## What it is
A proof-of-concept exploit for CVE-2021-3156 (Baron Samedit), a heap-based buffer overflow in sudo. It is a C command-line tool that escalates privileges to root on vulnerable Linux systems, with support for multiple targets and experimental brute-force target finding.

## Use cases
- test if my sudo is vulnerable to CVE-2021-3156
- demonstrate the Baron Samedit sudo heap overflow exploit
- escalate to root on a vulnerable Linux box for a pentest report
- study how a heap-based overflow in sudo is exploited
- brute-force exploit parameters for different sudo targets

## When to choose
- you need to verify or demonstrate CVE-2021-3156 on a known-vulnerable Linux system
- you are doing authorized penetration testing or security research on sudo
- you want a working reference exploit to study heap overflow techniques

## When to avoid
- you need a general vulnerability scanner rather than a single-CVE exploit
- your systems are patched or run non-Linux platforms
- you lack explicit authorization to test the target system

## Facets
- artifact type: cli-tool
