yaklang/insecure-source-code-management

Gestion des fuites de code source et artefacts (.git, .svn, .hg, sauvegardes, .env). Utilisez cette compétence lors de la reconnaissance de chemins VCS, d'erreurs 403 sur des répertoires cachés, ou de fuites de sauvegardes/configurations lors de tests autorisés.

Qu'est-ce que insecure-source-code-management ?

Cette compétence permet de détecter et d'exploiter les expositions de code source et artefacts liés aux systèmes de contrôle de version (VCS) tels que .git, .svn, .hg, ainsi que les fichiers de sauvegarde et de configuration (backups, .env) lors de tests de sécurité autorisés. Elle est particulièrement utile lorsque la reconnaissance révèle des chemins VCS, des erreurs 403 sur des répertoires cachés, ou des signes de fuites de sauvegardes ou de configurations sensibles. La compétence s'appuie sur des outils comme `git-dumper`, `svn-extractor` et des techniques manuelles de dump de dépôts VCS, automatisant la récupération des données exposées pour analyser les vulnérabilités et les informations critiques (codes source, mots de passe, clés API). Elle est compatible avec les environnements d'audit de sécurité et peut être intégrée dans des workflows de pentest utilisant `yaklang` ou des scripts shell.

Que fait insecure-source-code-management ?

Gestion des fuites de code source et artefacts (.git, .svn, .hg, sauvegardes, .env). Utilisez cette compétence lorsque la reconnaissance trouve des chemins VCS, des erreurs 403 sur des répertoires cachés, ou des fuites de sauvegardes/configurations lors de tests autorisés.

Objectif

Détecter et exploiter les expositions de code source et artefacts non sécurisés sur des serveurs web ou applications cibles, dans le cadre de tests de sécurité légitimes et autorisés.

Prérequis

  • Outils : git, svn (Subversion), hg (Mercurial), curl, wget, git-dumper, svn-extractor
  • Permissions explicites de test
  • Reconnaissance préalable (scans de chemins, statuts HTTP 403, fichiers cachés)

Utilisation

Fuite .git

# Dump d'un dépôt .git exposé
git-dumper http://cible.com/.git/ ./dossier_sortie
cd dossier_sortie && git status

Fuite .svn

# Extraction de fichiers de métadonnées Subversion
svn-extractor --url http://cible.com/.svn/ --output ./sortie_svn

Fuite .hg

# Vérification manuelle
curl http://cible.com/.hg/ -L
# Téléchargement du store de données
wget -r --no-parent http://cible.com/.hg/

Sauvegardes et fichiers .env

# Recherche de sauvegardes
curl http://cible.com/backup.zip
curl http://cible.com/dump.sql
# Fichiers .env exposés
curl http://cible.com/.env

Exemples de cas

  • Scénario : Un scan trouve http://cible.com/.git/HEAD (statut 200). Utilisez git-dumper pour récupérer tout le dépôt.
  • Scénario : Erreur 403 sur http://cible.com/admin/. Tentez /admin/.git/ ou /admin/backup/.
  • Scénario : Fichier robots.txt liste Disallow: /backup/. Vérifiez /backup/ pour des sauvegardes.

Considérations légales

Utilisation uniquement avec autorisation explicite. L'exploitation non autorisée de fuites VCS est illégale. Cette compétence est conçue pour des tests de sécurité éthiques et des audits de conformité.

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

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
