yaklang/unauthorized-access-common-services

일반적으로 노출된 서비스에 대한 무단 접속 플레이북입니다. Redis, Rsync, PHP-FPM, AJP/Ghostcat, Hadoop YARN, H2 콘솔 등과 같은 관리 인터페이스가 인증 없이 노출된 경우 사용하세요.

unauthorized-access-common-services란 무엇인가요?

이 스킬은 인증 없이 노출된 일반적인 서비스(Redis, Rsync, PHP-FPM, AJP/Ghostcat, Hadoop YARN, H2 콘솔 등)에 대한 무단 접속을 탐지하고 악용하는 방법을 제공합니다. 보안 엔지니어나 침투 테스터가 취약한 서비스를 식별하고, 실제 공격 시나리오에서 무단 접근 위험을 평가하는 데 유용합니다. 이 스킬은 Yaklang 플랫폼에서 사용되며, 자동화된 스크립트와 함께 다양한 서비스의 기본 인증 우회, 취약점 스캐닝, 그리고 PoC(Proof of Concept) 실행을 포함합니다. 주로 Redis의 기본 인증 미비, Hadoop YARN의 REST API 취약점, H2 콘솔의 인증 우회 등 OWASP Top 10에 해당하는 취약점에 대응합니다.

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

yaklang/401-403-bypass-techniques

401/403 bypass playbook. Use when encountering access-denied responses on admin panels, API endpoints, or restricted paths. Covers path manipulation, HTTP method tampering, header injection, protocol downgrade, and automated bypass tools.

yaklang/active-directory-acl-abuse

Active Directory ACL abuse playbook. Use when exploiting misconfigured AD permissions including GenericAll, WriteDACL, DCSync rights, shadow credentials, LAPS reading, GPO abuse, and BloodHound-guided attack paths.

yaklang/active-directory-certificate-services

AD Certificate Services attack playbook. Use when targeting misconfigured AD CS for privilege escalation via ESC1-ESC13 template abuse, NTLM relay to enrollment, CA officer abuse, and certificate-based persistence.

yaklang/active-directory-kerberos-attacks

Kerberos attack playbook for Active Directory. Use when targeting AD authentication via AS-REP roasting, Kerberoasting, golden/silver/diamond tickets, delegation abuse, or pass-the-ticket attacks.

yaklang/ai-ml-security

AI/ML security playbook. Use when assessing model supply chain attacks (pickle RCE, poisoned weights), adversarial examples, model poisoning, model stealing, data privacy attacks (membership inference, model inversion), and autonomous agent security risks.

yaklang/android-pentesting-tricks

Android pentesting playbook. Use when testing Android applications for SSL pinning bypass, exported component abuse, WebView vulnerabilities, intent redirection, root detection bypass, tapjacking, and backup extraction during authorized mobile security assessments.

yaklang/anti-debugging-techniques

Anti-debugging detection and bypass playbook. Use when reversing protected binaries that detect debuggers via ptrace, PEB flags, timing checks, or signal/exception handlers on Linux and Windows.

yaklang/api-auth-and-jwt-abuse

API authentication and JWT abuse playbook. Use when testing bearer tokens, API keys, claim trust, header spoofing, rate limits, and API auth boundary weaknesses.

yaklang/api-authorization-and-bola

API authorization and BOLA testing playbook. Use when APIs expose object identifiers, nested resources, hidden writable fields, or weak function-level authorization.

yaklang/api-recon-and-docs

API reconnaissance and documentation review playbook. Use when discovering endpoints, schemas, versions, OpenAPI specs, hidden docs, and surface area for API testing.

yaklang/api-sec

Entry P1 category router for API security. Use when choosing between API recon, authorization, token abuse, and hidden-parameter workflows before any deeper API topic skill.

yaklang/arbitrary-write-to-rce

Arbitrary write to RCE playbook. Use when you have an arbitrary write primitive (from heap exploitation, format string, or OOB write) and need to convert it into code execution by targeting GOT, hooks, _IO_FILE vtable, exit_funcs, TLS_dtor_list, modprobe_path, .fini_array, or C++ vtables.

yaklang/authbypass-authentication-flaws

Authentication bypass testing playbook. Use when assessing login flows, password reset logic, account recovery, MFA bypass, token predictability, brute-force resistance, and session boundary flaws.

yaklang/auth-sec

Entry P1 category router for authentication and authorization. Use when testing login flows, sessions, object authorization, JWT, OAuth, CORS, CSRF, and enterprise SSO weaknesses before any deeper auth topic skill.

yaklang/binary-protection-bypass

Binary protection bypass playbook. Use when identifying and bypassing ASLR, PIE, NX/DEP, stack canary, RELRO, FORTIFY_SOURCE, CET, and MTE protections in ELF binaries to enable exploitation.

yaklang/browser-exploitation-v8

Browser and V8 exploitation playbook. Use when exploiting JavaScript engine vulnerabilities including JIT type confusion, incorrect bounds elimination, and V8 sandbox bypass to achieve renderer RCE and sandbox escape in Chrome/Chromium.

yaklang/business-logic-vuln

Entry P1 category router for business logic testing. Use when workflow abuse, race conditions, pricing flaws, or multi-step state attacks matter more than parser-level input injection.

yaklang/business-logic-vulnerabilities

Business logic vulnerability playbook. Use when reasoning about workflows, race conditions, price manipulation, coupon abuse, state machines, and multi-step authorization gaps.

yaklang/classical-cipher-analysis

Classical cipher analysis playbook. Use when encountering substitution ciphers, Vigenere, transposition, XOR, or encoded text in CTF challenges that requires frequency analysis, Kasiski examination, or known-plaintext cryptanalysis.

yaklang/clickjacking

Clickjacking playbook. Use when testing whether target pages can be framed, whether X-Frame-Options or CSP frame-ancestors are properly configured, and whether UI redress attacks can trigger sensitive actions.
