A proof-of-concept exploit for CVE-2021-4034 (PwnKit), a local privilege escalation vulnerability in polkit's pkexec utility. It is a small C program that, when compiled and run on a vulnerable Linux system, escalates the local user to root.

Use cases

• test if a Linux system is vulnerable to PwnKit CVE-2021-4034
• demonstrate local privilege escalation via pkexec
• verify polkit patching on Debian or CentOS hosts
• reproduce the PwnKit vulnerability in a lab environment
• check pkexec privilege escalation during a security assessment

When to choose

• you need a simple, verified PoC to test pkexec privilege escalation on Debian 10 or CentOS 7
• you are validating whether systems are patched against CVE-2021-4034
• you want a minimal C exploit to study the PwnKit vulnerability

When to avoid

• you need a comprehensive vulnerability scanner rather than a single-CVE PoC
• your systems are already patched against CVE-2021-4034
• you require a maintained tool with a license and ongoing updates
