Skill: Verifying a New Challenge

This skill provides a comprehensive workflow and checklist for verifying that a newly added challenge fulfills all necessary preconditions, metadata requirements, and project conventions in OWASP Juice Shop.

General Workflow

1. Analyze the Challenge Definition: Review the new entry in data/static/challenges.yml.
2. Verify Configuration: Check if the challenge is correctly represented in lib/config.schema.ts and config/fbctf.yml.
3. Check Translations: Ensure labels and descriptions for any new categories or tags are present in frontend/src/assets/i18n/en.json.
4. Review Supporting Assets:
   • Verify Hacking Instructor scripts (if applicable).
   • Verify Coding Challenge files (if applicable).
5. Audit Tests: Ensure tests properly handle disabledEnv constraints.
6. Report Findings: Summarize any missing or incorrect metadata, broken setups, or inconsistencies.

1. Challenges YAML (data/static/challenges.yml)

Each entry in challenges.yml must adhere to the following rules:

• Uniqueness: Both name and key must be unique across all challenges.
• Key Format: The key should be camelCase and typically end with Challenge (e.g., loginAdminChallenge).
• Category: Must be an existing category (see en.json) or a new one.
  • Existing categories: Broken Access Control, Broken Anti Automation, Broken Authentication, Cryptographic Issues, Improper Input Validation, Injection, Insecure Deserialization, Miscellaneous, Security Misconfiguration, Security through Obscurity, Sensitive Data Exposure, Unvalidated RedirectS, Vulnerable Components, XSS, XXE, Observability Failures.
• Difficulty: An integer between 1 and 6.
• Description:
  • Can contain basic HTML (e.g., <i>, <code>, <a>).
  • Must be clear and concise, consistent with existing challenge descriptions.
  • Avoid duplicates (similar description/category to other challenges).
• Hints:
  • Maximum: 6-7 hints.
  • Average: 3-5 hints are preferred.
  • Content: Should gradually lead the user to the solution without revealing it.
• Mitigation URL:
  • If present it must be an OWASP resource.
  • OWASP Cheat Sheet is strongly preferred if a relevant one exists for the challenge's scope.
• Tags:
  • Optional. Existing tags: Danger Zone, Good for Demos, Prerequisite, OSINT, Contraption, Shenanigans, Tutorial, Brute Force, Good Practice, Code Analysis, Web3, With Coding Challenge, AI / LLM.
• Disabled Environments (disabledEnv):
  • Values: Docker, Heroku, Windows.
  • Used for challenges that are technically incompatible or too dangerous for certain environments (e.g., RCE).

---

2. Configuration (lib/config.schema.ts & config/fbctf.yml)

The challenge must be integrated into the CTF mode configuration:

lib/config.schema.ts

• The challenge key must be added to the CHALLENGE_KEYS array in models/challenge.ts (which is the source of truth for the ctf.countryMapping record keys).

config/fbctf.yml

• An entry for the challenge key must be added under ctf.countryMapping.
• Each entry needs a name (Country) and a code (ISO 3166-1 alpha-2 or similar).
• Uniqueness: Both the country name and code must be unique in this file to avoid conflicts in CTF frameworks.

---

3. Translations (frontend/src/assets/i18n/en.json)

If the challenge introduces a new category or a new tag:

• Category: Add CATEGORY_<UPPER_CASE_NAME> and CATEGORY_<UPPER_CASE_NAME>_DESCRIPTION.
• Tag: Add TAG_<UPPER_CASE_NAME> and TAG_<UPPER_CASE_NAME>_DESCRIPTION.
• Replace spaces with underscores in the <UPPER_CASE_NAME> (e.g., Good for Demos -> GOOD_FOR_DEMOS).

---

4. Hacking Instructor Scripts

If tutorial is specified in challenges.yml:

• A script must exist in frontend/src/hacking-instructor/challenges/.
• The script filename should match the challenge key (sometimes without the Challenge suffix).
• Rules:
  • Follow Tutorials Guide.
  • Use highlight and text steps effectively.
  • Must be consistent in tone and complexity with existing scripts.

---

5. Coding Challenges

If the challenge has an associated coding challenge:

• Files must be present in data/static/codefixes/.
• Required Files:
  • <challengeKey>.info.yml: Contains fixes (explanations) and hints.
  • <challengeKey>_1_correct.ts: The fixed version of the code snippet.
  • <challengeKey>_2.ts, <challengeKey>_3.ts, etc.: Vulnerable variations.
• Rules:
  • Follow Code Snippets Guide.
  • Explanations for both correct and incorrect fixes must be clear.

---

6. Testing Requirements

• If the challenge has disabledEnv set, the corresponding API or Cypress tests must be wrapped in an enablement check:

  if (utils.isChallengeEnabled(challenges.myNewChallenge)) {
    it('should solve my new challenge...', () => {
      // test logic
    })
  }
  

• Import utils from ../../lib/utils and challenges from ../../data/datacache (or similar depending on the test type).

---

Inferred Rules & Best Practices

• Consistency: Challenge names should be evocative but not overly long. Description and hints should follow the established style (sentence case, punctuation).
• HTML Sanitization: Ensure HTML tags in descriptions are properly closed.
• Duplicate Detection: Before adding a challenge, search existing ones for similar names, categories, or descriptions to ensure it adds unique value.
• Difficulty Calibration:
  • 1: Trivial (no tools needed).
  • 2-3: Intermediate (basic tools like DevTools or Burp/ZAP needed).
  • 4-5: Advanced (sophisticated bypasses, scripting, or deep research).
  • 6: Expert (multi-step, obscure vulnerabilities, or high technical hurdle).
