  Source control and artifact exposure (.git, .svn, .hg, backups, .env). Use when recon finds VCS paths, 403 on hidden dirs, or backup/config leaks during authorized testing.

# SKILL: Insecure Source Code Management

> **AI LOAD INSTRUCTION**: This skill covers detection and recovery of exposed version-control metadata, common backup artifacts, and related misconfigurations. Use only in **authorized** assessments. Treat recovered credentials and URLs as sensitive; do not exfiltrate real data beyond scope. For broad discovery workflow, cross-load [recon-for-sec](../recon-and-methodology/SKILL.md) and [recon-and-methodology](../recon-and-methodology/SKILL.md) when those skills exist in the workspace.

## 0. QUICK START

High-value paths to probe first (GET or HEAD, respect rate limits):

```http
/.git/HEAD
/.git/config
/.svn/entries
/.svn/wc.db
/.hg/requires
/.bzr/README
/.DS_Store
/.env
```

**中文路由提示**：快速扫这些路径；若需完整侦察流程，从 `recon-for-sec`、`recon-and-methodology` 技能载入方法论后再深入。

## 1. GIT EXPOSURE

### Detection

- **`/.git/HEAD`** — valid repo often returns plain text like:

```text
ref: refs/heads/main
```

- **`/.git/config`** — may expose `remote.origin.url`, user identity, or embedded credentials.
- **`/.git/index`**, **`/.git/objects/`** — partial object store access enables reconstruction with the right tools.

### 403 vs 404

- **`404`** — path likely absent or fully blocked at the edge.
- **`403` on `/.git/`** — directory may **exist** but listing is denied; still try direct file URLs:

```http
/.git/HEAD
/.git/config
/.git/logs/HEAD
/.git/refs/heads/main
```

A **403 on the directory** plus **200 on `HEAD`** strongly indicates exposure.

### Recovery tools (open source)

- **`arthaud/git-dumper`** — dumps reachable `.git` tree when individual files are fetchable.
- **`internetwache/GitTools`** — Dumper, Extractor, Finder modules for partial/corrupt dumps.
- **`WangYihang/GitHacker`** — alternative recovery when standard dumpers miss edge cases.

### Key files to prioritize

| Path | Why it matters |
|------|----------------|
| `.git/config` | Remotes, credentials, hooks paths |
| `.git/logs/HEAD` | Commit history, reflog-style leakage |
| `.git/refs/heads/*` | Branch tips, commit SHAs |
| `.git/packed-refs` | Packed branch/tag refs |
| `.git/objects/**` | Object blobs for reconstruction |

---

## 2. SVN EXPOSURE

### Detection

- **SVN before 1.7**: **`/.svn/entries`** — XML or text metadata listing paths and revisions.
- **SVN ≥ 1.7**: **`/.svn/wc.db`** — SQLite working copy database (`PRAGMA table_info` after download).

Example probe:

```http
GET /.svn/entries HTTP/1.1
GET /.svn/wc.db HTTP/1.1
```

### Recovery

- **`anantshri/svn-extractor`** — automated extraction from exposed `.svn`.
- **Manual**: download `wc.db`, query with `sqlite3` for file paths and checksums, then request **`/.svn/pristine/`** blobs if exposed.

---

## 3. MERCURIAL EXPOSURE

### Detection

- **`/.hg/requires`** — small text file listing repository features; confirms Mercurial metadata.

```http
GET /.hg/requires HTTP/1.1
GET /.hg/store/ HTTP/1.1
```

### Recovery

- **`sahildhar/mercurial_source_code_dumper`** — dumps repository when store paths are reachable.

---

## 4. OTHER LEAKS

### Bazaar (Bzr)

- Probe **`/.bzr/README`** and **`/.bzr/branch-format`** for Bazaar metadata.

### macOS `.DS_Store`
