Open Source Programs
Season of Bugs

Season of Bugs (SOB)

Security research meets open source. Find vulnerabilities, get recognized.

Program Overview

Season of Bugs focuses on security testing, vulnerability discovery, and security improvements in open source projects.

Required Skills

Technical Foundation

  1. Programming Languages

    • C/C++ for low-level vulnerabilities
    • Python for security tooling
    • JavaScript for web security
    • Assembly for exploit development
  2. Security Knowledge

    • Common vulnerability types (OWASP Top 10)
    • Exploitation techniques
    • Secure coding practices
    • Cryptography basics
  3. Tools

    • Static analyzers (Coverity, SonarQube)
    • Dynamic testing (Valgrind, AddressSanitizer)
    • Fuzzers (AFL, libFuzzer)
    • Network tools (Wireshark, Burp Suite)

Vulnerability Classification

SeverityBounty RangeExample
Critical2,0002,000-5,000+Remote code execution, auth bypass
High1,0001,000-2,000SQL injection, XSS with major impact
Medium500500-1,000CSRF, info disclosure
Low100100-500Minor info leak, config issues

Reporting Process

Discover Vulnerability

  • Use fuzzing, code review, or dynamic testing
  • Confirm reproducibility
  • Assess impact and scope

Write Detailed Report

  • Clear description of vulnerability
  • Step-by-step reproduction
  • Proof-of-concept code/exploit
  • Suggested fix

Responsible Disclosure

  • Report privately to security team
  • Give time to patch (90 days standard)
  • Don't publicize until fix is released

Follow Up

  • Answer questions from maintainers
  • Test proposed patches
  • Help with CVE assignment

Sample Vulnerability Report Template

## Summary
Brief one-line description of the vulnerability
 
## Severity
[Critical/High/Medium/Low] + CVSS score if calculated
 
## Affected Components
- Package: [name and version]
- File: [filename]
- Function: [function name]
- Line: [line number]
 
## Vulnerability Details
Detailed technical explanation of the issue
 
## Reproduction Steps
1. Step one
2. Step two
3. Expected: [what should happen]
4. Actual: [what actually happens]
 
## Proof of Concept
```code
[PoC exploit code]

Impact Assessment

  • Who is affected
  • What can attacker achieve
  • Likelihood of exploitation

Suggested Fix

Ethics & Legal

⚠️

Critical: Legal Boundaries

Always:

  • Get written permission before testing
  • Test only in scope systems
  • Follow responsible disclosure
  • Don't access/modify production data

Never:

  • Test production systems without permission
  • Publicize vulnerabilities before patches
  • Use found vulnerabilities maliciously
  • Share exploits publicly before fixes
