilege account (e.g., a standard user) to a higher-privilege one (e.g., an administrator or root). This technique is critical in penetration testing and security assessments to identify and mitigate risks in systems.

Also known as: PrivEsc, Privilege Elevation, Escalation of Privileges, EoP, Privilege Abuse

Why learn Privilege Escalation?

Developers should learn privilege escalation to build more secure applications by understanding common attack vectors, such as insecure permissions, buffer overflows, or weak authentication. It is essential for roles in cybersecurity, penetration testing, and secure software development to prevent unauthorized access and protect sensitive data. Use cases include security audits, red team exercises, and compliance testing in industries like finance, healthcare, and government.
