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
