database-security

An authorized security review of databases and their surrounding configuration. It covers PostgreSQL, MySQL, Microsoft SQL Server, MongoDB, and Redis, including exposure, accounts, permissions, and dangerous features.

In plain words
What is it for?
Use it to review network binding and TLS, authentication, roles, sensitive-table access, risky database features, audit logs, backups, and safe validation of injection or command paths.
Why use it?
It helps reveal databases that are reachable when they should not be, accounts with excessive access, weak settings, and paths from application access to higher privileges. Destructive production actions are excluded unless explicitly allowed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

database-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Database Security Assessment

ACTION REQUIRED (Execute immediately after reading)

  1. NOW: Read precedent-pentest; destructive statements on production databases are prohibited unless explicitly permitted
  2. NOW: The scope must clearly state instances, account permissions, and whether write/delete is allowed
  3. NEXT: Client tool paths
  4. ACT: Exposure surface → Authentication → Authorization → Configuration → Exploit chain validation (safe)

Applicable Scenarios

  • Database unauthorized/weak password/incorrect binding to 0.0.0.0
  • Excessive permissions, dangerous features (xp_cmdshell, COPY PROGRAM, UDF)
  • Lateral movement: From application account to DBA
  • NoSQL injection and Redis file writing, etc. (authorized environments)

Workflow

□ Network exposure and TLS
□ Account roles and grantees
□ Sensitive table access control
□ Dangerous configurations: file_priv, xp_cmdshell, load_file
□ Are audit logs enabled?
□ Backup and snapshot permissions

Toolchain

Tool Purpose
Official CLIs Connection and enumeration
sqlmap Injection validation (authorized)
nuclei Known exposure templates
Cloud RDS console audit Configuration

References

  • references/db-misconfig-checklist.md
  • ../pentest-tools/ ../cloud-k8s/

Routing Context

Upstream: MASTER R35
Downstream: Gaining OS command → attack-chain; Cloud managed → cloud-k8s

Task Completion Self-Check

  • Was unauthorized write/delete avoided?
  • Were configuration issues and exploitable chains differentiated?
  • Checklist completed?
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

database-security is a skill published in the GitHub repository xAmirHamza77/ReverseOps-Skill (4 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 402 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
